TRAXXAS TQ RADIO SYSTEM
TQ 2.4GHz Binding Instructions
For proper operation, the transmitter and ECM 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 a different transmitter or ECM,
follow these instructions.
Note
: The transmitter and ECM must be
within 5 feet of each other.
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 EZ-Set button on the ECM as you plug in the
battery; release the EZ-Set button once the status LED flashes red.
4. The status LED will flash red slowly, indicating that the ECM is in bind
mode.
5. When the LEDs on both the transmitter and the ECM turn solid
green, the system is bound and ready for use. Confirm that the
steering and throttle operate properly before driving your model.
