4.3 microSD Card Installation

Insert a compatible microSD card (Class 10/UHS-1 or higher, up to 256GB) into the microSD card slot. The camera will format the card upon first use or when selected in the settings.

Diagram Description (Page 14): Details the process of formatting the microSD card through the dash cam's menu. It also shows the file structure on the card: the main DCIM folder contains subfolders like MOVIE for regular recordings and RO for event recordings.

5. Operation

5.1 Recording Modes

• Normal Recording: The dash cam automatically records when powered on.
• Event Recording: Triggered by the G-Sensor detecting an impact or manually by pressing the REC button. These files are typically protected from overwriting.
• Parking Mode: Records footage when the vehicle is parked and motion or impact is detected. Requires the Hardwire Kit (HK3-C) for continuous power and parking mode activation.
• Time-lapse Recording: Captures frames at set intervals to create a time-compressed video, useful for monitoring long periods.
• Loop Recording: Allows the camera to continuously record by overwriting the oldest footage when the microSD card is full. Options for recording segment length (Off, 1, 2, 3, 5, 10 minutes) are available.
