3. SD Card Insertion
The 64GB SD card is pre-inserted into the dash cam. If you need to replace it, ensure the dash cam is powered off before inserting or removing the SD card. The device supports up to a 128GB card.

Operating Instructions
1. Power On/Off
The dash cam will automatically power on and begin recording when your vehicle starts. It will power off automatically when the vehicle is turned off.
2. 3-Channel Recording
The CHENSIVE A98 records simultaneously from three cameras: front (4K/2160P, 170° wide angle), cabin (1440P, 150° wide angle), and rear (1080P, 160° wide angle). This provides comprehensive coverage of your driving environment.

3. Loop Recording
The dash cam features loop recording, which automatically overwrites the oldest unlocked footage with new recordings when the SD card is full. This ensures continuous recording without manual intervention.

4. G-Sensor (Automatic Incident Detection)
The built-in G-sensor detects sudden shakes or collisions. When an impact is detected, the current video footage is automatically locked and protected from being overwritten, preserving critical evidence.

5. 24H Parking Mode
When the dash cam detects a collision or motion while parked, it will automatically turn on and record a protected video. For 24-hour continuous parking monitoring, a hardwire kit (sold separately) is required to connect the dash cam to your car's fuse box.

6. Super Night Vision & WDR
Equipped with an f/2.0 large aperture, WDR (Wide Dynamic Range) technology, and 4 infrared lights for the cabin camera, the dash cam performs exceptionally well in low-light conditions, ensuring clear and accurate recordings day or night.

7. Parking Assistance
The rear camera provides a clear rear view and parking guidelines when the reverse gear is engaged, aiding in safe parking maneuvers. Note: The red reverse line on the extension cable of the rear camera should be connected to the positive pole of the reverse light for this feature to work.

Maintenance
Care and Cleaning
- Regularly check the mounting to ensure the dash cam is securely attached.
- Clean the camera lenses periodically with a soft, lint-free cloth to ensure clear video quality.
- Do not expose the device to high temperatures for extended periods. If it overheats, disconnect the power and allow it to cool down.
- Format the SD card monthly to maintain optimal performance and prevent data corruption.
Troubleshooting
Common Issues and Solutions
- Dash Cam not powering on: Ensure the power cable is securely connected to both the dash cam and the vehicle's power outlet. Check the vehicle's 12V power outlet for functionality.
- Video footage is unclear: Clean the camera lenses. Ensure the protective film has been removed from the lenses. Check the video resolution settings.
- SD card full: The loop recording function will automatically overwrite the oldest files. Ensure emergency locked videos are manually deleted if no longer needed. Consider upgrading to a larger capacity SD card (up to 128GB supported).
- Parking mode not working: Ensure the G-sensor sensitivity is set appropriately. For 24-hour parking monitoring, a hardwire kit (sold separately) is required.
- Rear camera not displaying: Check all cable connections between the rear camera and the main unit. Ensure the rear camera is properly powered.
