3. Maintenance
3.1 Cleaning
- Monitor: Use a soft, lint-free cloth to gently wipe the screen. For stubborn smudges, slightly dampen the cloth with water or a screen-cleaning solution. Avoid harsh chemicals.
- Cameras: Periodically clean the camera lenses with a soft cloth to ensure clear visibility. The IP68 rating means they can withstand water exposure, but gentle cleaning is recommended.
3.2 Cable and Connection Checks
Regularly inspect all wiring and connections for signs of wear, damage, or loose contacts. Secure any loose cables to prevent interference or disconnection during vehicle operation.
3.3 SD Card Management
The included 64GB SD card is essential for DVR recording. To maintain optimal performance:
- Format Regularly: Format the SD card every few months through the monitor's settings to prevent data corruption and ensure smooth recording.
- Replacement: If the SD card shows signs of degradation or error, replace it with a high-quality Class 10 or U3 microSD card.
