5. Maintenance

Keep the remote control and receiver clean and free from dust and moisture.
Avoid exposing the device to extreme temperatures or direct sunlight.
Remove batteries if the device will not be used for an extended period to prevent leakage.
Use a soft, dry cloth for cleaning. Do not use harsh chemicals or solvents.
Ensure the USB-C port is free from debris when charging or connecting for simulation.

6. Troubleshooting

6.1 Loss of Control Protection

This feature helps prevent your model from running away if the signal is lost.

Setting Method:

First, successfully align the transmitter with the receiver (bind).
Turn off the remote control first.
Press and hold the `Lower Fine Adjustment` button first, and then turn on the power switch of the remote control. The remote control light will sound a prompt, and the receiver light will flash quickly at the same time, indicating entering the setting state.
At this point, the throttle channel can be set for runaway protection function.
After the settings are completed, press the `Lower Fine Adjustment` button to exit.

Note: The default factory value for throttle channel runaway protection is the lowest or center point. Please do not use the protection value for out of control function without special usage requirements.

6.2 Locking Function

This function prevents accidental changes to settings.
