1) Go to the binding menu on the radio. Make sure it's set to FHSS-2.
2) With the system off, hold down the bind button on the receiver.
3) Engage the binding thing on the transmitter.
4) While holding down the bind button on the receiver, turn the system on.
5) Press the bind button on the transmitter again.
