TQ 2.4GHz Binding Instructions
For proper operation, the transmitter and receiver must be electronically 'bound.' This has been
done for you at the factory. Should you ever need to re-bind the system or bind to an additional
transmitter or receiver, follow these instructions.
1. Press and hold the SET button on the transmitter.
2. Turn on the transmitter and release the SET button. The status LED will flash red slowly, indicating
that the transmitter is in bind mode.
3. Press and hold the LINK button on the receiver.
4. Turn on the vehicle and release the LINK button. The LED on the receiver will flash red, indicating that
the receiver is in bind mode.
5. When the LEDs on both the transmitter and the receiver turn solid green, the system is bound and
ready for use. Confirm that the steering and throttle operate properly before driving your model.
