Binding Procedure
1. Make sure the transmitter and vehicle are both powered off.
2. Install a bind plug in the receiver battery/bind port. You do not need to remove any of the other plugs to re-bind.
3. With the Bind plug installed, turn on the vehicle. Notice a blinking Orange LED within the receiver.
4. With the steering and throttle in the desired preset failsafe positions (neutral), press and hold the bind button and turn on the transmitter.
The red LED on the front of the transmitter will fl ash within a couple seconds, indicating the transmitter is in bind mode. Once the red LED
begins fl ashing, release the bind button.
5. When the receiver binds to the transmitter, the receiver light will turn solid.
6. Power off the vehicle and the transmitter.
7. Disconnect the battery from the ESC. Remove the bind plug from the receiver.
8. Safely store the bind plug (some owners attach the bind plug to their transmitter using two-part loops and clips).
9. The receiver will keep the binding to the transmitter until another binding is done.
If you encounter problems, obey binding instructions and refer to the transmitter troubleshooting guide for other instructions. If needed, contact the
appropriate Horizon Product Support offi ce.
