Before installing, read the information below:

1. Please notice below data of power supply input to the monitor and camera.
   Monitor: voltage range 10V-35V >= 800mA
   Camera and Transmitter: 10V-36V >=800mA
   Note: If the power is over 36V to the camera, it will cause damage.
   We recommend DC 12V to the monitor and camera.

2. Before installation, you must test the device. Please reference the image below.

   C. Plug cigarette lighter and turn on the red switch. If you see images on the monitor, it means the system works well.

Tips: Test to make sure that your surroundings appear/display on the monitor screen! Once you have confirmed the monitor works, you are ready to install it.
If there is no image after you have installed the unit, check your connections to the power source. PLEASE NOTE: if you reverse the positive wire and negative wire, it will damage the camera so be cautious. If you cannot verify which wire is positive, connect the white wire to “ground” it (attach it to a metal part on vehicle) and then test the positive wire. Grounding it will protect the camera.

   the camera will be damaged.
