Operating
1. Powering On/Off
Press the activation button on the 12V cigarette lighter adapter to power the monitor on or off. The camera will automatically activate when the vehicle is in reverse or when the monitor is manually turned on.
2. Basic Functions
Use the menu buttons (Mode, Up, Down) on the side of the monitor to access and adjust settings:
- Brightness/Contrast: Adjust the display's visual quality.
- Image Flip/Mirror: Change the image orientation (M/U Control).
- Reversing Time: Set how long the monitor stays active after disengaging reverse (60s, 90s, 120s).
- Guide Lines: Toggle parking guide lines on or off.
- Reset: Restore factory default settings.
3. Split Screen Mode (with optional second camera)
This system supports up to two cameras. If a second wireless camera (model YW-0629, sold separately) is installed, the monitor can display feeds from both cameras simultaneously in a split-screen view.

4. Driving Mode
The camera can function as a continuous monitoring camera while driving forward, providing a constant rear view. This feature is useful for observing trailers or blind spots, offering more flexibility than traditional backup cameras that only activate in reverse.
Maintenance
1. Cleaning
Regularly clean the camera lens and monitor screen using a soft, damp cloth. Avoid using abrasive cleaners or harsh chemicals that could damage the surfaces.
2. Battery Care
Ensure the camera's solar panel is exposed to sufficient sunlight to maintain its charge. If the vehicle is stored in a garage or shaded area for extended periods, manually charge the camera via the micro-USB port to prevent battery depletion.
Troubleshooting
- No Signal: Ensure both the camera and monitor are powered on and within effective transmission range. Check for any physical obstructions that might interfere with the wireless signal.
- Poor Image Quality: Clean the camera lens thoroughly. Adjust the brightness and contrast settings on the monitor. Verify that the camera's solar panel is clean and receiving adequate light.
- Monitor Not Powering On: Check the 12V power connection to ensure it is securely plugged into the vehicle's accessory outlet. Press the activation button on the cigarette lighter adapter.
- Battery Drains Quickly: Confirm that the solar panel is regularly exposed to sunlight. If the vehicle is frequently parked in shaded areas, manually charge the camera via the USB port.
