Press and hold the BND button on the receiver. Connect power to the receiver while continuing to hold the BND button. The LED on the receiver will begin to blink rapidly, indicating that it has entered binding mode. Turn on the transmitter into binding mode:

Make sure all switches on the transmitter are in the down (or off) position and the throttle is at minimum.
