Installation & Operation

The engine sound automatically starts when the throttle channel is first moved after powering on
If the engine remains idle for more than 20 seconds, the sound automatically shuts off
Moving the throttle again will restart the engine sound

Neutral Point Setup

Connect the speaker, ESC, and receiver.
Turn on the transmitter and power the receiver.
Short the indicated contacts using tweezers or conductive material.
A beep sound confirms the neutral point is recorded.
Push the throttle briefly to the start/idle point – another beep confirms the setting.
Push throttle to maximum – three beeps confirm setup completion.
