=== Introduction ===
Congratulations on your purchase of the '''KAVAN R10''' advanced 10-channel telemetry receiver. It operates on a 2.4GHz simultaneous dual-frequency transmission system '''Twin 2.4GHz'''. It has 10 high-precision PWM channels and 16 or 24-channel modes using S.BUS. Two detachable antennas with IPEX4 connectors provide full signal strength over a range of up to tens of kilometres. It is especially ideal for gliders, but you can also use it for other various models. With redundancy support, it can be connected as a primary receiver via S.BUS. With the '''Twin 2.4GHz''' protocol, both receivers work fully simultaneously in this connection. Thanks to the F.BUS connection option, you can also pair it quickly and easily to several different telemetry devices, providing bidirectional data transmission via a single cable.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
It features advanced interference suppression for reliable, stable signal transmission across the entire range. Smart transmission system matching speeds up pairing. The black box function stores essential flight data. Receiver operating statuses are indicated by an LED indicator. Smart pairing allows firmware updates wirelessly.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
It is also available in a stabilised version offering ADV-enhanced stabilisation features. The ADV stabiliser offers an advanced mode with multiple programmable stabilised channels and flexibility.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
The classic stabilisation mode has been expanded with 5 additional stabilisation channels that provide pin mapping for each channel in several flight modes such as Stabilise, Auto-Level, Hover and Knife-Edge with model aircraft.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
The Advanced Stabilisation feature includes high-precision telemetry sensors to monitor altitude, vertical speed, etc.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
In Advanced Stabilisation mode, all output pins are configurable for stabilisation and other advanced features such as Stab file sharing, programmable parameters, developer access, etc.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">

=== Registration and pairing ===
Before using your receiver you must first register it.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
Procedure:
# Start the registration process by selecting '''[Register]'''.
# A window will appear with the message "Waiting...." and a repeating voice message "Register".
# Hold down the pairing button on the receiver and switch it on. Wait for the red and green LEDs to light up. The RID and UID can be set at this stage:
#* '''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 model sharing (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 can 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.
# Press the '''[Register]''' button to complete the settings. The "Registration OK" dialog 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.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{Note|type=error|'''Warning:''' Do not pair with an electric motor connected or with an internal combustion engine running.}}
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
==== Pairing ====
Receiver pairing allows a receiver registered in phase 1 to be paired with one of the transmitters. After that, the receiver will only communicate with that transmitter unless you pair it with another transmitter. Before using the transmitter for the first time, you must check the range of the transmitter!
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
# 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...".
# Switch on the receiver without holding the F/S pairing button. A window will appear with the message "Selecting Device" and the name of the receiver you have just switched on.
# Scroll to the receiver name and select it. A window will appear with a message that the pairing was successful.
# Turn 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 do not affect its function.
* The name of the selected RX1 receiver will now be displayed next to it.
* The receiver is now ready for use.
* If redundant wiring is required, repeat for receivers 2 and 3.

<div lang="en" dir="ltr" class="mw-content-ltr">
'''Stabilisation:''' When the model is activated, R10 Stabi will compensate for external forces (wind) as soon as it receives commands from the transmitter. This function is used to enhance the stability of the model on three axes (Pitch, Roll, YAW). CH13 could be used to adjust gyro gain by assigning a knob or a slider, changing the sensitivity of the counteracting signal produced by the internal three-axis gyroscope.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">

<div lang="en" dir="ltr" class="mw-content-ltr">
'''Hover:''' When the mode is activated, R10 Stabi will make the nose of the model straight up with an internal three-axis accelerometer and three-axis gyroscope on RUD and ELE channels (ELE and RUD inputs are not required). Under this mode, AIL is used to control the rotation of the model and THR to adjust the altitude. AIL channel works in stabilisation mode only.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''Knife-edge mode:''' When the mode is activated, R10 Stabi will roll the plane on a certain side (wing points up) with an internal three-axis accelerometer and three-axis gyroscope on RUD and AIL channels. Thus, AIL inputs are not required. While the mode steering is done with ELE, altitude will be maintained with THR/RUD. ELE channel operates in stabilisation mode only.

=== Fail-safe emergency rates ===
After enabling Fail-safe, there are 3 modes available: No signal, Hold, and Custom.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''No signal:''' When the signal is lost, the receiver does not send a control signal to the deflectors 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.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''Hold:''' The receiver maintains the deflections 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.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
'''Custom:''' The receiver maintains the deflection value on all channels as you pre-select 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 deflections and confirm the selection. Then set the deflections on each desired channel and confirm the selection. Wait 9 seconds for the Fail-safe setting change to take effect.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
{{Note|type=info|'''Note:'''
* If the failsafe is not set, the model will always work with the last working status before the signal is lost. That could cause potential damage.
* When the failsafe is disabled on the RF module side, the receiver defaults to Hold mode.
* When in No Signal Mode, do not set the Failsafe to No Signal Mode for the SBUS port as it will keep the signal output continuous. Set "Hold" or "Custom" mode for the SBUS port.}}
