4. Operating Instructions
4.1 Powering On/Off
The system will typically power on automatically when the vehicle's ignition is turned on and power is supplied. To manually power off, disconnect the power cable or use the designated power button if available.

4.3 Switching Camera Views
You can switch between camera views using the following methods:
- Wireless Remote Control: Use the provided 2.4G wireless remote to manually select any view in full-screen or split-screen mode. Double-click any button on the remote to quickly access the rear camera display.
- Automatic Switching: The monitor automatically switches to the relevant camera view when you activate a turn signal (left/right camera) or engage reverse gear (rear camera).
4.4 Recording Functions
- Loop Recording: The system continuously records footage. When the MicroSD card is full, the oldest files are automatically overwritten by new recordings, ensuring continuous operation.
- Emergency Recording (G-Sensor): In the event of a sudden impact or collision, the built-in G-sensor detects the event and automatically locks the current video segment, preventing it from being overwritten. These files are saved in a separate event folder.
4.5 GPS Data Display
With the GPS tracker connected, the monitor will display real-time driving data including speed, altitude, and atmospheric pressure. This information is recorded along with the video footage and can be viewed during playback using compatible software.
4.6 Night Vision
The side and rearview cameras are equipped with infrared (IR) LED lights, which activate automatically in low-light conditions to provide clear black-and-white images for enhanced visibility at night.
5. Maintenance
5.1 MicroSD Card Management
- Formatting: Regularly format the MicroSD card (at least once a month) through the monitor's settings menu to ensure optimal performance and prevent data corruption.
- Replacement: If the MicroSD card shows signs of degradation or error, replace it with a new high-quality card (Class 10 or higher, up to 256GB).
5.2 Cleaning
- Cameras: Gently wipe camera lenses with a soft, damp cloth to remove dirt or water spots. Do not use harsh chemicals.
- Monitor: Clean the monitor screen with a soft, lint-free cloth. For stubborn smudges, use a screen-cleaning solution designed for electronics.
5.3 Connection Checks
Periodically check all cable connections to ensure they are secure and free from damage. Loose connections can lead to intermittent operation or loss of footage.
6. Troubleshooting
6.1 System Does Not Power On
- Check the power cable connection to both the monitor and the vehicle's power source.
- Ensure the vehicle's power outlet is functioning.
- Verify the vehicle's battery voltage is within the 12-24V operating range.
6.2 No Recording or Recording Stops
- Ensure a MicroSD card is inserted correctly.
- Format the MicroSD card through the monitor's settings.
- Check if the MicroSD card is full; loop recording should overwrite old files, but a faulty card might prevent this. Replace the card if necessary.
- Ensure the recording function is enabled in the system settings.
6.3 Poor Image Quality
- Clean the camera lenses and monitor screen.
- Ensure camera connections are secure.
- Check for any physical obstructions blocking the camera's view.
- In rural areas or extremely low light, image quality may appear different (e.g., black and white for IR night vision). This is normal operation.
6.4 GPS Signal Issues
- Ensure the GPS module is securely connected.
- Place the GPS module in an area with a clear view of the sky, away from metal obstructions.
- Allow sufficient time for the GPS module to acquire a signal after powering on.
