=== Setting the gimbals ===
Unscrew the 4 screws on the back cover of the transmitter, remove the back cover. From here, you can adjust the rotation of the cross controllers up to 8°, or tune the return spring force and lock. After that loosen the screws, adjust the angle and retighten the screws.


==== Changing the mode ====
From the gimbal menu, change the current mode (mode 2 by default) to the desired mode. Turn off the transmitter, remove the battery case cover and disconnect and remove the battery. Unscrew the 4 screws of the transmitter back cover and remove it (pay extra attention to the attached antennas, they can be disconnected for better handling). To change to the desired mode, loosen the screw holding the self-centering arm mechanism, then screw it into the other gimbal.


You can also adjust the strength of the centering springs and ratchet, and possibly rotate the entire gimbal up to 8 degrees. Put on the back cover of the transmitter, screw in the 4 screws on the back of the transmitter, connect and insert the battery (making sure to maintain the correct polarity) and put the battery tray cover back on.


{{Note|type=error|text='''Caution:''' When using the USB charging function, charge the battery using a suitable USB adapter: voltage: 5±0.2 V; current: >2.0 A.}}


=== Charging the battery ===
Included in the package is a 2S (7.4V) LiPo battery with a capacity of 4000 mAh. The transmitter is equipped with a balancer for charging 2S batteries via a USB-C interface. The size of the battery case is 84×41.5×20mm (L×W×H).


==== LED ====
'''ON''': charging in progress | '''OFF''': charging complete | '''FLASHING''': charging error


=== Navigation controllers ===
The left navigation buttons represent the MODEL/SYSTEM/DISPLAY/BACK functions. The right navigation knob is used to control the display and performs the same functions as the touch control.


=== Software ETHOS Suite ===
The ETHOS Suite can be used to update the transmitter‘s bootloader, firmware, SD card, flash, and also convert image and audio format. Find the latest information and download the ETHOS software at [https://ethos.frsky-rc.com/ www.ethos.frsky-rc.com].


{{Note|type=info|text='''Note:''' To use the ETHOS Suite app with the KAVAN transmitter without problems, always keep the transmitter bootloader on the latest version. Also, back up your current version before upgrading.}}

== Operating system ETHOS == 

=== Creating a model === 


# Open the Model Settings, open Model Selection and select the desired model.
# Configure and name the newly created model.


=== Model setting - internal RF module ===
Select the INT module. Switch on the internal module by switching the „Status“ slider to the „ON“ position. Select the internal or external antenna (two internal antennas and external antennas work simultaneously when selecting Antenna: External). Select the RF protocol according to your receiver type.


{{Note|type=info|text='''Note:''' Although the RF module has built-in protection, we advise to make sure that the external antennas are mounted before selecting Antenna: External. Note that the selection of the antenna type is made for each model separately, so each time you change the model selection, ETHOS will switch on the antenna mode set for that model.}}


==== Channel range ====
The built-in RF module supports up to 24 channels. The range is adjustable and must be checked before use. In the Channel Range menu, select the number of channels you will use for the model.

=== Registration and pairing === 


==== Protocols ACCESS and Twin 2.4GHz ====
Before you start using your transmitter, you must first register the desired receiver.


# Begin the registration process by selecting [Register].
# A window will appear with the message "Waiting...." with a repeating voice prompt "Register". Hold down the pairing button on the receiver and turn it on. Wait for the red and green LEDs to light up.
# The RID and UID can be set at this stage:
# Press the [Register] button to complete the setup. The "Registration OK" dialogue box will appear. Press the [OK] button to continue.
# Turn off the receiver. This registers the receiver. However, you still need to pair it with the transmitter to use it.


*'''RID:''' This is the unique identifier of the transmitter. It can be changed to the same/own code to use the Smart share feature for sharing models (if you want to share models and own multiple transmitters, or if you share models with other modellers, you must have the same RID set on those transmitters). The RID is the transmitter data (Owner Registration ID) written into the receiver‘s memory. If two transmitters have the same RID, you can easily share models including receivers between them using the Smart share function.
*'''RX name''': the naming of the receiver is done automatically when the receiver is paired for the first time. This name can be changed at any time. This is useful when using more than one receiver, e.g. to remember the settings of the receivers, e.g. '''RX4R1''' is for CH1–8 or '''RX4R2''' is for CH9–16 or '''RX4R3''' is for CH17–24.
*'''UID''': is used to distinguish multiple receivers used simultaneously in one model. A default value of 0 may be left for a single receiver. If more than one receiver is to be used in one model, the UID must be changed, usually '''0''' for CH1-8, '''1''' for CH9-16 and '''2''' for CH17-24. Note that this UID cannot be read back from the receiver, so it is a good idea to tag the receiver.


{{Note|type=error|text='''Caution:''' Do not pair with an electric motor connected or with a combustion engine running.}}


'''Pairing'''


Pairing a receiver allows the receiver registered in phase 1 to be paired with one of the transmitters. Thereafter, the receiver will only communicate with this transmitter unless you pair it with another transmitter. Before using the transmitter for the first time, you must check the range of the transmitter.


# Turn off the power to the receiver.
# RX 1 [Pairing]: Select [Pairing] to start the pairing process. Every few seconds, a „Pairing“ voice alert will sound to confirm that you are in pairing mode. A pop-up window will display the message "Waiting for receiver...".
# Turn on the receiver without holding the F/S pairing button. A window will appear with the message "Device selection" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A message will appear indicating that the pairing was successful.
# Switch off the transmitter and receiver.
# Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.


* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.
* If redundant connection is required, repeat for receivers 2 and 3.


==== Protocol ACCST D16 ====
The ACCST D16 protocol does not use a registration system, but only a pairing system.


# Turn off power to the receiver.
# Selecting [Pairing], a pop-up window will appear with a selection of channels, once selected, start the pairing process. Every few seconds, a "Pairing" voice alert will sound to confirm that you are in pairing mode. The pop-up window will display the message "Pairing ...".
# Turn on the receiver, while holding the pairing button F/S. A window will appear with the message "Select Device" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A window will appear with a message that the pairing was successful. Switch off the transmitter and receiver. Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.
* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.


=== Fail-safe emergency rates ===
When Fail-safe is enabled, 3 modes are available: No signal, Hold, Custom.


* '''No signal''': when signal is lost, the receiver does not send a control signal to the rates on any channel. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Hold''': the receiver maintains the rates as they were before the signal was lost. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Custom''': the receiver keeps the rate value on all channels as you preselect it. Select the Fail-safe setting menu. Switch from Disconnect/Hold/Not Set to „Custom“. Select the channel for which you want to set fail-safe rates and confirm the selection. Then set the rates on each desired channel and confirm the selection. Wait 9 seconds for the Fail-safe setting change to take effect.


{{Note|type=info|text='''Note:''' If the fail-safe rates are disabled on the transmitter, the fail-safe rates set on the receiver will automatically be used. The S.BUS connector does not support „Disconnect“ mode, and will always use „Hold“ or „Custom“ mode.}}


=== Range check ===
A pre-flight range check should be performed before each flight. Select the "RF System" section, select either the internal or external module, select "Action", then "Range Check" and confirm the selection. In range check mode, the effective range of the transmitter is reduced to 1/30. Press "Range Check" again to return to normal mode.


A "Range Check" voice alert will sound every few seconds to confirm that you are in range check mode. A pop-up window on the display will show the receiver UID and the VFR % and RSSI values to evaluate the reception quality. Under ideal conditions, when the transmitter and receiver are both 1 m above the ground, the Alarm should appear at a distance of approximately 30 m from each other.

== Conclusion == 


=== Principles of safe operation ===
Operating the models can be dangerous if you do not follow the appropriate safety guidelines. Here are some of the most important recommendations to help ensure safe operation.
* Before taking off, make sure the model responds properly to the gimbal movements on the transmitter. Also make sure all switches and other controls are functioning properly. If you find any problems, do not fly the model until all functions are working properly.
* Never fly in rain, strong winds or at night. Water can cause failure or improper operation and impair the control of the model, with the risk of a crash.


* Never turn off the power switch in flight when the model‘s engine is running or the battery is connected. In this case, control of the model will be impossible, and the model will crash. Even if you turn the switch back on, normal operation will not resume until the internal transmitter and receiver initialization processes are completed.
* Do not start the internal combustion engine or electric motor while wearing the neck strap. The strap can be caught by a spinning propeller, rotor, etc. and cause serious injury.
* Never fly in range check mode In this mode, the transmitter operates at reduced power and a crash could occur.
* Do not fly if you are physically or mentally indisposed, as this can be dangerous to yourself and others. Also, never fly under the influence of alcohol, narcotics or drugs affecting your senses.
* Do not fly near airports, near or over people, near residential buildings, schools, hospitals, or other places where people congregate, near high voltage power lines, tall buildings and structures, or communication facilities.
* If you place the transmitter on the ground in preparation for flight, do not place it in an upright position. The transmitter may tip over, the controls may become misaligned, and the propeller or rotor may spin unexpectedly and cause injury.
* Do not touch internal combustion engines, electric motors or controllers during or immediately after operation. These devices can become very hot during operation.
* For safety reasons, always fly with the model in line of sight at all times. Getting behind buildings or other large objects will not only cause you to lose sight of the model, but the obstruction will prevent the RF signal from the transmitter from propagating and cause you to lose control of the model.
* Always set fail-safe emergency rates for safety. Take special care to set the throttle to neutral in case of an emergency.
* Always check the charge level of the transmitter and receiver batteries before each takeoff. Low voltage will cause loss of control of the model and a crash.
* At the beginning of each flight day, check the operation of all control surfaces and perform a range check. If using the Trainer function, check that the model responds properly to both teacher and student transmitter controls. Even an incorrect setting of a single transmitter or model function can cause a crash.
* Before turning on the transmitter: 1. Always pull the throttle control all the way down (to neutral). 2. Turn the transmitter on first, then the receiver.
* Before turning off the transmitter after the internal combustion engine or electric motor has stopped (is in a condition where it cannot start again): 1. Turn off the receiver power switch. 2. Then turn off the transmitter power switch. If you turn the power on/off in reverse order, the propeller or rotor may spin unexpectedly and cause injury. Also, follow the above order when setting fail-safe emergency rates.
* When setting the transmitter, turn the engine off/shut down unless its operation is necessary for the setting. In the case of an electric motor, disconnect its cables. Use extra caution when setting the transmitter while the motor is running. Ensure that the model is properly secured and cannot come into contact with anyone or anything. An unexpected increase in RPM can cause serious injury.

{{Note|type=info|text='''Note:''' Although the RF module has built-in protection, we advise to make sure that the external antennas are mounted before selecting Antenna: External. Note that the selection of the antenna type is made for each model separately, so each time you change the model selection, ETHOS will switch on the antenna mode set for that model.}}


==== Channel range ====
The built-in RF module supports up to 24 channels. The range is adjustable and must be checked before use. In the Channel Range menu, select the number of channels you will use for the model.

=== Registration and pairing === 


==== Protocols ACCESS and Twin 2.4GHz ====
Before you start using your transmitter, you must first register the desired receiver.


# Begin the registration process by selecting [Register].
# A window will appear with the message "Waiting...." with a repeating voice prompt "Register". Hold down the pairing button on the receiver and turn it on. Wait for the red and green LEDs to light up.
# The RID and UID can be set at this stage:
# Press the [Register] button to complete the setup. The "Registration OK" dialogue box will appear. Press the [OK] button to continue.
# Turn off the receiver. This registers the receiver. However, you still need to pair it with the transmitter to use it.


*'''RID:''' This is the unique identifier of the transmitter. It can be changed to the same/own code to use the Smart share feature for sharing models (if you want to share models and own multiple transmitters, or if you share models with other modellers, you must have the same RID set on those transmitters). The RID is the transmitter data (Owner Registration ID) written into the receiver‘s memory. If two transmitters have the same RID, you can easily share models including receivers between them using the Smart share function.
*'''RX name''': the naming of the receiver is done automatically when the receiver is paired for the first time. This name can be changed at any time. This is useful when using more than one receiver, e.g. to remember the settings of the receivers, e.g. '''RX4R1''' is for CH1–8 or '''RX4R2''' is for CH9–16 or '''RX4R3''' is for CH17–24.
*'''UID''': is used to distinguish multiple receivers used simultaneously in one model. A default value of 0 may be left for a single receiver. If more than one receiver is to be used in one model, the UID must be changed, usually '''0''' for CH1-8, '''1''' for CH9-16 and '''2''' for CH17-24. Note that this UID cannot be read back from the receiver, so it is a good idea to tag the receiver.


{{Note|type=error|text='''Caution:''' Do not pair with an electric motor connected or with a combustion engine running.}}


'''Pairing'''


Pairing a receiver allows the receiver registered in phase 1 to be paired with one of the transmitters. Thereafter, the receiver will only communicate with this transmitter unless you pair it with another transmitter. Before using the transmitter for the first time, you must check the range of the transmitter.


# Turn off the power to the receiver.
# RX 1 [Pairing]: Select [Pairing] to start the pairing process. Every few seconds, a „Pairing“ voice alert will sound to confirm that you are in pairing mode. A pop-up window will display the message "Waiting for receiver...".
# Turn on the receiver without holding the F/S pairing button. A window will appear with the message "Device selection" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A message will appear indicating that the pairing was successful.
# Switch off the transmitter and receiver.
# Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.


* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.
* If redundant connection is required, repeat for receivers 2 and 3.


==== Protocol ACCST D16 ====
The ACCST D16 protocol does not use a registration system, but only a pairing system.


# Turn off power to the receiver.
# Selecting [Pairing], a pop-up window will appear with a selection of channels, once selected, start the pairing process. Every few seconds, a "Pairing" voice alert will sound to confirm that you are in pairing mode. The pop-up window will display the message "Pairing ...".
# Turn on the receiver, while holding the pairing button F/S. A window will appear with the message "Select Device" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A window will appear with a message that the pairing was successful. Switch off the transmitter and receiver. Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.
* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.


=== Fail-safe emergency rates ===
When Fail-safe is enabled, 3 modes are available: No signal, Hold, Custom.


* '''No signal''': when signal is lost, the receiver does not send a control signal to the rates on any channel. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Hold''': the receiver maintains the rates as they were before the signal was lost. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Custom''': the receiver keeps the rate value on all channels as you preselect it. Select the Fail-safe setting menu. Switch from Disconnect/Hold/Not Set to „Custom“. Select the channel for which you want to set fail-safe rates and confirm the selection. Then set the rates on each desired channel and confirm the selection. Wait 9 seconds for the Fail-safe setting change to take effect.


{{Note|type=info|text='''Note:''' If the fail-safe rates are disabled on the transmitter, the fail-safe rates set on the receiver will automatically be used. The S.BUS connector does not support „Disconnect“ mode, and will always use „Hold“ or „Custom“ mode.}}


=== Range check ===
A pre-flight range check should be performed before each flight. Select the "RF System" section, select either the internal or external module, select "Action", then "Range Check" and confirm the selection. In range check mode, the effective range of the transmitter is reduced to 1/30. Press "Range Check" again to return to normal mode.


A "Range Check" voice alert will sound every few seconds to confirm that you are in range check mode. A pop-up window on the display will show the receiver UID and the VFR % and RSSI values to evaluate the reception quality. Under ideal conditions, when the transmitter and receiver are both 1 m above the ground, the Alarm should appear at a distance of approximately 30 m from each other.

== Conclusion == 


=== Principles of safe operation ===
Operating the models can be dangerous if you do not follow the appropriate safety guidelines. Here are some of the most important recommendations to help ensure safe operation.
* Before taking off, make sure the model responds properly to the gimbal movements on the transmitter. Also make sure all switches and other controls are functioning properly. If you find any problems, do not fly the model until all functions are working properly.
* Never fly in rain, strong winds or at night. Water can cause failure or improper operation and impair the control of the model, with the risk of a crash.


* Never turn off the power switch in flight when the model‘s engine is running or the battery is connected. In this case, control of the model will be impossible, and the model will crash. Even if you turn the switch back on, normal operation will not resume until the internal transmitter and receiver initialization processes are completed.
* Do not start the internal combustion engine or electric motor while wearing the neck strap. The strap can be caught by a spinning propeller, rotor, etc. and cause serious injury.
* Never fly in range check mode In this mode, the transmitter operates at reduced power and a crash could occur.
* Do not fly if you are physically or mentally indisposed, as this can be dangerous to yourself and others. Also, never fly under the influence of alcohol, narcotics or drugs affecting your senses.
* Do not fly near airports, near or over people, near residential buildings, schools, hospitals, or other places where people congregate, near high voltage power lines, tall buildings and structures, or communication facilities.
* If you place the transmitter on the ground in preparation for flight, do not place it in an upright position. The transmitter may tip over, the controls may become misaligned, and the propeller or rotor may spin unexpectedly and cause injury.
* Do not touch internal combustion engines, electric motors or controllers during or immediately after operation. These devices can become very hot during operation.
* For safety reasons, always fly with the model in line of sight at all times. Getting behind buildings or other large objects will not only cause you to lose sight of the model, but the obstruction will prevent the RF signal from the transmitter from propagating and cause you to lose control of the model.
* Always set fail-safe emergency rates for safety. Take special care to set the throttle to neutral in case of an emergency.
* Always check the charge level of the transmitter and receiver batteries before each takeoff. Low voltage will cause loss of control of the model and a crash.
* At the beginning of each flight day, check the operation of all control surfaces and perform a range check. If using the Trainer function, check that the model responds properly to both teacher and student transmitter controls. Even an incorrect setting of a single transmitter or model function can cause a crash.
* Before turning on the transmitter: 1. Always pull the throttle control all the way down (to neutral). 2. Turn the transmitter on first, then the receiver.
* Before turning off the transmitter after the internal combustion engine or electric motor has stopped (is in a condition where it cannot start again): 1. Turn off the receiver power switch. 2. Then turn off the transmitter power switch. If you turn the power on/off in reverse order, the propeller or rotor may spin unexpectedly and cause injury. Also, follow the above order when setting fail-safe emergency rates.
* When setting the transmitter, turn the engine off/shut down unless its operation is necessary for the setting. In the case of an electric motor, disconnect its cables. Use extra caution when setting the transmitter while the motor is running. Ensure that the model is properly secured and cannot come into contact with anyone or anything. An unexpected increase in RPM can cause serious injury.

* Do not touch internal combustion engines, electric motors or controllers during or immediately after operation. These devices can become very hot during operation.
* For safety reasons, always fly with the model in line of sight at all times. Getting behind buildings or other large objects will not only cause you to lose sight of the model, but the obstruction will prevent the RF signal from the transmitter from propagating and cause you to lose control of the model.
* Always set fail-safe emergency rates for safety. Take special care to set the throttle to neutral in case of an emergency.
* Always check the charge level of the transmitter and receiver batteries before each takeoff. Low voltage will cause loss of control of the model and a crash.
* At the beginning of each flight day, check the operation of all control surfaces and perform a range check. If using the Trainer function, check that the model responds properly to both teacher and student transmitter controls. Even an incorrect setting of a single transmitter or model function can cause a crash.
* Before turning on the transmitter: 1. Always pull the throttle control all the way down (to neutral). 2. Turn the transmitter on first, then the receiver.
* Before turning off the transmitter after the internal combustion engine or electric motor has stopped (is in a condition where it cannot start again): 1. Turn off the receiver power switch. 2. Then turn off the transmitter power switch. If you turn the power on/off in reverse order, the propeller or rotor may spin unexpectedly and cause injury. Also, follow the above order when setting fail-safe emergency rates.
* When setting the transmitter, turn the engine off/shut down unless its operation is necessary for the setting. In the case of an electric motor, disconnect its cables. Use extra caution when setting the transmitter while the motor is running. Ensure that the model is properly secured and cannot come into contact with anyone or anything. An unexpected increase in RPM can cause serious injury.

***'''Voltage level''' – Uses a logical voltage level on the Rx signal input (2.0V – 5.0V = ON, 0.0 - 0.7V = OFF). Always supply the voltage through the “Rx” cable. A pulldown resistor is automatically enabled on the input.
***'''Serial bus channel''' – Uses a specific channel from the serial bus (S.Bus, EX Bus, P2Bus, F.Port, F.Bus) to control the switch. The Rx cable must be connected to the receiver bus output.
**'''Servo threshold''' – Sets the servo signal threshold for switching. Values above the threshold (default: 1.5 ms) activate the output; lower values deactivate it.
**'''Serial bus channel''' – Allows selection of a specific channel when the Input Type is set to Serial Bus Channel.
**'''Secondary input''' (None/Mechanical/Hall/Button/Touch). Optional secondary control input type. The secondary input can include an indicator LED.
**'''Touch sensitivity''' – Adjusts the sensitivity of the touch sensor. Higher values allow installation behind thicker non-conductive surfaces but may increase the risk of false activation.
**'''Switch behavior''' – Determines how the primary and secondary inputs interact:
***Only primary input (default) – The switch is controlled exclusively by the primary input.
***Both primary and secondary – Both inputs must be active to enable the output. If either input is inactive, the switch turns off and the.
***Only secondary input – The switch is controlled solely by the secondary input.
**'''Invert output''' – Inverts the logical output state of the switch in response to the control signal.
**'''Required startup position''' – Defines the switch’s behavior at power-up:
***Any position (default) – The switch reacts immediately to the control signal.
***Off position - The output remains off at startup and becomes responsive only after the input signal goes off.
***On position - The output is active at startup and becomes responsive after the input signal goes on.
**'''FailSafe Behavior''' – Configures the switch’s response to a lost control signal:.
***Repeat – Maintains the last known state.
***Turn off – Sets the output to OFF.
***Turn on – Sets the output to ON.
**'''FailSafe Delay''' – Specifies the delay time between signal loss and fail-safe activation.
*'''Service''' – Displays device firmware version and allows resetting to factory default settings.

====== JETIBOX menu structure ======
obrazek tu

====== FrSky/Kavan integration ======
The KSW18 is compatible with FPort and FBus capable receivers, allowing both control, telemetry and configuration capabilities. The switch receives channel information and sends back telemetry data. It can decode all channel data from FBus 8 up to FBus 24, but only the first 16 channels can be used for internal functions, such as switch control.

To configure the KSW18, the Ethos system (minimum version 1.6) is required. You need to download the corresponding Lua application to your transmitter and place it in the "scripts" folder. Launch the application from the second page of the Configuration menu. Note that only one KSW18 should be connected to the telemetry bus at a time to avoid address conflicts.

**'''Input type''' – defines the primary input control for the switch:
***'''Servo signal''' (default) – Uses a PWM signal from the receiver to control the switch state.
***'''Voltage level''' – Uses a logical voltage level on the Rx signal input (2.0V – 5.0V = ON, 0.0 - 0.7V = OFF). Always supply the voltage through the “Rx” cable. A pulldown resistor is automatically enabled on the input.
***'''Serial bus channel''' – Uses a specific channel from the serial bus (S.Bus, EX Bus, P2Bus, F.Port, F.Bus) to control the switch. The Rx cable must be connected to the receiver bus output.
**'''Servo threshold''' – Sets the servo signal threshold for switching. Values above the threshold (default: 1.5 ms) activate the output; lower values deactivate it.
**'''Serial bus channel''' – Allows selection of a specific channel when the Input Type is set to Serial Bus Channel.
**'''Secondary input''' (None/Mechanical/Hall/Button/Touch). Optional secondary control input
type. The secondary input can include an indicator LED.
**'''Touch sensitivity''' – Adjusts the sensitivity of the touch sensor. Higher values allow installation behind thicker non-conductive surfaces but may increase the risk of false activation.
**'''Switch behavior''' – Determines how the primary and secondary inputs interact:
***Only primary input (default) – The switch is controlled exclusively by the primary input.
***Both primary and secondary – Both inputs must be active to enable the output. If either input is inactive, the switch turns off and the.
***Only secondary input – The switch is controlled solely by the secondary input.
**'''Invert output''' – Inverts the logical output state of the switch in response to the control signal.
**'''Required startup position''' – Defines the switch’s behavior at power-up:
***Any position (default) – The switch reacts immediately to the control signal.
***Off position - The output remains off at startup and becomes responsive only after the input signal goes off.
***On position - The output is active at startup and becomes responsive after the input signal goes on.
**'''FailSafe Behavior''' – Configures the switch’s response to a lost control signal:.
***Repeat – Maintains the last known state.
***Turn off – Sets the output to OFF.
***Turn on – Sets the output to ON.
**'''FailSafe Delay''' – Specifies the delay time between signal loss and fail-safe activation.
*'''Service''' – Displays device firmware version and allows resetting to factory default settings.

====== FrSky/Kavan integration ======
The KSW18 is compatible with FPort and FBus capable receivers, allowing both control, telemetry and configuration capabilities. The switch receives channel information and sends back telemetry data. It can decode all channel data from FBus 8 up to FBus 24, but only the first 16 channels can be used for internal functions, such as switch control.

To configure the KSW18, the Ethos system (minimum version 1.6) is required. You need to download the corresponding Lua application to your transmitter and place it in the "scripts" folder. Launch the application from the second page of the Configuration menu. Note that only one KSW18 should be connected to the telemetry bus at a time to avoid address conflicts.

==== LED ====
'''ON''': charging in progress | '''OFF''': charging complete | '''FLASHING''': charging error

=== Navigation controllers ===
The left navigation buttons represent the MODEL/SYSTEM/DISPLAY/BACK functions. The right navigation knob is used to control the display and performs the same functions as the touch control.

=== Software ETHOS Suite ===
The ETHOS Suite can be used to update the transmitter‘s bootloader, firmware, SD card, flash, and also convert image and audio format. Find the latest information and download the ETHOS software at [https://ethos.frsky-rc.com/ www.ethos.frsky-rc.com].

{{Note|type=info|text='''Note:''' To use the ETHOS Suite app with the KAVAN transmitter without problems, always keep the transmitter bootloader on the latest version. Also, back up your current version before upgrading.}}

== Operating system ETHOS ==

=== Creating a model ===

# Open the Model Settings, open Model Selection and select the desired model.
# Configure and name the newly created model.

=== Model setting - internal RF module ===
Select the INT module. Switch on the internal module by switching the „Status“ slider to the „ON“ position. Select the internal or external antenna (two internal antennas and external antennas work simultaneously when selecting Antenna: External). Select the RF protocol according to your receiver type.

{{Note|type=info|text='''Note:''' Although the RF module has built-in protection, we advise to make sure that the external antennas are mounted before selecting Antenna: External. Note that the selection of the antenna type is made for each model separately, so each time you change the model selection, ETHOS will switch on the antenna mode set for that model.}}

==== Channel range ====
The built-in RF module supports up to 24 channels. The range is adjustable and must be checked before use. In the Channel Range menu, select the number of channels you will use for the model.

=== Registration and pairing ===

==== Protocols ACCESS and Twin 2.4GHz ====
Before you start using your transmitter, you must first register the desired receiver.

# Begin the registration process by selecting [Register].
# A window will appear with the message "Waiting...." with a repeating voice prompt "Register". Hold down the pairing button on the receiver and turn it on. Wait for the red and green LEDs to light up.
# The RID and UID can be set at this stage:
# Press the [Register] button to complete the setup. The "Registration OK" dialogue box will appear. Press the [OK] button to continue.
# Turn off the receiver. This registers the receiver. However, you still need to pair it with the transmitter to use it.

*'''RID:''' This is the unique identifier of the transmitter. It can be changed to the same/own code to use the Smart share feature for sharing models (if you want to share models and own multiple transmitters, or if you share models with other modellers, you must have the same RID set on those transmitters). The RID is the transmitter data (Owner Registration ID) written into the receiver‘s memory. If two transmitters have the same RID, you can easily share models including receivers between them using the Smart share function.
*'''RX name''': the naming of the receiver is done automatically when the receiver is paired for the first time. This name can be changed at any time. This is useful when using more than one receiver, e.g. to remember the settings of the receivers, e.g. '''RX4R1''' is for CH1–8 or '''RX4R2''' is for CH9–16 or '''RX4R3''' is for CH17–24.
*'''UID''': is used to distinguish multiple receivers used simultaneously in one model. A default value of 0 may be left for a single receiver. If more than one receiver is to be used in one model, the UID must be changed, usually '''0''' for CH1-8, '''1''' for CH9-16 and '''2''' for CH17-24. Note that this UID cannot be read back from the receiver, so it is a good idea to tag the receiver.

{{Note|type=error|text='''Caution:''' Do not pair with an electric motor connected or with a combustion engine running.}}

'''Pairing'''

Pairing a receiver allows the receiver registered in phase 1 to be paired with one of the transmitters. Thereafter, the receiver will only communicate with this transmitter unless you pair it with another transmitter. Before using the transmitter for the first time, you must check the range of the transmitter.

# Turn off the power to the receiver.
# RX 1 [Pairing]: Select [Pairing] to start the pairing process. Every few seconds, a „Pairing“ voice alert will sound to confirm that you are in pairing mode. A pop-up window will display the message "Waiting for receiver...".
# Turn on the receiver without holding the F/S pairing button. A window will appear with the message "Device selection" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A message will appear indicating that the pairing was successful.
# Switch off the transmitter and receiver.
# Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.

* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.
* If redundant connection is required, repeat for receivers 2 and 3.

==== Protocol ACCST D16 ====
The ACCST D16 protocol does not use a registration system, but only a pairing system.

# Turn off power to the receiver.
# Selecting [Pairing], a pop-up window will appear with a selection of channels, once selected, start the pairing process. Every few seconds, a "Pairing" voice alert will sound to confirm that you are in pairing mode. The pop-up window will display the message "Pairing ...".
# Turn on the receiver, while holding the pairing button F/S. A window will appear with the message "Select Device" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A window will appear with a message that the pairing was successful. Switch off the transmitter and receiver. Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.
* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.

=== Fail-safe emergency rates ===
When Fail-safe is enabled, 3 modes are available: No signal, Hold, Custom.

* '''No signal''': when signal is lost, the receiver does not send a control signal to the rates on any channel. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Hold''': the receiver maintains the rates as they were before the signal was lost. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Custom''': the receiver keeps the rate value on all channels as you preselect it. Select the Fail-safe setting menu. Switch from Disconnect/Hold/Not Set to „Custom“. Select the channel for which you want to set fail-safe rates and confirm the selection. Then set the rates on each desired channel and confirm the selection. Wait 9 seconds for the Fail-safe setting change to take effect.

{{Note|type=info|text='''Note:''' If the fail-safe rates are disabled on the transmitter, the fail-safe rates set on the receiver will automatically be used. The S.BUS connector does not support „Disconnect“ mode, and will always use „Hold“ or „Custom“ mode.}}

=== Range check ===
A pre-flight range check should be performed before each flight. Select the "RF System" section, select either the internal or external module, select "Action", then "Range Check" and confirm the selection. In range check mode, the effective range of the transmitter is reduced to 1/30. Press "Range Check" again to return to normal mode.

A "Range Check" voice alert will sound every few seconds to confirm that you are in range check mode. A pop-up window on the display will show the receiver UID and the VFR % and RSSI values to evaluate the reception quality. Under ideal conditions, when the transmitter and receiver are both 1 m above the ground, the Alarm should appear at a distance of approximately 30 m from each other.

== Conclusion ==

=== Principles of safe operation ===
Operating the models can be dangerous if you do not follow the appropriate safety guidelines. Here are some of the most important recommendations to help ensure safe operation.
* Before taking off, make sure the model responds properly to the gimbal movements on the transmitter. Also make sure all switches and other controls are functioning properly. If you find any problems, do not fly the model until all functions are working properly.
* Never fly in rain, strong winds or at night. Water can cause failure or improper operation and impair the control of the model, with the risk of a crash.

* Never turn off the power switch in flight when the model‘s engine is running or the battery is connected. In this case, control of the model will be impossible, and the model will crash. Even if you turn the switch back on, normal operation will not resume until the internal transmitter and receiver initialization processes are completed.
* Do not start the internal combustion engine or electric motor while wearing the neck strap. The strap can be caught by a spinning propeller, rotor, etc. and cause serious injury.
* Never fly in range check mode In this mode, the transmitter operates at reduced power and a crash could occur.
* Do not fly if you are physically or mentally indisposed, as this can be dangerous to yourself and others. Also, never fly under the influence of alcohol, narcotics or drugs affecting your senses.
* Do not fly near airports, near or over people, near residential buildings, schools, hospitals, or other places where people congregate, near high voltage power lines, tall buildings and structures, or communication facilities.
* If you place the transmitter on the ground in preparation for flight, do not place it in an upright position. The transmitter may tip over, the controls may become misaligned, and the propeller or rotor may spin unexpectedly and cause injury.
* Do not touch internal combustion engines, electric motors or controllers during or immediately after operation. These devices can become very hot during operation.
* For safety reasons, always fly with the model in line of sight at all times. Getting behind buildings or other large objects will not only cause you to lose sight of the model, but the obstruction will prevent the RF signal from the transmitter from propagating and cause you to lose control of the model.
* Always set fail-safe emergency rates for safety. Take special care to set the throttle to neutral in case of an emergency.
* Always check the charge level of the transmitter and receiver batteries before each takeoff. Low voltage will cause loss of control of the model and a crash.
* At the beginning of each flight day, check the operation of all control surfaces and perform a range check. If using the Trainer function, check that the model responds properly to both teacher and student transmitter controls. Even an incorrect setting of a single transmitter or model function can cause a crash.
* Before turning on the transmitter: 1. Always pull the throttle control all the way down (to neutral). 2. Turn the transmitter on first, then the receiver.
* Before turning off the transmitter after the internal combustion engine or electric motor has stopped (is in a condition where it cannot start again): 1. Turn off the receiver power switch. 2. Then turn off the transmitter power switch. If you turn the power on/off in reverse order, the propeller or rotor may spin unexpectedly and cause injury. Also, follow the above order when setting fail-safe emergency rates.
* When setting the transmitter, turn the engine off/shut down unless its operation is necessary for the setting. In the case of an electric motor, disconnect its cables. Use extra caution when setting the transmitter while the motor is running. Ensure that the model is properly secured and cannot come into contact with anyone or anything. An unexpected increase in RPM can cause serious injury.

=== Setting the gimbals ===
Unscrew the 4 screws on the back cover of the transmitter, remove the back cover. From here, you can adjust the rotation of the cross controllers up to 8°, or tune the return spring force and lock. After that loosen the screws, adjust the angle and retighten the screws.

==== Changing the mode ====
From the gimbal menu, change the current mode (mode 2 by default) to the desired mode. Turn off the transmitter, remove the battery case cover and disconnect and remove the battery. Unscrew the 4 screws of the transmitter back cover and remove it (pay extra attention to the attached antennas, they can be disconnected for better handling). To change to the desired mode, loosen the screw holding the self-centering arm mechanism, then screw it into the other gimbal.

You can also adjust the strength of the centring springs and ratchet, and possibly rotate the entire gimbal up to 8 degrees. Put on the back cover of the transmitter, screw in the 4 screws on the back of the transmitter, connect and insert the battery (making sure to maintain the correct polarity) and put the battery tray cover back on.

{{Note|type=error|text='''Caution:''' When using the USB charging function, charge the battery using a suitable USB adapter: voltage: 5±0.2 V; current: >2.0 A.}}

==== LED ====
'''ON''': charging in progress | '''OFF''': charging complete | '''FLASHING''': charging error

=== Navigation controllers ===
The left navigation buttons represent the MODEL/SYSTEM/DISPLAY/BACK functions. The right navigation knob is used to control the display and performs the same functions as the touch control.

=== Software ETHOS Suite ===
The ETHOS Suite can be used to update the transmitter‘s bootloader, firmware, SD card, flash, and also convert image and audio format. Find the latest information and download the ETHOS software at [https://ethos.frsky-rc.com/ www.ethos.frsky-rc.com].

{{Note|type=info|text='''Note:''' To use the ETHOS Suite app with the KAVAN transmitter without problems, always keep the transmitter bootloader on the latest version. Also, back up your current version before upgrading.}}

== Operating system ETHOS ==

=== Creating a model ===

# Open the Model Settings, open Model Selection and select the desired model.
# Configure and name the newly created model.

=== Model setting - internal RF module ===
Select the INT module. Switch on the internal module by switching the „Status“ slider to the „ON“ position. Select the internal or external antenna (two internal antennas and external antennas work simultaneously when selecting Antenna: External). Select the RF protocol according to your receiver type.

{{Note|type=info|text='''Note:''' Although the RF module has built-in protection, we advise to make sure that the external antennas are mounted before selecting Antenna: External. Note that the selection of the antenna type is made for each model separately, so each time you change the model selection, ETHOS will switch on the antenna mode set for that model.}}

==== Channel range ====
The built-in RF module supports up to 24 channels. The range is adjustable and must be checked before use. In the Channel Range menu, select the number of channels you will use for the model.

=== Registration and pairing ===

==== Protocols ACCESS and Twin 2.4GHz ====
Before you start using your transmitter, you must first register the desired receiver.

# Begin the registration process by selecting [Register].
# A window will appear with the message "Waiting...." with a repeating voice prompt "Register". Hold down the pairing button on the receiver and turn it on. Wait for the red and green LEDs to light up.
# The RID and UID can be set at this stage:
# Press the [Register] button to complete the setup. The "Registration OK" dialogue box will appear. Press the [OK] button to continue.
# Turn off the receiver. This registers the receiver. However, you still need to pair it with the transmitter to use it.

*'''RID:''' This is the unique identifier of the transmitter. It can be changed to the same/own code to use the Smart share feature for sharing models (if you want to share models and own multiple transmitters, or if you share models with other modellers, you must have the same RID set on those transmitters). The RID is the transmitter data (Owner Registration ID) written into the receiver‘s memory. If two transmitters have the same RID, you can easily share models including receivers between them using the Smart share function.
*'''RX name''': the naming of the receiver is done automatically when the receiver is paired for the first time. This name can be changed at any time. This is useful when using more than one receiver, e.g. to remember the settings of the receivers, e.g. '''RX4R1''' is for CH1–8 or '''RX4R2''' is for CH9–16 or '''RX4R3''' is for CH17–24.
*'''UID''': is used to distinguish multiple receivers used simultaneously in one model. A default value of 0 may be left for a single receiver. If more than one receiver is to be used in one model, the UID must be changed, usually '''0''' for CH1-8, '''1''' for CH9-16 and '''2''' for CH17-24. Note that this UID cannot be read back from the receiver, so it is a good idea to tag the receiver.

{{Note|type=error|text='''Caution:''' Do not pair with an electric motor connected or with a combustion engine running.}}

'''Pairing'''

Pairing a receiver allows the receiver registered in phase 1 to be paired with one of the transmitters. Thereafter, the receiver will only communicate with this transmitter unless you pair it with another transmitter. Before using the transmitter for the first time, you must check the range of the transmitter.

# Turn off the power to the receiver.
# RX 1 [Pairing]: Select [Pairing] to start the pairing process. Every few seconds, a „Pairing“ voice alert will sound to confirm that you are in pairing mode. A pop-up window will display the message "Waiting for receiver...".
# Turn on the receiver without holding the F/S pairing button. A window will appear with the message "Device selection" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A message will appear indicating that the pairing was successful.
# Switch off the transmitter and receiver.
# Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.

* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.
* If redundant connection is required, repeat for receivers 2 and 3.

==== Protocol ACCST D16 ====
The ACCST D16 protocol does not use a registration system, but only a pairing system.

# Turn off power to the receiver.
# Selecting [Pairing], a pop-up window will appear with a selection of channels, once selected, start the pairing process. Every few seconds, a "Pairing" voice alert will sound to confirm that you are in pairing mode. The pop-up window will display the message "Pairing ...".
# Turn on the receiver, while holding the pairing button F/S. A window will appear with the message "Select Device" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A window will appear with a message that the pairing was successful. Switch off the transmitter and receiver. Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.
* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.

=== Fail-safe emergency rates ===
When Fail-safe is enabled, 3 modes are available: No signal, Hold, Custom.

* '''No signal''': when signal is lost, the receiver does not send a control signal to the rates on any channel. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Hold''': the receiver maintains the rates as they were before the signal was lost. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Custom''': the receiver keeps the rate value on all channels as you preselect it. Select the Fail-safe setting menu. Switch from Disconnect/Hold/Not Set to „Custom“. Select the channel for which you want to set fail-safe rates and confirm the selection. Then set the rates on each desired channel and confirm the selection. Wait 9 seconds for the Fail-safe setting change to take effect.

{{Note|type=info|text='''Note:''' If the fail-safe rates are disabled on the transmitter, the fail-safe rates set on the receiver will automatically be used. The S.BUS connector does not support „Disconnect“ mode, and will always use „Hold“ or „Custom“ mode.}}

=== Range check ===
A pre-flight range check should be performed before each flight. Select the "RF System" section, select either the internal or external module, select "Action", then "Range Check" and confirm the selection. In range check mode, the effective range of the transmitter is reduced to 1/30. Press "Range Check" again to return to normal mode.

A "Range Check" voice alert will sound every few seconds to confirm that you are in range check mode. A pop-up window on the display will show the receiver UID and the VFR % and RSSI values to evaluate the reception quality. Under ideal conditions, when the transmitter and receiver are both 1 m above the ground, the Alarm should appear at a distance of approximately 30 m from each other.

== Conclusion ==

=== Principles of safe operation ===
Operating the models can be dangerous if you do not follow the appropriate safety guidelines. Here are some of the most important recommendations to help ensure safe operation.
* Before taking off, make sure the model responds properly to the gimbal movements on the transmitter. Also make sure all switches and other controls are functioning properly. If you find any problems, do not fly the model until all functions are working properly.
* Never fly in rain, strong winds or at night. Water can cause failure or improper operation and impair the control of the model, with the risk of a crash.

* Never turn off the power switch in flight when the model‘s engine is running or the battery is connected. In this case, control of the model will be impossible, and the model will crash. Even if you turn the switch back on, normal operation will not resume until the internal transmitter and receiver initialization processes are completed.
* Do not start the internal combustion engine or electric motor while wearing the neck strap. The strap can be caught by a spinning propeller, rotor, etc. and cause serious injury.
* Never fly in range check mode In this mode, the transmitter operates at reduced power and a crash could occur.
* Do not fly if you are physically or mentally indisposed, as this can be dangerous to yourself and others. Also, never fly under the influence of alcohol, narcotics or drugs affecting your senses.
* Do not fly near airports, near or over people, near residential buildings, schools, hospitals, or other places where people congregate, near high voltage power lines, tall buildings and structures, or communication facilities.
* If you place the transmitter on the ground in preparation for flight, do not place it in an upright position. The transmitter may tip over, the controls may become misaligned, and the propeller or rotor may spin unexpectedly and cause injury.
* Do not touch internal combustion engines, electric motors or controllers during or immediately after operation. These devices can become very hot during operation.
* For safety reasons, always fly with the model in line of sight at all times. Getting behind buildings or other large objects will not only cause you to lose sight of the model, but the obstruction will prevent the RF signal from the transmitter from propagating and cause you to lose control of the model.
* Always set fail-safe emergency rates for safety. Take special care to set the throttle to neutral in case of an emergency.
* Always check the charge level of the transmitter and receiver batteries before each takeoff. Low voltage will cause loss of control of the model and a crash.
* At the beginning of each flight day, check the operation of all control surfaces and perform a range check. If using the Trainer function, check that the model responds properly to both teacher and student transmitter controls. Even an incorrect setting of a single transmitter or model function can cause a crash.
* Before turning on the transmitter: 1. Always pull the throttle control all the way down (to neutral). 2. Turn the transmitter on first, then the receiver.
* Before turning off the transmitter after the internal combustion engine or electric motor has stopped (is in a condition where it cannot start again): 1. Turn off the receiver power switch. 2. Then turn off the transmitter power switch. If you turn the power on/off in reverse order, the propeller or rotor may spin unexpectedly and cause injury. Also, follow the above order when setting fail-safe emergency rates.
* When setting the transmitter, turn the engine off/shut down unless its operation is necessary for the setting. In the case of an electric motor, disconnect its cables. Use extra caution when setting the transmitter while the motor is running. Ensure that the model is properly secured and cannot come into contact with anyone or anything. An unexpected increase in RPM can cause serious injury.

Note that the selection of the antenna type is made for each model separately, so each time you change the model selection, ETHOS will switch on the antenna mode set for that model.}}

==== Channel range ====
The built-in RF module supports up to 24 channels. The range is adjustable and must be checked before use. In the Channel Range menu, select the number of channels you will use for the model.

=== Registration and pairing ===

==== Protocols ACCESS and Twin 2.4GHz ====
Before you start using your transmitter, you must first register the desired receiver.

# Begin the registration process by selecting [Register].
# A window will appear with the message "Waiting...." with a repeating voice prompt "Register". Hold down the pairing button on the receiver and turn it on. Wait for the red and green LEDs to light up.
# The RID and UID can be set at this stage:
# Press the [Register] button to complete the setup. The "Registration OK" dialogue box will appear. Press the [OK] button to continue.
# Turn off the receiver. This registers the receiver. However, you still need to pair it with the transmitter to use it.

*'''RID:''' This is the unique identifier of the transmitter. It can be changed to the same/own code to use the Smart share feature for sharing models (if you want to share models and own multiple transmitters, or if you share models with other modellers, you must have the same RID set on those transmitters). The RID is the transmitter data (Owner Registration ID) written into the receiver‘s memory. If two transmitters have the same RID, you can easily share models including receivers between them using the Smart share function.
*'''RX name''': the naming of the receiver is done automatically when the receiver is paired for the first time. This name can be changed at any time. This is useful when using more than one receiver, e.g. to remember the settings of the receivers, e.g. '''RX4R1''' is for CH1–8 or '''RX4R2''' is for CH9–16 or '''RX4R3''' is for CH17–24.
*'''UID''': is used to distinguish multiple receivers used simultaneously in one model. A default value of 0 may be left for a single receiver. If more than one receiver is to be used in one model, the UID must be changed, usually '''0''' for CH1-8, '''1''' for CH9-16 and '''2''' for CH17-24. Note that this UID cannot be read back from the receiver, so it is a good idea to tag the receiver.

{{Note|type=error|text='''Caution:''' Do not pair with an electric motor connected or with a combustion engine running.}}

'''Pairing'''

Pairing a receiver allows the receiver registered in phase 1 to be paired with one of the transmitters. Thereafter, the receiver will only communicate with this transmitter unless you pair it with another transmitter. Before using the transmitter for the first time, you must check the range of the transmitter.

# Turn off the power to the receiver.
# RX 1 [Pairing]: Select [Pairing] to start the pairing process. Every few seconds, a „Pairing“ voice alert will sound to confirm that you are in pairing mode. A pop-up window will display the message "Waiting for receiver...".
# Turn on the receiver without holding the F/S pairing button. A window will appear with the message "Device selection" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A message will appear indicating that the pairing was successful.
# Switch off the transmitter and receiver.
# Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.

* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.
* If redundant connection is required, repeat for receivers 2 and 3.

==== Protocol ACCST D16 ====
The ACCST D16 protocol does not use a registration system, but only a pairing system.

# Turn off power to the receiver.
# Selecting [Pairing], a pop-up window will appear with a selection of channels, once selected, start the pairing process. Every few seconds, a "Pairing" voice alert will sound to confirm that you are in pairing mode. The pop-up window will display the message "Pairing ...".
# Turn on the receiver, while holding the pairing button F/S. A window will appear with the message "Select Device" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A window will appear with a message that the pairing was successful. Switch off the transmitter and receiver. Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.
* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.

=== Fail-safe emergency rates ===
When Fail-safe is enabled, 3 modes are available: No signal, Hold, Custom.

* '''No signal''': when signal is lost, the receiver does not send a control signal to the rates on any channel. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Hold''': the receiver maintains the rates as they were before the signal was lost. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Custom''': the receiver keeps the rate value on all channels as you preselect it. Select the Fail-safe setting menu. Switch from Disconnect/Hold/Not Set to „Custom“. Select the channel for which you want to set fail-safe rates and confirm the selection. Then set the rates on each desired channel and confirm the selection. Wait 9 seconds for the Fail-safe setting change to take effect.

{{Note|type=info|text='''Note:''' If the fail-safe rates are disabled on the transmitter, the fail-safe rates set on the receiver will automatically be used. The S.BUS connector does not support „Disconnect“ mode, and will always use „Hold“ or „Custom“ mode.}}

=== Range check ===
A pre-flight range check should be performed before each flight. Select the "RF System" section, select either the internal or external module, select "Action", then "Range Check" and confirm the selection. In range check mode, the effective range of the transmitter is reduced to 1/30. Press "Range Check" again to return to normal mode.

A "Range Check" voice alert will sound every few seconds to confirm that you are in range check mode. A pop-up window on the display will show the receiver UID and the VFR % and RSSI values to evaluate the reception quality. Under ideal conditions, when the transmitter and receiver are both 1 m above the ground, the Alarm should appear at a distance of approximately 30 m from each other.

== Conclusion ==

=== Principles of safe operation ===
Operating the models can be dangerous if you do not follow the appropriate safety guidelines. Here are some of the most important recommendations to help ensure safe operation.
* Before taking off, make sure the model responds properly to the gimbal movements on the transmitter. Also make sure all switches and other controls are functioning properly. If you find any problems, do not fly the model until all functions are working properly.
* Never fly in rain, strong winds or at night. Water can cause failure or improper operation and impair the control of the model, with the risk of a crash.

* Never turn off the power switch in flight when the model‘s engine is running or the battery is connected. In this case, control of the model will be impossible, and the model will crash. Even if you turn the switch back on, normal operation will not resume until the internal transmitter and receiver initialization processes are completed.
* Do not start the internal combustion engine or electric motor while wearing the neck strap. The strap can be caught by a spinning propeller, rotor, etc. and cause serious injury.
* Never fly in range check mode In this mode, the transmitter operates at reduced power and a crash could occur.
* Do not fly if you are physically or mentally indisposed, as this can be dangerous to yourself and others. Also, never fly under the influence of alcohol, narcotics or drugs affecting your senses.
* Do not fly near airports, near or over people, near residential buildings, schools, hospitals, or other places where people congregate, near high voltage power lines, tall buildings and structures, or communication facilities.
* If you place the transmitter on the ground in preparation for flight, do not place it in an upright position. The transmitter may tip over, the controls may become misaligned, and the propeller or rotor may spin unexpectedly and cause injury.
* Do not touch internal combustion engines, electric motors or controllers during or immediately after operation. These devices can become very hot during operation.
* For safety reasons, always fly with the model in line of sight at all times. Getting behind buildings or other large objects will not only cause you to lose sight of the model, but the obstruction will prevent the RF signal from the transmitter from propagating and cause you to lose control of the model.
* Always set fail-safe emergency rates for safety. Take special care to set the throttle to neutral in case of an emergency.
* Always check the charge level of the transmitter and receiver batteries before each takeoff. Low voltage will cause loss of control of the model and a crash.
* At the beginning of each flight day, check the operation of all control surfaces and perform a range check. If using the Trainer function, check that the model responds properly to both teacher and student transmitter controls. Even an incorrect setting of a single transmitter or model function can cause a crash.
* Before turning on the transmitter: 1. Always pull the throttle control all the way down (to neutral). 2. Turn the transmitter on first, then the receiver.
* Before turning off the transmitter after the internal combustion engine or electric motor has stopped (is in a condition where it cannot start again): 1. Turn off the receiver power switch. 2. Then turn off the transmitter power switch. If you turn the power on/off in reverse order, the propeller or rotor may spin unexpectedly and cause injury. Also, follow the above order when setting fail-safe emergency rates.
* When setting the transmitter, turn the engine off/shut down unless its operation is necessary for the setting. In the case of an electric motor, disconnect its cables. Use extra caution when setting the transmitter while the motor is running. Ensure that the model is properly secured and cannot come into contact with anyone or anything. An unexpected increase in RPM can cause serious injury.

Mr. KAVAN CS:

=== Introduction ===
Congratulations on purchasing the '''Smart PRO MPSW15 Magnetic switch''', a high-performance digital switch of the "REMOVE BEFORE FLIGHT" type. It operates using magnetic activation – inserting the supplied magnetic activation pin into the opening
disconnects the power (opens the circuit). Removing the pin switches the device on and activates the
connected circuit. The powered-on state is indicated by illuminated LED indicators.
This system offers a safe and reliable solution for switching receivers, ignition systems, and other onboard electronics without the need for mechanical contacts.
The switch provides reliable and secure control via a magnet, supports various types of loads including
inductive, and—being contactless—has no wear due to switching cycles or current flow.

=== Features ===

* LED indication of powered-on state
* Reliable and secure control via a magnet
* Eazy to use

==== Safety information ====
* Operate the AMS always in a dry environment and within the device limits stated in this guide. Never expose the device to excessive heat or cold.
* Never apply mechanical stress or excessive force to the AMS. The sensing element can measure imprecisely or be damaged if a force is applied.
* Do not remove the heat shrink tube from the device and do not try to implement any changes or modifications. It may result in damage to the product and denial of any warranty claims.
* Always check the polarity of the connection. Never inverse the polarity – this could lead to total destruction.

Shielding materials, such as metal, carbon or anything conducting, can reduce the position detection performance. Additionally, make sure that the 2.4GHz antennas are located at least 20 cm or more from the GPS Logger. Try to avoid any mechanical stress on the sensor and avoid any close contact with components producing heat (such as motors or speed controllers). Use a soft double-sided adhesive tape, or Velcro as an alternative.

For good performance of the integrated magnetometer, it is necessary to install the device at least 20 cm away from magnetized objects and cables powering servos/motors. In addition, please keep the device orientation respecting the flight direction as shown in the picture below (note the arrow on the device).

Mr. KAVAN CS: /* Registration and pairing */

<languages/>
<translate>

== Introduction ==
The '''KAVAN V15''' is a 24-channel RC kit using a 2.4GHz simultaneous dual-frequency transmission system with full telemetry support ('''Twin 2.4GHz'''). It boasts a superior response time of up to 4ms and a range of up to tens of kilometres. You can also choose '''ACCESS''' transmission system, also with telemetry. The V20 can therefore be paired with a wide range of KAVAN or FrSky receivers, telemetry or not, with classic PWM and S.BUS outputs. It is suitable for both advanced and sport pilots. Excellent for controlling various aircraft models or heli/multicopters. It can also be easily set up for ships or land models. To do this, use the wide range of functions and mixes available in the '''ETHOS''' operating system. You can conveniently adjust these to your own preferences on the large colour touchscreen.


If you have any questions about the V15 transmitter and its operation, please contact the technical and service staff at KAVAN Europe s.r.o. by e-mail ('''info@kavanrc.com''' for general technical information, '''service@kavanrc.com''' for service) or by phone ('''+420 466 260 133''' for general technical information, '''+420 463 358 700''' for service), during working hours 8 am–4 pm CET, Monday to Friday).

=== Navigation controllers ===
The left navigation buttons represent the MODEL/SYSTEM/DISPLAY/BACK functions. The right navigation knob is used to control the display and performs the same functions as the touch control.


=== Software ETHOS Suite ===
The ETHOS Suite can be used to update the transmitter‘s bootloader, firmware, SD card, flash, and also convert image and audio format. Find the latest information and download the ETHOS software at [https://ethos.frsky-rc.com/ www.ethos.frsky-rc.com].


{{Note|type=info|text='''Note:''' To use the ETHOS Suite app with the KAVAN transmitter without problems, always keep the transmitter bootloader on the latest version. Also, back up your current version before upgrading.}}

== Operating system ETHOS == 

=== Creating a model === 


# Open the Model Settings, open Model Selection and select the desired model.
# Configure and name the newly created model.


=== Model setting - internal RF module ===
Select the INT module. Switch on the internal module by switching the „Status“ slider to the „ON“ position. Select the internal or external antenna (two internal antennas and external antennas work simultaneously when selecting Antenna: External). Select the RF protocol according to your receiver type.


{{Note|type=info|text='''Note:''' Although the RF module has built-in protection, we advise to make sure that the external antennas are mounted before selecting Antenna: External. Note that the selection of the antenna type is made for each model separately, so each time you change the model selection, ETHOS will switch on the antenna mode set for that model.}}


==== Channel range ====
The built-in RF module supports up to 24 channels. The range is adjustable and must be checked before use. In the Channel Range menu, select the number of channels you will use for the model.

=== Registration and pairing === 


==== Protocols ACCESS and Twin 2.4GHz ====
Before you start using your transmitter, you must first register the desired receiver.


# Begin the registration process by selecting [Register].
# A window will appear with the message "Waiting...." with a repeating voice prompt "Register". Hold down the pairing button on the receiver and turn it on. Wait for the red and green LEDs to light up.
# The RID and UID can be set at this stage:
# Press the [Register] button to complete the setup. The "Registration OK" dialogue box will appear. Press the [OK] button to continue.
# Turn off the receiver. This registers the receiver. However, you still need to pair it with the transmitter to use it.


*'''RID:''' This is the unique identifier of the transmitter. It can be changed to the same/own code to use the Smart share feature for sharing models (if you want to share models and own multiple transmitters, or if you share models with other modellers, you must have the same RID set on those transmitters). The RID is the transmitter data (Owner Registration ID) written into the receiver‘s memory. If two transmitters have the same RID, you can easily share models, including receivers, between them using the Smart share function.
*'''RX name''': the naming of the receiver is done automatically when the receiver is paired for the first time. This name can be changed at any time. This is useful when using more than one receiver, e.g. to remember the settings of the receivers, e.g. '''RX4R1''' is for CH1–8 or '''RX4R2''' is for CH9–16 or '''RX4R3''' is for CH17–24.
*'''UID''': is used to distinguish multiple receivers used simultaneously in one model. A default value of 0 may be left for a single receiver. If more than one receiver is to be used in one model, the UID must be changed, usually '''0''' for CH1–8, '''1''' for CH9–16 and '''2''' for CH17–24. Note that this UID cannot be read back from the receiver, so it is a good idea to tag the receiver.


{{Note|type=error|text='''Caution:''' Do not pair with an electric motor connected or with a combustion engine running.}}


'''Pairing'''


Pairing a receiver allows the receiver registered in phase 1 to be paired with one of the transmitters. Thereafter, the receiver will only communicate with this transmitter unless you pair it with another transmitter. Before using the transmitter for the first time, you must check the range of the transmitter.


# Turn off the power to the receiver.
# RX 1 [Pairing]: Select [Pairing] to start the pairing process. Every few seconds, a „Pairing“ voice alert will sound to confirm that you are in pairing mode. A pop-up window will display the message "Waiting for receiver...".
# Turn on the receiver without holding the F/S pairing button. A window will appear with the message "Device selection" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A message will appear indicating that the pairing was successful.
# Switch off the transmitter and receiver.
# Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.


* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.
* If a redundant connection is required, repeat for receivers 2 and 3.


==== Protocol ACCST D16 ====
The ACCST D16 protocol does not use a registration system, but only a pairing system.


# Turn off power to the receiver.
# Selecting [Pairing], a pop-up window will appear with a selection of channels, once selected, start the pairing process. Every few seconds, a "Pairing" voice alert will sound to confirm that you are in pairing mode. The pop-up window will display the message "Pairing ...".
# Turn on the receiver while holding the pairing button F/S. A window will appear with the message "Select Device" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A window will appear with a message that the pairing was successful. Switch off the transmitter and receiver. Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.
* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.


=== Fail-safe emergency rates ===
When Fail-safe is enabled, 3 modes are available: No signal, Hold, Custom.


* '''No signal''': when signal is lost, the receiver does not send a control signal to the rates on any channel. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Hold''': the receiver maintains the rates as they were before the signal was lost. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Custom''': the receiver keeps the rate value on all channels as you preselect it. Select the Fail-safe setting menu. Switch from Disconnect/Hold/Not Set to „Custom“. Select the channel for which you want to set fail-safe rates and confirm the selection. Then set the rates on each desired channel and confirm the selection. Wait 9 seconds for the Fail-safe setting change to take effect.


{{Note|type=info|text='''Note:''' If the fail-safe rates are disabled on the transmitter, the fail-safe rates set on the receiver will automatically be used. The S.BUS connector does not support „Disconnect“ mode, and will always use „Hold“ or „Custom“ mode.}}


=== Range check ===
A pre-flight range check should be performed before each flight. Select the "RF System" section, select either the internal or external module, select "Action", then "Range Check" and confirm the selection. In range check mode, the effective range of the transmitter is reduced to 1/30. Press "Range Check" again to return to normal mode.


A "Range Check" voice alert will sound every few seconds to confirm that you are in range check mode. A pop-up window on the display will show the receiver UID and the VFR % and RSSI values to evaluate the reception quality. Under ideal conditions, when the transmitter and receiver are both 1 m above the ground, the Alarm should appear at a distance of approximately 30 m from each other.

== Conclusion == 


=== Principles of safe operation ===
Operating the models can be dangerous if you do not follow the appropriate safety guidelines. Here are some of the most important recommendations to help ensure safe operation.
* Before taking off, make sure the model responds properly to the gimbal movements on the transmitter. Also make sure all switches and other controls are functioning properly. If you find any problems, do not fly the model until all functions are working properly.
* Never fly in rain, strong winds or at night. Water can cause failure or improper operation and impair the control of the model, with the risk of a crash.


* Never turn off the power switch in flight when the model‘s engine is running or the battery is connected. In this case, control of the model will be impossible, and the model will crash. Even if you turn the switch back on, normal operation will not resume until the internal transmitter and receiver initialization processes are completed.
* Do not start the internal combustion engine or electric motor while wearing the neck strap. The strap can be caught by a spinning propeller, rotor, etc. and cause serious injury.
* Never fly in range check mode In this mode, the transmitter operates at reduced power and a crash could occur.
* Do not fly if you are physically or mentally indisposed, as this can be dangerous to yourself and others. Also, never fly under the influence of alcohol, narcotics or drugs affecting your senses.
* Do not fly near airports, near or over people, near residential buildings, schools, hospitals, or other places where people congregate, near high voltage power lines, tall buildings and structures, or communication facilities.
* If you place the transmitter on the ground in preparation for flight, do not place it in an upright position. The transmitter may tip over, the controls may become misaligned, and the propeller or rotor may spin unexpectedly and cause injury.
* Do not touch internal combustion engines, electric motors or controllers during or immediately after operation. These devices can become very hot during operation.
* For safety reasons, always fly with the model in line of sight at all times. Getting behind buildings or other large objects will not only cause you to lose sight of the model, but the obstruction will prevent the RF signal from the transmitter from propagating and cause you to lose control of the model.
* Always set fail-safe emergency rates for safety. Take special care to set the throttle to neutral in case of an emergency.
* Always check the charge level of the transmitter and receiver batteries before each takeoff. Low voltage will cause loss of control of the model and a crash.
* At the beginning of each flight day, check the operation of all control surfaces and perform a range check. If using the Trainer function, check that the model responds properly to both teacher and student transmitter controls. Even an incorrect setting of a single transmitter or model function can cause a crash.
* Before turning on the transmitter: 1. Always pull the throttle control all the way down (to neutral). 2. Turn the transmitter on first, then the receiver.
* Before turning off the transmitter after the internal combustion engine or electric motor has stopped (is in a condition where it cannot start again): 1. Turn off the receiver power switch. 2. Then turn off the transmitter power switch. If you turn the power on/off in reverse order, the propeller or rotor may spin unexpectedly and cause injury. Also, follow the above order when setting fail-safe emergency rates.
* When setting the transmitter, turn the engine off/shut down unless its operation is necessary for the setting. In the case of an electric motor, disconnect its cables. Use extra caution when setting the transmitter while the motor is running. Ensure that the model is properly secured and cannot come into contact with anyone or anything. An unexpected increase in RPM can cause serious injury.

Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.
* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.


=== Fail-safe emergency rates ===
When Fail-safe is enabled, 3 modes are available: No signal, Hold, Custom.


* '''No signal''': when signal is lost, the receiver does not send a control signal to the rates on any channel. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Hold''': the receiver maintains the rates as they were before the signal was lost. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Custom''': the receiver keeps the rate value on all channels as you preselect it. Select the Fail-safe setting menu. Switch from Disconnect/Hold/Not Set to „Custom“. Select the channel for which you want to set fail-safe rates and confirm the selection. Then set the rates on each desired channel and confirm the selection. Wait 9 seconds for the Fail-safe setting change to take effect.


{{Note|type=info|text='''Note:''' If the fail-safe rates are disabled on the transmitter, the fail-safe rates set on the receiver will automatically be used. The S.BUS connector does not support „Disconnect“ mode, and will always use „Hold“ or „Custom“ mode.}}


=== Range check ===
A pre-flight range check should be performed before each flight. Select the "RF System" section, select either the internal or external module, select "Action", then "Range Check" and confirm the selection. In range check mode, the effective range of the transmitter is reduced to 1/30. Press "Range Check" again to return to normal mode.


A "Range Check" voice alert will sound every few seconds to confirm that you are in range check mode. A pop-up window on the display will show the receiver UID and the VFR % and RSSI values to evaluate the reception quality. Under ideal conditions, when the transmitter and receiver are both 1 m above the ground, the Alarm should appear at a distance of approximately 30 m from each other.

== Conclusion == 


=== Principles of safe operation ===
Operating the models can be dangerous if you do not follow the appropriate safety guidelines. Here are some of the most important recommendations to help ensure safe operation.
* Before taking off, make sure the model responds properly to the gimbal movements on the transmitter. Also make sure all switches and other controls are functioning properly. If you find any problems, do not fly the model until all functions are working properly.
* Never fly in rain, strong winds or at night. Water can cause failure or improper operation and impair the control of the model, with the risk of a crash.


* Never turn off the power switch in flight when the model‘s engine is running or the battery is connected. In this case, control of the model will be impossible, and the model will crash. Even if you turn the switch back on, normal operation will not resume until the internal transmitter and receiver initialization processes are completed.
* Do not start the internal combustion engine or electric motor while wearing the neck strap. The strap can be caught by a spinning propeller, rotor, etc. and cause serious injury.
* Never fly in range check mode In this mode, the transmitter operates at reduced power and a crash could occur.
* Do not fly if you are physically or mentally indisposed, as this can be dangerous to yourself and others. Also, never fly under the influence of alcohol, narcotics or drugs affecting your senses.
* Do not fly near airports, near or over people, near residential buildings, schools, hospitals, or other places where people congregate, near high voltage power lines, tall buildings and structures, or communication facilities.
* If you place the transmitter on the ground in preparation for flight, do not place it in an upright position. The transmitter may tip over, the controls may become misaligned, and the propeller or rotor may spin unexpectedly and cause injury.
* Do not touch internal combustion engines, electric motors or controllers during or immediately after operation. These devices can become very hot during operation.
* For safety reasons, always fly with the model in line of sight at all times. Getting behind buildings or other large objects will not only cause you to lose sight of the model, but the obstruction will prevent the RF signal from the transmitter from propagating and cause you to lose control of the model.
* Always set fail-safe emergency rates for safety. Take special care to set the throttle to neutral in case of an emergency.
* Always check the charge level of the transmitter and receiver batteries before each takeoff. Low voltage will cause loss of control of the model and a crash.
* At the beginning of each flight day, check the operation of all control surfaces and perform a range check. If using the Trainer function, check that the model responds properly to both teacher and student transmitter controls. Even an incorrect setting of a single transmitter or model function can cause a crash.
* Before turning on the transmitter: 1. Always pull the throttle control all the way down (to neutral). 2. Turn the transmitter on first, then the receiver.
* Before turning off the transmitter after the internal combustion engine or electric motor has stopped (is in a condition where it cannot start again): 1. Turn off the receiver power switch. 2. Then turn off the transmitter power switch. If you turn the power on/off in reverse order, the propeller or rotor may spin unexpectedly and cause injury. Also, follow the above order when setting fail-safe emergency rates.
* When setting the transmitter, turn the engine off/shut down unless its operation is necessary for the setting. In the case of an electric motor, disconnect its cables. Use extra caution when setting the transmitter while the motor is running. Ensure that the model is properly secured and cannot come into contact with anyone or anything. An unexpected increase in RPM can cause serious injury.

=== Setting the gimbals ===
Unscrew the 4 screws on the back cover of the transmitter, remove the back cover. From here, you can adjust the rotation of the cross controllers up to 8°, or tune the return spring force and lock. After that loosen the screws, adjust the angle and retighten the screws.


==== Changing the mode ====
From the gimbal menu, change the current mode (mode 2 by default) to the desired mode. Turn off the transmitter, remove the battery case cover and disconnect and remove the battery. Unscrew the 4 screws of the transmitter back cover and remove it (pay extra attention to the attached antennas, they can be disconnected for better handling). To change to the desired mode, loosen the screw holding the self-centering arm mechanism, then screw it into the other gimbal.


You can also adjust the strength of the centering springs and ratchet, and possibly rotate the entire gimbal up to 8 degrees. Put on the back cover of the transmitter, screw in the 4 screws on the back of the transmitter, connect and insert the battery (making sure to maintain the correct polarity) and put the battery tray cover back on.


{{Note|type=error|text='''Caution:''' When using the USB charging function, charge the battery using a suitable USB adapter: voltage: 5±0.2 V; current: >2.0 A.}}


=== Charging the battery ===
The transmitter supports a 2S (7.4V) Li-ion battery and it is equipped with a balancer for charging 2S batteries via a USB-C interface. The size of the battery compartment is 69.5×38.5×20 mm (W×H×D).


==== LED ====
'''ON''': charging in progress | '''OFF''': charging complete | '''FLASHING''': charging error


=== Navigation controllers ===
The left navigation buttons represent the MODEL/SYSTEM/DISPLAY/BACK functions. The right navigation knob is used to control the display and performs the same functions as the touch control.


=== Software ETHOS Suite ===
The ETHOS Suite can be used to update the transmitter‘s bootloader, firmware, SD card, flash, and also convert image and audio format. Find the latest information and download the ETHOS software at [https://ethos.frsky-rc.com/ www.ethos.frsky-rc.com].


{{Note|type=info|text='''Note:''' To use the ETHOS Suite app with the KAVAN transmitter without problems, always keep the transmitter bootloader on the latest version. Also, back up your current version before upgrading.}}

== Operating system ETHOS == 

=== Creating a model === 


# Open the Model Settings, open Model Selection and select the desired model.
# Configure and name the newly created model.


=== Model setting - internal RF module ===
Select the INT module. Switch on the internal module by switching the „Status“ slider to the „ON“ position. Select the internal or external antenna (two internal antennas and external antennas work simultaneously when selecting Antenna: External). Select the RF protocol according to your receiver type.


{{Note|type=info|text='''Note:''' Although the RF module has built-in protection, we advise to make sure that the external antennas are mounted before selecting Antenna: External. Note that the selection of the antenna type is made for each model separately, so each time you change the model selection, ETHOS will switch on the antenna mode set for that model.}}


==== Channel range ====
The built-in RF module supports up to 24 channels. The range is adjustable and must be checked before use. In the Channel Range menu, select the number of channels you will use for the model.

=== Registration and pairing === 


==== Protocols ACCESS and Twin 2.4GHz ====
Before you start using your transmitter, you must first register the desired receiver.


# Begin the registration process by selecting [Register].
# A window will appear with the message "Waiting...." with a repeating voice prompt "Register". Hold down the pairing button on the receiver and turn it on. Wait for the red and green LEDs to light up.
# The RID and UID can be set at this stage:
# Press the [Register] button to complete the setup. The "Registration OK" dialogue box will appear. Press the [OK] button to continue.
# Turn off the receiver. This registers the receiver. However, you still need to pair it with the transmitter to use it.


*'''RID:''' This is the unique identifier of the transmitter. It can be changed to the same/own code to use the Smart share feature for sharing models (if you want to share models and own multiple transmitters, or if you share models with other modellers, you must have the same RID set on those transmitters). The RID is the transmitter data (Owner Registration ID) written into the receiver‘s memory. If two transmitters have the same RID, you can easily share models, including receivers, between them using the Smart share function.
*'''RX name''': the naming of the receiver is done automatically when the receiver is paired for the first time. This name can be changed at any time. This is useful when using more than one receiver, e.g. to remember the settings of the receivers, e.g. '''RX4R1''' is for CH1–8 or '''RX4R2''' is for CH9–16 or '''RX4R3''' is for CH17–24.
*'''UID''': is used to distinguish multiple receivers used simultaneously in one model. A default value of 0 may be left for a single receiver. If more than one receiver is to be used in one model, the UID must be changed, usually '''0''' for CH1–8, '''1''' for CH9–16 and '''2''' for CH17–24. Note that this UID cannot be read back from the receiver, so it is a good idea to tag the receiver.


{{Note|type=error|text='''Caution:''' Do not pair with an electric motor connected or with a combustion engine running.}}


'''Pairing'''


Pairing a receiver allows the receiver registered in phase 1 to be paired with one of the transmitters. Thereafter, the receiver will only communicate with this transmitter unless you pair it with another transmitter. Before using the transmitter for the first time, you must check the range of the transmitter.


# Turn off the power to the receiver.
# RX 1 [Pairing]: Select [Pairing] to start the pairing process. Every few seconds, a „Pairing“ voice alert will sound to confirm that you are in pairing mode. A pop-up window will display the message "Waiting for receiver...".
# Turn on the receiver without holding the F/S pairing button. A window will appear with the message "Device selection" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A message will appear indicating that the pairing was successful.
# Switch off the transmitter and receiver.
# Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.


* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.
* If a redundant connection is required, repeat for receivers 2 and 3.


==== Protocol ACCST D16 ====
The ACCST D16 protocol does not use a registration system, but only a pairing system.


# Turn off power to the receiver.
# Selecting [Pairing], a pop-up window will appear with a selection of channels, once selected, start the pairing process. Every few seconds, a "Pairing" voice alert will sound to confirm that you are in pairing mode. The pop-up window will display the message "Pairing ...".
# Turn on the receiver while holding the pairing button F/S. A window will appear with the message "Select Device" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A window will appear with a message that the pairing was successful. Switch off the transmitter and receiver. Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.
* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.

=== Setting the gimbals ===
Unscrew the 4 screws on the back cover of the transmitter, remove the back cover. From here, you can adjust the rotation of the cross controllers up to 8°, or tune the return spring force and lock. After that loosen the screws, adjust the angle and retighten the screws.


==== Changing the mode ====
From the gimbal menu, change the current mode (mode 2 by default) to the desired mode. Turn off the transmitter, remove the battery case cover and disconnect and remove the battery. Unscrew the 4 screws of the transmitter back cover and remove it (pay extra attention to the attached antennas, they can be disconnected for better handling). To change to the desired mode, loosen the screw holding the self-centering arm mechanism, then screw it into the other gimbal.


You can also adjust the strength of the centering springs and ratchet, and possibly rotate the entire gimbal up to 8 degrees. Put on the back cover of the transmitter, screw in the 4 screws on the back of the transmitter, connect and insert the battery (making sure to maintain the correct polarity) and put the battery tray cover back on.


{{Note|type=error|text='''Caution:''' When using the USB charging function, charge the battery using a suitable USB adapter: voltage: 5±0.2 V; current: >2.0 A.}}


=== Charging the battery ===

==== LED ====
'''ON''': charging in progress | '''OFF''': charging complete | '''FLASHING''': charging error


=== Navigation controllers ===
The left navigation buttons represent the MODEL/SYSTEM/DISPLAY/BACK functions. The right navigation knob is used to control the display and performs the same functions as the touch control.


=== Software ETHOS Suite ===
The ETHOS Suite can be used to update the transmitter‘s bootloader, firmware, SD card, flash, and also convert image and audio format. Find the latest information and download the ETHOS software at [https://ethos.frsky-rc.com/ www.ethos.frsky-rc.com].


{{Note|type=info|text='''Note:''' To use the ETHOS Suite app with the KAVAN transmitter without problems, always keep the transmitter bootloader on the latest version. Also, back up your current version before upgrading.}}

== Operating system ETHOS == 

=== Creating a model === 


# Open the Model Settings, open Model Selection and select the desired model.
# Configure and name the newly created model.


=== Model setting - internal RF module ===
Select the INT module. Switch on the internal module by switching the „Status“ slider to the „ON“ position. Select the internal or external antenna (two internal antennas and external antennas work simultaneously when selecting Antenna: External). Select the RF protocol according to your receiver type.


{{Note|type=info|text='''Note:''' Although the RF module has built-in protection, we advise to make sure that the external antennas are mounted before selecting Antenna: External. Note that the selection of the antenna type is made for each model separately, so each time you change the model selection, ETHOS will switch on the antenna mode set for that model.}}


==== Channel range ====
The built-in RF module supports up to 24 channels. The range is adjustable and must be checked before use. In the Channel Range menu, select the number of channels you will use for the model.

=== Registration and pairing === 


==== Protocols ACCESS and Twin 2.4GHz ====
Before you start using your transmitter, you must first register the desired receiver.


# Begin the registration process by selecting [Register].
# A window will appear with the message "Waiting...." with a repeating voice prompt "Register". Hold down the pairing button on the receiver and turn it on. Wait for the red and green LEDs to light up.
# The RID and UID can be set at this stage:
# Press the [Register] button to complete the setup. The "Registration OK" dialogue box will appear. Press the [OK] button to continue.
# Turn off the receiver. This registers the receiver. However, you still need to pair it with the transmitter to use it.


*'''RID:''' This is the unique identifier of the transmitter. It can be changed to the same/own code to use the Smart share feature for sharing models (if you want to share models and own multiple transmitters, or if you share models with other modellers, you must have the same RID set on those transmitters). The RID is the transmitter data (Owner Registration ID) written into the receiver‘s memory. If two transmitters have the same RID, you can easily share models including receivers between them using the Smart share function.
*'''RX name''': the naming of the receiver is done automatically when the receiver is paired for the first time. This name can be changed at any time. This is useful when using more than one receiver, e.g. to remember the settings of the receivers, e.g. '''RX4R1''' is for CH1–8 or '''RX4R2''' is for CH9–16 or '''RX4R3''' is for CH17–24.
*'''UID''': is used to distinguish multiple receivers used simultaneously in one model. A default value of 0 may be left for a single receiver. If more than one receiver is to be used in one model, the UID must be changed, usually '''0''' for CH1-8, '''1''' for CH9-16 and '''2''' for CH17-24. Note that this UID cannot be read back from the receiver, so it is a good idea to tag the receiver.


{{Note|type=error|text='''Caution:''' Do not pair with an electric motor connected or with a combustion engine running.}}


'''Pairing'''


Pairing a receiver allows the receiver registered in phase 1 to be paired with one of the transmitters. Thereafter, the receiver will only communicate with this transmitter unless you pair it with another transmitter. Before using the transmitter for the first time, you must check the range of the transmitter.


# Turn off the power to the receiver.
# RX 1 [Pairing]: Select [Pairing] to start the pairing process. Every few seconds, a „Pairing“ voice alert will sound to confirm that you are in pairing mode. A pop-up window will display the message "Waiting for receiver...".
# Turn on the receiver without holding the F/S pairing button. A window will appear with the message "Device selection" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A message will appear indicating that the pairing was successful.
# Switch off the transmitter and receiver.
# Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.


* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.
* If redundant connection is required, repeat for receivers 2 and 3.


==== Protocol ACCST D16 ====
The ACCST D16 protocol does not use a registration system, but only a pairing system.


# Turn off power to the receiver.
# Selecting [Pairing], a pop-up window will appear with a selection of channels, once selected, start the pairing process. Every few seconds, a "Pairing" voice alert will sound to confirm that you are in pairing mode. The pop-up window will display the message "Pairing ...".
# Turn on the receiver, while holding the pairing button F/S. A window will appear with the message "Select Device" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A window will appear with a message that the pairing was successful. Switch off the transmitter and receiver. Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.
* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.


=== Fail-safe emergency rates ===
When Fail-safe is enabled, 3 modes are available: No signal, Hold, Custom.


* '''No signal''': when signal is lost, the receiver does not send a control signal to the rates on any channel. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Hold''': the receiver maintains the rates as they were before the signal was lost. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Custom''': the receiver keeps the rate value on all channels as you preselect it. Select the Fail-safe setting menu. Switch from Disconnect/Hold/Not Set to „Custom“. Select the channel for which you want to set fail-safe rates and confirm the selection. Then set the rates on each desired channel and confirm the selection. Wait 9 seconds for the Fail-safe setting change to take effect.


{{Note|type=info|text='''Note:''' If the fail-safe rates are disabled on the transmitter, the fail-safe rates set on the receiver will automatically be used. The S.BUS connector does not support „Disconnect“ mode, and will always use „Hold“ or „Custom“ mode.}}


=== Range check ===
A pre-flight range check should be performed before each flight. Select the "RF System" section, select either the internal or external module, select "Action", then "Range Check" and confirm the selection. In range check mode, the effective range of the transmitter is reduced to 1/30. Press "Range Check" again to return to normal mode.


A "Range Check" voice alert will sound every few seconds to confirm that you are in range check mode. A pop-up window on the display will show the receiver UID and the VFR % and RSSI values to evaluate the reception quality. Under ideal conditions, when the transmitter and receiver are both 1 m above the ground, the Alarm should appear at a distance of approximately 30 m from each other.

== Conclusion == 


=== Principles of safe operation ===
Operating the models can be dangerous if you do not follow the appropriate safety guidelines. Here are some of the most important recommendations to help ensure safe operation.
* Before taking off, make sure the model responds properly to the gimbal movements on the transmitter. Also make sure all switches and other controls are functioning properly. If you find any problems, do not fly the model until all functions are working properly.
* Never fly in rain, strong winds or at night. Water can cause failure or improper operation and impair the control of the model, with the risk of a crash.


* Never turn off the power switch in flight when the model‘s engine is running or the battery is connected. In this case, control of the model will be impossible, and the model will crash. Even if you turn the switch back on, normal operation will not resume until the internal transmitter and receiver initialization processes are completed.
* Do not start the internal combustion engine or electric motor while wearing the neck strap. The strap can be caught by a spinning propeller, rotor, etc. and cause serious injury.
* Never fly in range check mode In this mode, the transmitter operates at reduced power and a crash could occur.
* Do not fly if you are physically or mentally indisposed, as this can be dangerous to yourself and others. Also, never fly under the influence of alcohol, narcotics or drugs affecting your senses.
* Do not fly near airports, near or over people, near residential buildings, schools, hospitals, or other places where people congregate, near high voltage power lines, tall buildings and structures, or communication facilities.
* If you place the transmitter on the ground in preparation for flight, do not place it in an upright position. The transmitter may tip over, the controls may become misaligned, and the propeller or rotor may spin unexpectedly and cause injury.
* Do not touch internal combustion engines, electric motors or controllers during or immediately after operation. These devices can become very hot during operation.
* For safety reasons, always fly with the model in line of sight at all times. Getting behind buildings or other large objects will not only cause you to lose sight of the model, but the obstruction will prevent the RF signal from the transmitter from propagating and cause you to lose control of the model.
* Always set fail-safe emergency rates for safety. Take special care to set the throttle to neutral in case of an emergency.
* Always check the charge level of the transmitter and receiver batteries before each takeoff. Low voltage will cause loss of control of the model and a crash.
* At the beginning of each flight day, check the operation of all control surfaces and perform a range check. If using the Trainer function, check that the model responds properly to both teacher and student transmitter controls. Even an incorrect setting of a single transmitter or model function can cause a crash.
* Before turning on the transmitter: 1. Always pull the throttle control all the way down (to neutral). 2. Turn the transmitter on first, then the receiver.
* Before turning off the transmitter after the internal combustion engine or electric motor has stopped (is in a condition where it cannot start again): 1. Turn off the receiver power switch. 2. Then turn off the transmitter power switch. If you turn the power on/off in reverse order, the propeller or rotor may spin unexpectedly and cause injury. Also, follow the above order when setting fail-safe emergency rates.
* When setting the transmitter, turn the engine off/shut down unless its operation is necessary for the setting. In the case of an electric motor, disconnect its cables. Use extra caution when setting the transmitter while the motor is running. Ensure that the model is properly secured and cannot come into contact with anyone or anything. An unexpected increase in RPM can cause serious injury.

The left navigation buttons represent the MODEL/SYSTEM/DISPLAY/BACK functions. The right navigation knob is used to control the display and performs the same functions as the touch control.


=== Software ETHOS Suite ===
The ETHOS Suite can be used to update the transmitter‘s bootloader, firmware, SD card, flash, and also convert image and audio format. Find the latest information and download the ETHOS software at [https://ethos.frsky-rc.com/ www.ethos.frsky-rc.com].


{{Note|type=info|text='''Note:''' To use the ETHOS Suite app with the KAVAN transmitter without problems, always keep the transmitter bootloader on the latest version. Also, back up your current version before upgrading.}}

== Operating system ETHOS == 

=== Creating a model === 


# Open the Model Settings, open Model Selection and select the desired model.
# Configure and name the newly created model.


=== Model setting - internal RF module ===
Select the INT module. Switch on the internal module by switching the „Status“ slider to the „ON“ position. Select the internal or external antenna (two internal antennas and external antennas work simultaneously when selecting Antenna: External). Select the RF protocol according to your receiver type.


{{Note|type=info|text='''Note:''' Although the RF module has built-in protection, we advise to make sure that the external antennas are mounted before selecting Antenna: External. Note that the selection of the antenna type is made for each model separately, so each time you change the model selection, ETHOS will switch on the antenna mode set for that model.}}


==== Channel range ====
The built-in RF module supports up to 24 channels. The range is adjustable and must be checked before use. In the Channel Range menu, select the number of channels you will use for the model.

=== Registration and pairing === 


==== Protocols ACCESS and Twin 2.4GHz ====
Before you start using your transmitter, you must first register the desired receiver.


# Begin the registration process by selecting [Register].
# A window will appear with the message "Waiting...." with a repeating voice prompt "Register". Hold down the pairing button on the receiver and turn it on. Wait for the red and green LEDs to light up.
# The RID and UID can be set at this stage:
# Press the [Register] button to complete the setup. The "Registration OK" dialogue box will appear. Press the [OK] button to continue.
# Turn off the receiver. This registers the receiver. However, you still need to pair it with the transmitter to use it.


*'''RID:''' This is the unique identifier of the transmitter. It can be changed to the same/own code to use the Smart share feature for sharing models (if you want to share models and own multiple transmitters, or if you share models with other modellers, you must have the same RID set on those transmitters). The RID is the transmitter data (Owner Registration ID) written into the receiver‘s memory. If two transmitters have the same RID, you can easily share models including receivers between them using the Smart share function.
*'''RX name''': the naming of the receiver is done automatically when the receiver is paired for the first time. This name can be changed at any time. This is useful when using more than one receiver, e.g. to remember the settings of the receivers, e.g. '''RX4R1''' is for CH1–8 or '''RX4R2''' is for CH9–16 or '''RX4R3''' is for CH17–24.
*'''UID''': is used to distinguish multiple receivers used simultaneously in one model. A default value of 0 may be left for a single receiver. If more than one receiver is to be used in one model, the UID must be changed, usually '''0''' for CH1-8, '''1''' for CH9-16 and '''2''' for CH17-24. Note that this UID cannot be read back from the receiver, so it is a good idea to tag the receiver.


{{Note|type=error|text='''Caution:''' Do not pair with an electric motor connected or with a combustion engine running.}}


'''Pairing'''


Pairing a receiver allows the receiver registered in phase 1 to be paired with one of the transmitters. Thereafter, the receiver will only communicate with this transmitter unless you pair it with another transmitter. Before using the transmitter for the first time, you must check the range of the transmitter.


# Turn off the power to the receiver.
# RX 1 [Pairing]: Select [Pairing] to start the pairing process. Every few seconds, a „Pairing“ voice alert will sound to confirm that you are in pairing mode. A pop-up window will display the message "Waiting for receiver...".
# Turn on the receiver without holding the F/S pairing button. A window will appear with the message "Device selection" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A message will appear indicating that the pairing was successful.
# Switch off the transmitter and receiver.
# Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.


* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.
* If redundant connection is required, repeat for receivers 2 and 3.


==== Protocol ACCST D16 ====
The ACCST D16 protocol does not use a registration system, but only a pairing system.


# Turn off power to the receiver.
# Selecting [Pairing], a pop-up window will appear with a selection of channels, once selected, start the pairing process. Every few seconds, a "Pairing" voice alert will sound to confirm that you are in pairing mode. The pop-up window will display the message "Pairing ...".
# Turn on the receiver, while holding the pairing button F/S. A window will appear with the message "Select Device" and the name of the receiver you just turned on.
# Scroll to the receiver name and select it. A window will appear with a message that the pairing was successful. Switch off the transmitter and receiver. Switch on the transmitter and then the receiver. If the green LED on the receiver is lit and the red LED is not lit, the receiver is connected to the transmitter. The pairing of the receiver and transmitter will not need to be repeated unless one is replaced.
* The receiver will only be controlled by the transmitter it is paired to. Other transmitters in its vicinity will not affect its operation.
* The name of the RX1 receiver will now be displayed next to the selected receiver.
* The receiver is now ready for use.


=== Fail-safe emergency rates ===
When Fail-safe is enabled, 3 modes are available: No signal, Hold, Custom.


* '''No signal''': when signal is lost, the receiver does not send a control signal to the rates on any channel. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Hold''': the receiver maintains the rates as they were before the signal was lost. To use this type, select it from the menu and wait 9 seconds for the Fail-safe setting change to take effect.
* '''Custom''': the receiver keeps the rate value on all channels as you preselect it. Select the Fail-safe setting menu. Switch from Disconnect/Hold/Not Set to „Custom“. Select the channel for which you want to set fail-safe rates and confirm the selection. Then set the rates on each desired channel and confirm the selection. Wait 9 seconds for the Fail-safe setting change to take effect.


{{Note|type=info|text='''Note:''' If the fail-safe rates are disabled on the transmitter, the fail-safe rates set on the receiver will automatically be used. The S.BUS connector does not support „Disconnect“ mode, and will always use „Hold“ or „Custom“ mode.}}


=== Range check ===
A pre-flight range check should be performed before each flight. Select the "RF System" section, select either the internal or external module, select "Action", then "Range Check" and confirm the selection. In range check mode, the effective range of the transmitter is reduced to 1/30. Press "Range Check" again to return to normal mode.


A "Range Check" voice alert will sound every few seconds to confirm that you are in range check mode. A pop-up window on the display will show the receiver UID and the VFR % and RSSI values to evaluate the reception quality. Under ideal conditions, when the transmitter and receiver are both 1 m above the ground, the Alarm should appear at a distance of approximately 30 m from each other.

== Conclusion == 


=== Principles of safe operation ===
Operating the models can be dangerous if you do not follow the appropriate safety guidelines. Here are some of the most important recommendations to help ensure safe operation.
* Before taking off, make sure the model responds properly to the gimbal movements on the transmitter. Also make sure all switches and other controls are functioning properly. If you find any problems, do not fly the model until all functions are working properly.
* Never fly in rain, strong winds or at night. Water can cause failure or improper operation and impair the control of the model, with the risk of a crash.


* Never turn off the power switch in flight when the model‘s engine is running or the battery is connected. In this case, control of the model will be impossible, and the model will crash. Even if you turn the switch back on, normal operation will not resume until the internal transmitter and receiver initialization processes are completed.
* Do not start the internal combustion engine or electric motor while wearing the neck strap. The strap can be caught by a spinning propeller, rotor, etc. and cause serious injury.
* Never fly in range check mode In this mode, the transmitter operates at reduced power and a crash could occur.
* Do not fly if you are physically or mentally indisposed, as this can be dangerous to yourself and others. Also, never fly under the influence of alcohol, narcotics or drugs affecting your senses.
* Do not fly near airports, near or over people, near residential buildings, schools, hospitals, or other places where people congregate, near high voltage power lines, tall buildings and structures, or communication facilities.
* If you place the transmitter on the ground in preparation for flight, do not place it in an upright position. The transmitter may tip over, the controls may become misaligned, and the propeller or rotor may spin unexpectedly and cause injury.
* Do not touch internal combustion engines, electric motors or controllers during or immediately after operation. These devices can become very hot during operation.
* For safety reasons, always fly with the model in line of sight at all times. Getting behind buildings or other large objects will not only cause you to lose sight of the model, but the obstruction will prevent the RF signal from the transmitter from propagating and cause you to lose control of the model.
* Always set fail-safe emergency rates for safety. Take special care to set the throttle to neutral in case of an emergency.
* Always check the charge level of the transmitter and receiver batteries before each takeoff. Low voltage will cause loss of control of the model and a crash.
* At the beginning of each flight day, check the operation of all control surfaces and perform a range check. If using the Trainer function, check that the model responds properly to both teacher and student transmitter controls. Even an incorrect setting of a single transmitter or model function can cause a crash.
* Before turning on the transmitter: 1. Always pull the throttle control all the way down (to neutral). 2. Turn the transmitter on first, then the receiver.
* Before turning off the transmitter after the internal combustion engine or electric motor has stopped (is in a condition where it cannot start again): 1. Turn off the receiver power switch. 2. Then turn off the transmitter power switch. If you turn the power on/off in reverse order, the propeller or rotor may spin unexpectedly and cause injury. Also, follow the above order when setting fail-safe emergency rates.
* When setting the transmitter, turn the engine off/shut down unless its operation is necessary for the setting. In the case of an electric motor, disconnect its cables. Use extra caution when setting the transmitter while the motor is running. Ensure that the model is properly secured and cannot come into contact with anyone or anything. An unexpected increase in RPM can cause serious injury.
