5. Operating Instructions
5.1 Powering On/Off
- Automatic Power On/Off: The dash cam will automatically power on and begin recording when your vehicle's engine starts and power is supplied. It will power off automatically shortly after the engine is turned off.
- Manual Power On/Off: Press and hold the Power button (location varies by model, typically on the side or bottom) for a few seconds to manually turn the device on or off.
5.2 Basic Recording
Once powered on, the dash cam will automatically start recording video from all three channels (front, inside, rear). The recording status is usually indicated by a flashing LED light or an icon on the screen.
5.3 Menu Navigation
Use the physical buttons on the dash cam (e.g., Menu, Up, Down, OK) to navigate through settings. Refer to the on-screen prompts for specific functions.
5.4 Formatting the Memory Card
It is recommended to format the memory card regularly (e.g., once a month) to ensure optimal performance and prevent recording errors. This can typically be done through the dash cam's settings menu. Warning: Formatting will erase all data on the memory card. Back up any important files before formatting.
6. Key Features
6.1 3-Channel Recording
This dash cam simultaneously records video from three perspectives: the front road (1080P), the vehicle's interior (480P), and the rear road (480P). This provides comprehensive coverage for various driving scenarios.

6.2 Loop Recording
When the memory card reaches its full capacity, the dash cam will automatically overwrite the oldest unlocked video files with new recordings. This ensures continuous recording without manual intervention. Important video segments can be locked to prevent them from being overwritten.

6.3 G-Sensor (Gravity Sensor)
The built-in G-Sensor detects sudden impacts or collisions. In the event of an accident, it automatically locks the current video segment, preventing it from being overwritten by loop recording. This ensures critical evidence is preserved.

6.4 Parking Monitoring
With parking monitoring enabled, the dash cam can record in time-lapse mode (one frame per second) when the vehicle is parked. This feature helps protect your vehicle by capturing events while it is unattended. This requires a continuous power supply, often through a hardwire kit (sold separately).
6.5 Starlight Night Vision
The dash cam is equipped with enhanced night vision capabilities, allowing it to capture clear video and photos even in low-light conditions. This improves visibility and recording quality during nighttime driving or parking.

6.6 Reverse Parking View
When the vehicle is shifted into reverse gear, the dash cam automatically displays a rear view on its screen, often with guiding lines. This assists the driver in safely parking and maneuvering the vehicle.

7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the dash cam lens and screen. Avoid using abrasive cleaners or solvents.
- Memory Card Care: Regularly format the memory card to maintain optimal performance. Replace the memory card if it shows signs of degradation or error.
- Temperature: Avoid exposing the dash cam to extreme temperatures for extended periods, as this can affect battery life and device performance.
8. Troubleshooting
8.1 Dash Cam Not Powering On
