4.2 Binding/Pairing with RC Car
To establish communication between the transmitter and your RC car, a binding process is required. Refer to your specific HBX RC car model's manual (18858, 18859, or 18859A) for detailed binding instructions, as the procedure may vary slightly per receiver. Generally, the steps involve:
- Ensure both the transmitter and the RC car's receiver are powered off.
- Turn on the RC car's receiver (or connect its battery). The receiver's LED should blink, indicating it's in binding mode.
- While holding the bind button (if present on the transmitter, otherwise just power on), turn on the transmitter.
- The LED on both the transmitter and receiver should become solid, indicating a successful bind.
- Turn off both devices and then turn them on again in sequence (transmitter first, then car) to confirm the bind.
5. Instruccions de funcionament
5.1 Controlsview
Familiarize yourself with the main controls of the LS103 transmitter:
- Volant: Controls the left and right steering of the RC car. Turn clockwise for right, counter-clockwise for left.
- Activador de l'accelerador: Pull the trigger towards you to accelerate forward. Push the trigger away from you to brake or reverse.
- Interruptor ON / OFF: Encén o apaga el transmissor.
- Dial d'ajust de la direcció: Adjusts the neutral position of the steering. If the car pulls to one side when the steering wheel is centered, use this dial to correct it.
- Dial de compensació de l'accelerador: Adjusts the neutral position of the throttle. If the car moves slightly forward or backward when the throttle trigger is released, use this dial to correct it.
