Operating Instructions
Powering On/Off
The dash cam will automatically power on and begin recording when your vehicle starts and power is supplied. It will power off automatically when the vehicle is turned off.
Recording Modes
The dash cam supports simultaneous 3-channel recording: front (4K), cabin (1080P), and rear (1080P).

Loop Recording
The dash cam utilizes loop recording. When the 128GB memory card is full, the system will automatically overwrite the oldest files to continue recording. Important footage can be manually locked to prevent overwriting.

Collision Sensor (G-Sensor)
The built-in collision sensor detects sudden impacts or vibrations. In the event of a collision, the current video segment will be automatically locked and saved to a protected folder, preventing it from being overwritten by loop recording.

To manually lock a video segment during recording, press the 'M' button on the dash cam.

24-Hour Parking Mode
For continuous surveillance when your vehicle is parked, the 24-hour parking mode can be activated. This feature requires a separate hardwire kit (ASIN: B0G4LLMKG8) to be purchased and installed, as it provides constant power to the dash cam.

Maintenance
Memory Card Management
The included 128GB microSD card is pre-installed. For optimal performance, it is recommended to format the memory card periodically (e.g., once a month) using the dash cam's settings menu. This helps prevent data corruption and ensures smooth recording.
Always power off the dash cam before inserting or removing the memory card to prevent data loss or damage to the card.
Cleaning the Lenses and Screen
Use the provided lint-free cloth to gently clean the dash cam lenses and screen. Avoid using abrasive cleaners or solvents, as these can damage the surfaces.
