To pair the remote with the car, first power on the car, then the remote. The remote will automatically connect. If operating multiple RC cars nearby, pair each car with its remote individually before driving to avoid interference.

The V8 4-channel remote control features a power LED, power switch, throttle adjustment, steering adjustment, steering regulation wheel, and a trigger for forward/backward movement. It also includes a retractable phone holder for optional camera integration. Requires 4*AAA batteries (not included).
Operating Instructions
Driving the RC Car
Once the car and remote are paired, use the trigger for forward and backward movement. The steering wheel controls left and right turns. Adjust the throttle and steering trims on the remote for fine-tuning the car's performance and straight-line tracking. For beginners, it is recommended to practice at lower speeds until comfortable with the controls before attempting maximum speed.
