The SPEKTRUM AR7200BX / AR7210BX / AR7300BX does not finish initialization. What can I do?

Watch the running LED lights during the init phase: If the lights A - G light up the sensor's rest positions are being calibrated, H - N show determining the RC channels and their center positions.

AR7200BX / AR7300BX: Initially the chase is from A - N. If one step is done the indication light for this step will quit running.
AR7210BX: Initially the chase is from H - N (Stick calibration). Only if this step is finished the chase from A - G (Sensor calibration) will start.

When LEDs A - G do not quit running

• The sensors register movement and calibration of rest position can not be finished. Make sure the unit/the helicopter does not get moved e.g. by wind gusts or people leaning on your work bench where the heli is standing on.
• Sensors damaged. Return the device for repair.
• Power supply voltage is dropping due to weak power supply or damaged servos.
  

When LEDs H - N do not quit running

• Is the transmitter switched on?
• Check whether your transmitter is correctly bound to the system.
• Keep at least 1m/3ft distance between transmitter and receiver
