  • How to test it is functioning properly:
  • If you cannot find your Model, Simply turn off the Transmitter or do not move the control stick of the servo the LMA is connected to for 1 min, then you will hear a continuous beep sound.
  • If you ignore the continuous beep sound for around 2 minutes, the beep sound will change to a louder V sound.
  • By tracking the sound, you will be able to locate your RC plane / Helicopter

Mr John Davies from East Yorkshire has reported that they do not work with all R/C Systems, He has tried them with SPEKTRUM 7010 & 7610 Receivers and they do not operate correctly in that they continue to bleep after One Minute has elapsed. This is normal as it acts as alarm when the receiver is left on without being used, and so preventing an RX being left on by mistake !
