Pairing the Remote Control
The car and remote control use 2.4G frequency, allowing multiple cars to race without interference. Typically, the car and remote are pre-paired. If re-pairing is needed:
- Turn on the RC car.
- Turn on the remote controller.
- The remote's indicator light should blink and then become solid, indicating a successful connection. If not, turn both off and repeat the process.
