3) Turn your transmitter on while holding the F/S button on the transmitter module . Release it in a few seconds. The RED
LED on the transmitter module will flash, indicating the transmitter is ready to bind to the receiver.
4) Connect the battery to the receiver while holding the F/S button on the receiver. The RED LED on the receiver will flash,
indicating the binding process is completed. Turn off both the transmitter and receiver.
5) Turn on the transmitter and re-connect the battery to the receiver. The RED SOLID LED on the receiver will indicate the
receiver is receiving commands from the transmitter. The receiver/transmitter binding will not have to be repeated
unless one of the two is replaced.
After the above steps are completed, both the transmitter and the receiver are ready to be used.
