5. Operating Instructions
5.1 Powering On/Off
Once connected to the vehicle's power supply via the cigarette lighter, the monitor will typically power on automatically when the vehicle's ignition is turned on. Use the 'POWER' button on the monitor to manually turn it on or off.
5.2 Adjusting Display Settings
Use the buttons on the front of the monitor to navigate the menu and adjust settings:
- V1/V2: If your monitor supports multiple video inputs, this button switches between them.
- MENU: Accesses the display settings menu.
- - / +: Navigates menu options and adjusts values (e.g., brightness, contrast, color).
- IR: (If present) May control infrared features or act as a confirmation button.
You can adjust the brightness, contrast, and color to suit your viewing preferences and ambient light conditions. The screen ratio can also be adjusted between 16:9 and 4:3.

6. Maintenance and Care
To ensure the longevity and optimal performance of your QXNY backup camera system, follow these maintenance guidelines:
- Cleaning the Monitor: Use a soft, dry cloth to wipe the monitor screen. For stubborn smudges, lightly dampen the cloth with water or a screen-safe cleaner. Avoid harsh chemicals.
- Cleaning the Camera Lens: Although the camera is waterproof and dustproof, periodically clean the lens with a soft, damp cloth to remove dirt, mud, or water spots that may obscure the view.
- Cable Inspection: Regularly check all cables and connections for any signs of wear, damage, or loose connections. Ensure they are securely fastened to prevent signal loss or power issues.
- Environmental Protection: While the camera is designed to be weatherproof, extreme temperatures or prolonged exposure to direct sunlight can affect electronic components. Park your vehicle in shaded areas when possible.
7. Troubleshooting
If you encounter issues with your backup camera system, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No image on monitor | No power to monitor; Loose video cable connection; Faulty camera. | Check if the cigarette lighter adapter is fully inserted and receiving power. Ensure the 4-pin video cable is securely connected at both the camera and monitor ends. Test with another camera if available. |
| Flickering or distorted image | Loose video connection; Power fluctuations; Electromagnetic interference. | Secure all cable connections. Ensure stable power supply. Reroute cables away from other electrical wiring if interference is suspected. |
| Poor night vision | Dirty camera lens; Obstructed LEDs; Insufficient ambient light. | Clean the camera lens. Ensure the camera's LEDs are not blocked. The night vision range is approximately 15M. |
| Monitor buttons unresponsive | Temporary software glitch; Physical damage. | Try powering off and on the monitor. If the issue persists, contact support. |
8. User Tips
- Verify Power Source: Before installation, confirm your vehicle's power system (12V or 24V) is compatible with the camera (9V-36V) and monitor (12V-24V).
- Cable Management: Route cables carefully to avoid pinching, abrasion, or interference with vehicle components. Use cable ties to secure them.
- Optimal Camera Placement: Experiment with camera placement before final mounting to find the best angle for your specific vehicle and needs.
- Replacement Parts: If you need to replace a component, such as the camera, ensure it is compatible with the existing monitor's specifications (e.g., CVBS signal, 4-pin connector, voltage range).
