Teaching the sound unit for throttle idle/accelerate point:
1. Power on transmitter and receiver. LED blinks fast -> normal mode. Bring throttle stick to idle. Motor must not move.
2. Bridge study switch for about 0.5 seconds until beep -> LED cont. on.
At this moment the idle position of the throttle stick is stored.
3. Move throttle stick to your desired acceleration point (throttle stick position where idle dead band stops and engine running sound starts) and wait for a beep. Now the dead (neutral) band of the speed channel is defined.
4. Move the throttle stick to full speed position and wait for three beeps. After this the sound unit is back in the normal operation mode.
