Setup Instructions
Follow these steps to properly install your MASO Dash Cam in your vehicle:
- Prepare the MicroSD Card: Insert a compatible MicroSD card (up to 32GB, Class 10 or higher recommended) into the dash cam's card slot. Ensure the card is formatted before first use (refer to the "Operating Instructions" section for formatting).
- Attach Suction Mount: Securely attach the suction mount to the dash cam.
- Mount the Dash Cam: Adhere the dash cam with the suction mount to the front windshield, ideally behind the rearview mirror, ensuring it does not obstruct your view.
- Route the Power Cable: Carefully route the USB power cable along the front upper edge of the windshield and down the A-pillar.
- Connect to Power: Insert the cigarette lighter adapter into your vehicle's 12V power outlet and connect the USB cable to the adapter and the dash cam.
- Adjust Camera Angle: Power on the vehicle and adjust the camera lens to capture the desired view of the road ahead.

Operating Instructions
Power On/Off
- The dash cam will automatically power on and begin recording when your vehicle's ignition is turned on (if connected to a switched power source).
- It will automatically power off shortly after the ignition is turned off.
- To manually power on/off, press and hold the power button.
Recording Modes
- Loop Recording: The dash cam continuously records video in segments (e.g., 1, 3, or 5 minutes). When the memory card is full, it automatically overwrites the oldest unlocked footage.
- G-Sensor (Emergency Recording): In the event of a sudden impact or collision, the built-in G-Sensor will detect the event and automatically lock the current video segment, preventing it from being overwritten by loop recording. This footage is saved in a separate "Event" folder.
- Motion Detection: When enabled, the dash cam will automatically start recording if it detects motion in front of the vehicle while parked. This feature requires a continuous power supply (e.g., hardwiring kit, not included) to function when the vehicle is off.
- Night Vision: The dash cam is equipped with night vision technology to enhance video clarity in low-light conditions.

Menu Navigation
Use the buttons on the dash cam to navigate through the menu options. Common settings include:
- Resolution: Set video recording quality (e.g., 1080P, 720P).
- Loop Recording: Adjust segment length (e.g., Off, 1 min, 3 min, 5 min).
- G-Sensor Sensitivity: Adjust the sensitivity of the G-Sensor (Low, Medium, High, Off). Higher sensitivity means it will trigger more easily.
- Motion Detection: Enable or disable this feature.
- Date/Time Stamp: Enable or disable the display of date and time on recorded videos.
- Format SD Card: Erase all data on the MicroSD card. This is recommended periodically.
Maintenance
- Clean the Lens: Regularly clean the camera lens with a soft, lint-free cloth to ensure clear video quality. Avoid abrasive materials.
- Format MicroSD Card: It is recommended to format the MicroSD card every 2-4 weeks to maintain optimal recording performance and prevent data corruption. Back up any important files before formatting.
- Check Mount: Periodically check that the suction mount is securely attached to the windshield.
- Temperature: Avoid exposing the dash cam to extreme temperatures for extended periods, as this can affect battery life and device performance.
