- When the vehicle's ignition is turned off, the device enters parking surveillance mode.
- It records events triggered by motion detection or impact detection.
- The sensitivity of motion and impact detection can be adjusted in the settings menu.
5.4 GPS Notification Function
The built-in GPS provides location and speed data, and also enables the GPS notification function to alert you to various driving hazards.
- The device contains a database of over 39,000 GPS data points across 10 types of dangerous areas.
- When approaching a registered point, the device will provide audio and visual warnings.
- GPS data updates are available free of charge. For more information on GPS data and safety driving support, please refer to the Japan Drive Recorder Council website.
6. Maintenance
6.1 MicroSD Card
The CS-81WQH features a proprietary microSD card maintenance-free system. This system optimizes file management to prevent fragmentation and reduce error rates, meaning you do not need to perform periodic formatting of the microSD card.
- Ensure the microSD card is securely inserted before operation.
- If you experience any recording issues, try removing and reinserting the card.
- While periodic formatting is not required, if you wish to clear all data or resolve persistent issues, you can format the card via the device's menu settings.
6.2 General Care
- Keep the device clean by wiping it with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Ensure the camera lens is clean and free from dust or smudges for optimal recording quality.
- Avoid exposing the device to extreme temperatures or direct sunlight for prolonged periods when not in use.
7. Troubleshooting
If you encounter any issues with your CS-81WQH Drive Recorder, please refer to the following common troubleshooting steps:
- Device does not power on: Check the power cable connection to both the device and the vehicle's power outlet. Ensure the vehicle's ignition is on. Test the power outlet with another device if possible.
- Recording issues (e.g., blurry footage, no recording): Ensure the microSD card is properly inserted. Check if the lens is clean. Verify that the card is not full (though the maintenance-free system should manage this, a very old or faulty card might cause issues).
- GPS signal not acquired: Ensure the device has a clear view of the sky. Avoid mounting locations that might block GPS signals (e.g., under metallic tinting). It may take a few minutes to acquire a signal after startup.
- Quick recording button unresponsive: Ensure the device is actively recording. Check if the touch screen is clean and free from obstructions.
- Parking surveillance not working: Verify that the optional constant power supply cable is correctly installed and connected. Check the parking surveillance settings in the device menu.
- Unexpected warnings or alerts: Review the safety driving support settings in the menu. Adjust sensitivity levels if warnings are too frequent or inaccurate.
If the problem persists after attempting these steps, please contact CELLSTAR customer support for further assistance.
