Operating Instructions
Basic Operation
The dash cam automatically powers on and begins recording when connected to your vehicle's power supply. The screen will display the live view from the camera. Control buttons are located on the bottom of the device for navigation and settings adjustments.
- Power Button: Press to turn the device on/off. Long press to access playback mode.
- Menu (M) Button: Press to enter the system settings menu.
- Arrow Buttons: Use to navigate through menu options.
- OK Button (often integrated with Power/Menu): Confirm selections in the menu.
Key Features
- Loop Recording: The dash cam continuously records video in segments (e.g., 1, 2, or 3 minutes). When the memory card is full, it automatically overwrites the oldest unlocked files to ensure continuous recording. The included 32GB card can be expanded up to 256GB.
- G-Sensor: This built-in gravity sensor detects sudden movements or impacts (e.g., collisions, sudden braking). When triggered, it automatically locks the current video segment, preventing it from being overwritten by loop recording. This ensures critical footage is preserved as evidence.
- 24H Parking Monitoring: With an optional hardwire kit (not included), the dash cam can monitor your vehicle even when parked. It will automatically begin recording if it detects vibration or impact, providing security surveillance.
- Night Vision: The advanced lens and processor enable clear footage capture even in low-light conditions, ensuring visibility of road signs and license plates during night driving.

Troubleshooting
- Camera not powering on: Ensure the car charger is securely plugged into both the dash cam and the vehicle's cigarette lighter socket. Check if the vehicle's power outlet is active.
- Recording issues (e.g., not recording, corrupted files): Verify that the 32GB memory card is properly inserted. If issues persist, try formatting the card through the camera's settings menu. If the card is old or frequently used, consider replacing it.
- Video quality is poor: Ensure the camera lens is clean and free from smudges or dust. Check the resolution setting in the camera's menu to ensure it's set to 2.5K for optimal quality.
- G-Sensor is too sensitive/not sensitive enough: Adjust the G-Sensor sensitivity setting in the camera's menu. A higher sensitivity will lock more files, while a lower sensitivity will reduce false triggers.
- Screen turns off during recording: This is often a power-saving feature. Check the 'Screen Saver' setting in the menu. The camera continues to record even when the screen is off.
