QHow to bind R8FM to transmitter?

A:

1. Put the transmitter and the receiver close to each other (about 50 centimeters) and power both on.
2. Switch on the transmitter and the LED of R8FM will start flashing slowly.

3. There is a black binding button (ID SET) on the side of receiver. Press the button for more than 1 second and release, the LED will flash quickly, meaning binding process is ongoing.

4. When the LED stops flashing and is always on, binding is complete and there will be a signal tower shown on top of the screen of the transmitter. If not succeed, repeat the above steps.

Note: If bind to transmitters without screen like T8S or T8FB, the always on LED means binding completed.

 

 

 

 

 

 

 

QWhy the LED of R8FM keeps flashing slowly?

A:The slow flashing LED means binding doesn’t succeed or the signal gets lost after binding completes.
