Place the transmitter and the receiver close to each other (within one meter).
Turn your transmitter ON and then your receiver.
There is a black binding button on the side of the R8EF receiver; press and hold the receiver binding button for about 2 seconds until the LED starts to blink on the receiver. After about 8 blinks the process is accomplished and the receiver LED will glow red steady.
Turn the receiver off and then on again. Check the correct operation of all servos.
