6. Cautions

This camera system is an aid only and should not replace the use of mirrors or direct observation when reversing.
Regularly clean the camera lens if it becomes blocked by rain, snow, dust, or dirt to maintain clear visibility.
Ensure all wiring is properly insulated and securely fixed to prevent short circuits or damage.
Do not attempt to disassemble the camera or monitor, as this may void the warranty and cause damage.

7. Troubleshooting & Maintenance

Troubleshooting:

No image on monitor: Check the reverse light connection and all other wiring connections to ensure they are secure and correctly installed.
Blurry or shaking image: Clean the camera lens thoroughly. Verify that the camera is securely mounted and not vibrating.
Monitor does not auto-switch: Check the trigger wire connection to the reverse light. Review your monitor's settings to ensure auto-switching is enabled and configured correctly.

Maintenance:

Clean the camera lens regularly with a soft, damp cloth to remove dirt and debris.
Periodically inspect all cables for any signs of wear, fraying, or damage. Replace damaged cables immediately.
If the camera system will not be used for an extended period, it is advisable to disconnect its power supply.

8. User Tips

For optimal image clarity, especially when using the AHD 1080P mode, ensure your monitor is compatible with AHD signals.
While the camera is designed for durability, regular cleaning of the lens will significantly improve long-term image quality.
If you experience less-than-expected image quality, double-check your monitor's input settings and ensure the camera is correctly configured for AHD 1080P-25 by cutting the green line as instructed.
