=== Introduction ===
Congratulations on purchasing the '''KAVAN Smart PRO AMS Alti motor switch''', a versatile device suitable for several competition categories where the altitude or motor run is limited. It can also be used as a standalone telemetric variometer. The sensor is usually connected between the receiver throttle channel and the appropriate signal input of the electronic speed controller.
The AMS contains a sensitive barometric altimeter/variometer that uses the latest MEMS technology to achieve a high accuracy level while preserving miniature dimensions. The sensor is able to detect tiny changes in atmospheric pressure to indicate the altitude change with a resolution of 0.1 metres. Using the integrated high-power cables, you can directly power the receiver and servos through the AMS from a BEC circuit of the speed controller.

=== Installation ===
Connect the AMS between the receiver and the electronic speed controller. To control the motor, select the appropriate channel on the receiver. Note that the sensor has high sensitivity to changes in atmospheric pressure and mechanical stress. Try to avoid any mechanical stress on the sensor. To achieve the most accurate altitude measurement, pay attention to the placement of the sensor. The device should not be exposed to direct airflow and close contact with heat-emitting objects (e.g. motors or speed controllers).
As an additional function, the telemetry output can be used for setting or wireless data reading. Connect an extension cable with JR connectors between the telemetry port of the receiver and the “Data” port on the sensor.

=== Competition flight ===
* Switch on the transmitter and pull the throttle to the off position. The pulse on the throttle channel must be shorter than 1.2 ms.
* Switch on the receiver (e.g. by connecting the flight battery pack).
* The AMS initializes the zero initial height for approximately 3 s after startup (indicated by the LED). During this time it does not accept any commands to start the motor.
* After initialization the LED turns off and you can fly. After starting the motor (pulse above 1.2 ms), the automatic countdown starts. The engine shuts down in any of the following cases:
** The pilot pulls the throttle below the decision level.
** The configured motor running time (F5J = 30 s) after start has elapsed.
** The model exceeds the configured shutdown altitude (altitude limiter mode).
* The motor can be restarted during flight if the appropriate option in the menu is configured. However, if the engine is restarted, all the data from the previous flight are discarded and the AMS shows “---.-m” for the rest of the flight. The new flight attempt can be entered after turning the altimeter off and back on.

=== Telemetry and settings ===
The device is compatible with JETIBOX and SMART BOX for programming. The JETIBOX menu is divided into three sections:
* '''Actual values''' – displays the latest telemetry values (altitude, vario, pressure, temperature) including minimums and maximums.
** '''Reset Min/Max''' - simultaneously press the Left and Right buttons to reset all minimums and maximums.
* '''Settings''' – basic settings of the sensor
** '''Language''' – choose the language of the JETIBOX screen.
** '''Device Mode''' – select the competition type in a single step:
*** Vario - the competition features (altitude/motor switch) are disabled and the sensor acts as a standard telemetry sensor. Motor input is copied to the output without any change.
*** '''F5J Logger''' - the training mode for the F5J category. The sensor limits the motor runtime (30 s) and records the “Start Height” as it is defined in the FAI F5J rules. All telemetry functions remain active in this mode. For a competition flight, activate a special F5J firmware with fixed settings and disabled telemetry.
*** '''ALES Limiter''' - the altitude and motor switch functions are active. You can specify the shutdown altitude and time according to local rules. All telemetry functions remain active and if needed, they may be disabled simply by disconnecting the telemetry cable from the “Data” port.
*** '''RC-E7 Limiter''' – a competition category originated in Austria. The shutdown altitude is fixed to 120 m and the maximum motor time is set to 240 s. During this period, the motor can be turned on and off arbitrarily. After 240 s it is no longer possible to turn on the motor.
** '''Shutdown Altitude''' – specify the cut-off altitude for the motor (ALES only).
** '''Shutdown Time''' – specify the maximum running time for the motor (ALES only, F5J applies a fixed value of 30 s).
** '''Allow Restart''' - enabling this option will allow you to turn on the motor more than once during the flight (ALES and F5J training).
*** '''Not allow''' – motor restart isn't possible during the flight. A new flight is available after the power cycle.
*** '''Emergency only''' – in this case, if you experience a critical situation, such as long distances at a low altitude, you can save your model by running the motor and raising the altitude. However, all the recorded flight data (“Start Height” and motor running time) will be discarded.
*** '''Auto Reinitialization/8m''' – motor restart is allowed if the model altitude is below 8 m (26 ft). Restarting the motor also immediately reinitiates a new competition flight. This mode is useful in case of training - after landing you can start a new round immediately without the need to power cycle the receiver/AMS.
** '''Throttle Idle''' – you can set the signal threshold where the motor stops.
** '''Vario Sensitivity''' – sets the amount of filtering for the pressure sensor data. By increasing the sensitivity you will get a faster response to altitude changes. Please note that the indicated noise may be increased as well. (Default value: Medium)
** '''Sink Rate''' – the rate of an aeroplane's descent when there aren't thermal effects. The value of the sink rate is added to the climb rate. This will result in locating thermal streams more precisely. Example: When the model flies at its nominal sink rate of 0.5 m/s, the vario is silent. As soon as the model enters any thermal upstream, the vario will start beeping (although the aeroplane may still be descending).
** '''Sealevel Pressure''' – the sea level pressure is used as a reference to calculate the absolute altitude. To calculate the altitude most accurately, set the pressure at your location adjusted to the sea level. The International Standard Atmosphere Model defines the sea level pressure as 1013 hPa (Vario mode only).
** '''Round Altitude''' – permits or denies rounding the altitude values displayed on the transmitter. Relative and absolute altitude round to full meters, the decimal part is omitted.
** '''Altitude Alarm''' – you can set a high altitude alarm. '''*)'''
** '''Vario Alarm''' – you can set an alarm for excessive climb or sink rate. '''*)'''
** '''Alarm Interval''' – sets the time between alarm announcements.
* '''Service''' – In this menu you can view the device version and reset it to the default factory configuration.
** '''Boot Mode''' – allows you to select one of the following firmware contained in the device:
*** '''Default''' – firmware with all options unlocked. It can be used for general purpose or training flights.
*** '''F5J Contest/F''' – a special mode for F5J first-class competition events (typically world championships or World Cup events). Motor restart is not allowed.
*** '''F5J Contest/S''' – a special mode for F5J second-class competition events (national or local events). Emergency motor restart is enabled. However, the competition flight is invalidated when the motor is restarted.
*** '''ERES Contest (F3-ERES)''' – altitude is limited to the value specified by the pilot. Maximum motor time is set to 30 s without the possibility of restarting.
** '''If you change any settings in the competition firmware, you have to restart the device to perform the next flight with the settings applied correctly.'''
