4. Setup and Installation
Before permanent installation, it is recommended to test all components to ensure they are working correctly.
4.1 Camera Mounting
The camera can be mounted using either 3M adhesive or screws, depending on your preference and vehicle type. Choose a location that provides a clear view of the rear of your vehicle, typically above the license plate.

4.3 Wiring Diagram and Connection
The system uses an integrated power cord, simplifying the connection process. You have two primary wiring options:
Cigarette Lighter Power (Plug and Play):
Connect the camera to the monitor using the provided 4-pin video power cable. Then, plug the monitor's power adapter into your vehicle's cigarette lighter socket. This method allows for manual switching of the system.Reverse Trigger (Automatic Activation):
For automatic activation when reversing, connect the camera and monitor as described above. Additionally, connect the red wire from the power cable to your vehicle's reverse light positive (+) terminal. The black wire should be connected to ground (-). In this setup, the cigarette lighter plug is typically cut off, and the system will automatically display the rear view when the vehicle is put into reverse.

5. Operating Instructions
5.1 Powering On/Off
If connected via the cigarette lighter, the monitor will power on when the vehicle's ignition is on and the cigarette lighter provides power. If wired to the reverse trigger, the monitor will automatically activate when reverse gear is engaged.
5.2 Menu Navigation
The monitor features an adjustable menu for various settings. Use the buttons on the monitor (typically labeled 'M' for Menu, '<' and '>' for navigation, and 'AV' for AV input selection) to access and adjust settings such as brightness, contrast, color, and parking line options.
5.3 Mirror Control (Rear to Front View)
The camera supports a mirror function, allowing you to switch between a mirrored rear view (default for reversing) and a normal front-facing image. To change this setting, locate the white wire on the camera's cable. Cutting this wire will typically toggle the image between mirror and normal view.

5.4 Parking Line Adjustment
The system provides adjustable parking guide lines to assist with reversing. To enable or disable these lines, or to adjust their appearance, locate the green wire on the camera's cable. Cutting this wire will typically toggle the parking lines on or off.
*Note: Some models may offer further adjustments through the monitor's menu. Refer to the monitor's on-screen display for specific options.*
5.5 Night Vision
The camera features Starlight Night Vision technology, which automatically adjusts gain control, white balance, and backlight compensation to provide clear images in low-light conditions. No manual adjustment is typically required for night vision functionality.

6. Maintenance
- Cleaning the Monitor: Use a soft, dry cloth to clean the monitor screen. For stubborn smudges, a slightly damp cloth with a mild, non-abrasive cleaner suitable for electronics can be used. Avoid spraying cleaner directly onto the screen.
- Cleaning the Camera Lens: Keep the camera lens clean from dirt, dust, and water spots to ensure clear image quality. Use a soft, lint-free cloth, possibly dampened with lens cleaner, to gently wipe the lens.
- Waterproof Camera: The camera has an IP68 waterproof rating, meaning it is protected against dust and can withstand immersion in water up to 1.5 meters for 30 minutes. However, avoid high-pressure washing directly on the camera.
- Cable Inspection: Periodically check all cables for any signs of wear, damage, or loose connections. Ensure cables are securely routed and not pinched.

8. User Tips
- Pre-Installation Test: Always test the monitor and camera system with a temporary power source before routing cables and making permanent installations. This helps identify any faulty components early.
- Cable Management: Route cables carefully to avoid pinching, chafing, or interference with other vehicle components. Use cable ties or clips to secure them.
- Optimal Camera Placement: Experiment with camera placement to find the best viewing angle for your vehicle, ensuring it covers blind spots effectively.
