PARTS IDENTIFICATION 
INTRODUCTION
This manual contains instructions to make the installation of the camera and monitor easier. The color backup camera system is a supplement to standard rear-view mirror systems, and will provide additional rear-view vision when installed and maintained properly. It is not intended in any way to be a substitute for careful and cautious driving.
GETTING STARTED
TEST THE SYSTEM
We recommend doing a benchmark test before installation to insure that all components are working properly. To ensure the system works properly after installation, all components should be tested and checked before installation.
Firstly, refer to the what’s in the box page to check whether the component is missing. We do not rule out that some components may be damaged in the case of violent loading and unloading during transportation. If so, please contact us in time.
Secondly, connect the power cable(9 pin connector) to the monitor, the positive and negative terminals to 12-32v voltage, then the power indicator will turn blue and all the buttons into blue backlight, indicating the successful test of the display, can work normally.
Finally, connect 4-pin connector(the other end of the power cable)to the backup camera, restart the power supply of the monitor, and the corresponding channel image will appear, If display normally, so the backup camera is working properly. If not please refer to the troubleshooting.
Note: The monitor can only display the image of the camera of the corresponding channel, if your camera is connected to the AV1 channel, please switch the monitor to AV1.
BEFORE BEGINNING INSTALLATION
- As the camera needs to be fixed on the vehicle, it may need to drill a hole on your car, before drilling please measure the size of boreholes and check that no cable or wiring is on the other side of the wall.
- Keep all cables away from hot or moving parts and electrical noisy components.
- Please clamp all wires securely to reduce the possibility of them being damaged while vehicle is in use.
INSTALLATION GUIDE
- SYSTEM CONNECTION DIAGRAM
- RECOMMENDED INSTALLATION LOCATION
Camera: close to rear marker lights, centered on vehicle.
Monitor: dashboard - CABLE CONNECTION
• RED wire to ignition hot (+) 12-32 volts.
• BLACK wire to ground (-) (please use a chassis ground post).
• GREEN trigger wire is for CH2 camera channel.
Connects green trigger wire to backup light wire or backup beeper wire. This connection is needed to activate the monitor when putting the vehicle into reverse.
- POWERED BY CIRCUIT FUSE
Firstly, recommended and connect the RED Wire(ACC+) to the fuse switch.
Secondly, find the car circuit fuse box under your car cab.
Finally, according to the labels on the fuse hardwire to find the corresponding power fuse and connect the corresponding line (voltage must between 12-32V).
Note: If connecting power directly to battery, the camera is always ON and therefore can drain battery. Therefore it is recommended to connect power to an ignition switched accessory power source. - INSTALLATION CAMERA
Firstly, find the best installation position to install backup camera on your vehicle ,e.g. close to rear marker lights, centered on vehicle.
Secondly, remove the camera U-bracket, mark the hole position with a marker pen, then drilling, after the hole is finished, route the terminal wire of the camera through it and install the screw of the backup camera.
Finally, adjust the best angle. - INSTALLATION MONITOR
Firstly, Find the best installation position to install monitor in your vehicle.
Secondly, Remove the screw around then take out the monitor. Put U-bracket to the right place and adjust angle, prepare 2 screws.
Thirdly, Locking the bracket by screws. Put the monitor into bracket and locking it.
Finally, adjust the best angle to allow optimum driver viewing comfort by themself.
