Operating Instructions

The 4.3-inch display screen provides real-time image preview, video playback, and allows for adjustment of settings.

The large display allows for high-definition picture quality and convenient playback of recorded videos at any time.
4. Wire Controller Functions
The wire controller simplifies operations, allowing you to manage the dash cam without frequently looking at the screen.

Shutdown and other functional operations can be performed conveniently through the buttons on the wire controller.

- Accessing GPS Data (Calories, atmospheric pressure, altitude, latitude/longitude, speed, cycling time, total mileage)
- Other functions as per device settings.
5. Infrared Night Vision
The camera is equipped with a 940nm invisible infrared light night vision lens, enabling clear recording of road conditions even in low-light or nighttime environments.

The 940nm invisible infrared light night vision lens ensures clear recording of road conditions when driving at night.
6. GPS Data Display
The external GPS module provides precise positioning and records various riding data. This data can be viewed on the display screen via the wire controller.

The screen displays information such as speed, distance, coordinates (N, E), altitude, and time, providing comprehensive riding data.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the display screen and camera lens. Avoid using abrasive cleaners or solvents.
- Waterproof Care: While the host unit has an IP65 waterproof rating and the camera an IP67 rating, it is important to note:
- Do not soak the device in water for a long time.
- Do not use a high-pressure water gun to wash the device.

The dash camera is waterproof and dustproof for safe and durable use. The device is designed to be waterproof and dustproof, but avoid prolonged submersion or high-pressure washing.
- Memory Card: Periodically format your memory card (after backing up important files) to maintain optimal performance and prevent data corruption.
- Storage: When not in use for extended periods, store the dash cam in a cool, dry place away from direct sunlight.
Troubleshooting
- Device not powering on:

- Verify that a compatible MicroSD/TF card (Class 10 or higher) is properly inserted.
- Format the memory card. If issues persist, try a different memory card.
