We recommend doing a benchmark test before installation to ensure that all components are working properly.      AHD 1080P Wireless Rear View Camera System QUAD VIEW (4) CAMERA INSTRUCTION MANUAL Please read this manual before using the product. It may be different from how it is described in the manual depending on the software version Wireless camera x 1 7" wireless monitor x 1 Mount Bracket x 1 Monitor sunshade x 1 Antenna x 2 Screw Kit for Camera Installation x 1 Camera Power Cable x 1 Package contents Before drilling, please check that no cable or wiring is on the other side of the wall. Please clamp all wires securely to reduce the possibility of them being damaged while vehicle is in use. Keep all cables away from hot or moving parts and electrical noisy components. We recommend doing a benchmark test before installation to insure that all components are working properly. Step 1: Choose the monitor and camera locations. Step 2: Install all cabels in vehicle, when necessary a 0.8 (20mm) hole should be drilled for passing camera cable through vehicles walls. Install split grommets where applicable. Step 3: Once all cables and wiring have been properly routed, perform a system function test by temporarily connecting the system. If the system seems to not be operating properly see troubleshooting. Camera Installation 1. Attach camera bracket close to rear marker lights, centered on vehicle. 2. Camera: drill a 20mm (0.8in) diameter hole into vehicle body near the camera and bracket. Insert camera cable into vehicle not to kink cable) and fit grommet into hole. Apply sealant around grommet to increase resistance to water penetration. connect camera to the camera extension cable which runs inside the vehicle. Before Beginning Installation Installation Guide Troubleshooting Monitor Displays Blue Screen & Displays No Signal Do a hard reset, unplug all cables and power cables and leave them out for 2 minuteS and then re-connect them. Check to ensure that the connection to the camera is tight. Monitor Will Not Power-Up ( no backlight no power button ) Check fuse Check 12v+ to monitor No Image On Screen Verify camera is connected with antenna Verify camera is connected to cable 110 3. Feed as much cable as possible into vehicle with clamp securely. This reduces the possibility of cable being hooked or snagged. The aviation camera cable uses aircraft grade connectors which means the camera cable can be exposed to all weather conditions. 4. Attach camera to bracket using screws and adjust the angle. 5. Wiring camera connect the POWER (red) to 12V and the GROUND (black). 1. To attach the pedestal mount to the dashboard or to the headliner use self-tapping screws and/or the adhesive pad. 2. Attach monitor to mount, and adjust mounting angle to allow optimum driver viewing comfort. Infrared technology built into camera IRs are activated automatically according to the lighting conditions. Grid lines function can be turned on/off by manually from menu. (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 switchedaccessory power source.)
