7. Troubleshooting
If you encounter issues with your Roinvou Dual Dash Cam, refer to the following common problems and solutions:

| "No Memory Card" error | Ensure the TF card is inserted correctly. Try reinserting the card. If the issue persists, format the card (after backing up data) or try a different compatible TF card. |
| Screen is too bright or whitewashed | Adjust the screen brightness settings in the dash cam's menu. Ensure the protective film is removed from the screen. |
| Dash cam not charging or powering on | Check the car power cord connection to both the dash cam and the vehicle's 12V outlet. Ensure the vehicle's power outlet is functional. The dash cam requires continuous power from the car for operation. |
