• Connects to the recorder

• Setting up the voltage: If the voltage of vehicle battery falls lower than the preset voltage value, the power to the recorder will be disconnected automatically.
• Setting up the time: If the time passes the preset time (by checking the time after vehicle ignition is turned off), the power to the recorder will be disconnected automatically.

• Use the electricity tester to locate the fuse from which the power is supplied even when the vehicle is turned off, such as the emergency flashing hazard lights, illumination, interior and door lights etc. Connect the yellow wire (B+) to the fuse.

• Use the electricity tester to locate the fuse from which the power is not supplied when the vehicle is turned off, such as the indicator lights and mirror. Connect the red wire (ACC) to the fuse.

• The black wire (GND) must be connected to the metal part of the vehicle for grounding. If not grounded, this product may not work properly. You can use a screw to attach the black wire to the vehicle (try to find a screw hole on any metal part).
