2. Pairing the Remote Control
The 2.4GHz remote control system is designed for automatic pairing. Ensure both the vehicle and the remote controller are powered on. The remote control will automatically establish a connection with the vehicle. If pairing fails, turn both devices off and on again. This technology allows multiple vehicles to operate simultaneously without interference.
