Installation Guide

1. Choose the installation method suitable for your motorcycle:

Connect three-end wire ③ or USB power cable ② to the charging base ①.

1) Three-end wire ③ installation:

a. Connect ACC signal wire ④ to the motorcycle ACC power supply, connect VCC power wire ⑤ to VCC power supply of the motorcycle, connect GND ground wire ⑥ to the motorcycle ground wire. In this way, the camera can be turned on automatically with the motorcycle key.

b. If there is no motorcycle ACC, you can connect the ACC signal line ④ to the motorcycle ignition interface, such as headlights, etc.

c. If there is no motorcycle ACC, you can connect the ACC signal wire ④ and the VCC power wire ⑤ together and connect them both to the positive pole of the motorcycle power supply. The GND ground wire ⑥ is connected to the motorcycle’s ground wire. After completing the wiring, the camera will automatically turn on. After the motorcycle is turned off, please remember to take the camera away to avoid consuming the motorcycle battery and cover the power base with a waterproof and dustproof cover.

2)USB power cable ② installation:
Plug the USB connector of the USB power cable into the USB port of the motorcycle.

2. Use cable ties to secure and store excess wire length. When fixing and removing wires, please keep them away from anklets/movable mechanisms/high-temperature devices, etc.

Before installing the camera, if there is water or dirt on the ACC charging base, please wipe it dry before installing the device. When not in use, please cover it tightly with a waterproof and dustproof cover to prevent foreign matter from remaining.
