- Insert two 1.5V AA batteries (not included) into the compartment, observing the correct polarity (+/-).
- Close the battery cover securely.
5.4 Pairing the Remote Control
- Turn on the RC truck by pressing the power button. The LED on the truck will blink.
- Turn on the remote control. The indicator light on the remote will also blink.
- Wait a few seconds for the remote control and the truck to automatically pair. The indicator lights on both devices will become solid when successfully paired.
- If pairing fails, turn off both devices and repeat the process.
6. Operating Instructions
6.1 Basic Controls
- Steering Wheel: Turn left or right to control the direction of the truck.
- Throttle Trigger: Pull to accelerate forward, push to brake or reverse.
- Steering Trim: Adjust if the truck pulls to one side when the steering wheel is centered.
- Throttle Trim: Adjust if the truck moves forward or backward when the throttle trigger is centered.
