Installation Steps
Step 1: Mount the Camera Choose a location: Choose a location close to the reversing lights/running lights so you can easily splice the power and ground connections or where you want to install. Secure the camera using included brackets/screws. Adjust the camera angle.
*Recommend to test system with temporary mounting and wiring before final installation.

1 Begin by marking the desired camera mounting position and pre-drilling holes for the bracket.

Install the Rear Cameras
2 Then install the bracket with supplied screws, keeping them
loose for adjustment.

3 Align the bracket, position the camera for optimal view, then fully tighten all screws to secure.

Step 2: Power the Camera

To properly install the backup camera, first use a voltage meter to identify the positive and negative wires in your vehicle’s light circuit by testing for 12V DC power – the wire showing positive voltage when the reverse gear is engaged is your positive lead.

Once identified, connect the camera’s red wire to this positive light wire (12V) and the black wire to the negative/ground wire, ensuring all connections are secure and properly insulated for reliable operation.

TROUBLESHOOTING
Camera Pairing Issues 1) Ensure the camera is receiving power. 2) Verify all wiring connections are secure and properly attached. Loose or incorrect wiring may
cause image transmission issues. 3) Check that the camera power lead is connected correctly (polarity matters). 4) Measure the voltage at the camera. If it’s below 12V, the transmitter may fail to function
properly. 5) Try manually pairing the system (refer to the pairing instructions). 6) If pairing fails in the same room, contact our support team at: sales@uszeroxclub.com with
video of pairing attempt. Monitor Won’t Turn On (No Button Light)
1) Inspect wiring for pinched/damaged cables/corroded connectors. Test the power supply (should show 12V+ DC output). Check for voltage drops during startup.
2) Test with alternative power sources – either a portable 12V battery or another vehicle’s 12V socket – to eliminate power supply as a potential issue.
3) Use other cigarette lighter adapter. Or use the included red and black DC pigtail power cable to hardwire the monitor, which will help determine whether the issue lies with the cigarette

If possible, move the objects. 4) Avoid installation near high-voltage power lines/heavy machinery/Other 2.4GHz devices (WiFi
routers, Bluetooth devices or Tire pressure monitoring systems). Temporarily disable nearby 2.4GHz devices. 5) Perform manual pairing (refer to user manual). 6) We have the 10ft antenna extension cable, if you need it, please contact our customer service email: sales2@uszeroxclub.com with your Amazon order ID.
