- Ensure both the vehicle and remote controller are fully charged and powered off.
- Turn on the remote controller.
- Turn on the S100 vehicle.
- Observe the indicator lights on both devices. They should stop flashing and become solid, indicating a successful connection.
- If binding fails, refer to the specific binding instructions in the included manual (if different from these general steps).
7. Operating Instructions
7.1. Basic Driving
- Place the S100 vehicle on a flat, clear surface.
- Ensure the remote controller is powered on and successfully bound to the vehicle.
