4. Operating Instructions

Once powered on, the dash cam will automatically begin loop recording. Video files are saved in segments (e.g., 1, 3, or 5 minutes) to the microSD card. When the card is full, the oldest unlocked files will be overwritten.

4.2 G-Sensor (Emergency Recording)
The built-in G-sensor detects sudden impacts or collisions. When triggered, the current video segment will be automatically locked and saved to a protected folder on the microSD card, preventing it from being overwritten by loop recording.

6. Troubleshooting
| Problem | Possible Solution |
|---|---|
| Dash cam does not power on. | Check the car charger connection and ensure the vehicle's 12V outlet is functioning. The internal battery may be depleted; charge it for a few minutes. |
| Recording stops or freezes. | Ensure you are using a Class 10 or higher microSD card. Format the microSD card. The card may be full of locked files; delete unnecessary files or format the card. |
| Video footage is blurry. | Clean the camera lens. Ensure the protective film has been removed from the lens. Check if the windshield is clean. |
| G-sensor is too sensitive/not sensitive enough. | Adjust the G-sensor sensitivity setting in the dash cam's menu. |
| Parking monitor not working. | Ensure the parking monitor feature is enabled in the settings. The dash cam needs a continuous power supply for parking monitoring to function effectively (e.g., hardwire kit, not included). |
