Press and hold the switch button of the electric skateboard for 10 seconds. When the light on the switch button starts to flicker, turn on the remote control, and press the Power button and the Reverse button quickly at the same time. At this time, the remote control will vibrate once, indicating that your remote control is connected to the electric motor. The skateboard has established a connection. (This function will be set to OK when the skateboard leaves the factory, and no further operation is required in the future).
