Setup Guide
Follow these steps for proper installation and initial setup of your dash cam:
- Format the Micro SD Card: Before first use, insert the provided 32GB Micro SD card into the dash cam. Navigate to the settings menu on the device and select the 'Format' option to prepare the card for recording. This ensures optimal performance and prevents data corruption.
- Clean the Windshield: Use a clean cloth to wipe the area on your windshield where the dash cam will be mounted. Ensure it is free of dust and grease for a secure attachment.
- Attach Suction Cup to Windshield: Securely attach the suction cup mount to the cleaned area of your windshield. Ensure it is positioned to provide an unobstructed view for the camera and does not block your driving visibility.
- Route and Hide Cables: Connect the power cable to the dash cam. Carefully route the cable along the edge of the windshield and down the A-pillar to the cigarette lighter socket. Use the provided crowbar and cable clamps to tuck the cable neatly and securely, preventing interference with driving.
- Install the Rear Camera (Optional): If using the rear camera, connect its cable to the main dash cam unit. Route the cable along the vehicle's interior trim to the rear windshield. Secure the rear camera to the rear windshield using its adhesive mount.
- Plug in the Cigarette Lighter Adapter: Insert the cigarette lighter adapter into your vehicle's 12V power socket. The dash cam will automatically power on and begin recording when the vehicle's ignition is turned on.

Operating Instructions
Understand the various functions and modes of your Abask Dash Cam Q40S.
Basic Operation
- Automatic Recording: The dash cam automatically starts recording when the vehicle's ignition is turned on and stops when the ignition is turned off.

Key Features
- Loop Recording: The dash cam records video in continuous loops. When the memory card is full, the oldest unlocked files are overwritten.
- G-Sensor (Emergency Accident Lock): In the event of a sudden impact or collision, the built-in G-Sensor automatically detects the event and locks the current video file, preventing it from being overwritten.
- Parking Monitor: When enabled, the dash cam will automatically start recording if it detects a collision or vibration while the vehicle is parked. This feature requires a continuous power supply (e.g., hardwire kit, not included).
- Motion Detection: When enabled, the dash cam will start recording when motion is detected in front of the camera. This is useful for monitoring your vehicle when parked.
- Wide Dynamic Range (WDR): WDR technology balances exposure, providing clearer video footage in various lighting conditions, including low light and strong backlight.
- Night Vision: Enhanced night vision capabilities ensure clear recordings even in low-light environments.
- Reverse Assist: When the rear camera is connected and the vehicle is in reverse, the display will automatically show the rear view with parking guidelines.

Proper maintenance ensures the longevity and optimal performance of your dash cam:
- Micro SD Card: Format the Micro SD card at least once a month to maintain optimal performance and prevent data corruption. Use a high-speed (Class 10 or higher) Micro SD card from a reputable brand.
- Cleaning: Use a soft, dry cloth to clean the camera lens and screen. Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the device.
- Temperature: Avoid leaving the dash cam in direct sunlight for extended periods, especially in hot weather, as this can affect battery life and device performance. Store the device in a cool, dry place when not in use.
Troubleshooting
If you encounter any issues with your Abask Dash Cam Q40S, refer to the table below for common problems and their solutions:
| Problem | Solution |
|---|---|
| Dash cam does not turn on. | Ensure the power cable is securely connected to the dash cam and the cigarette lighter socket. Check if the vehicle's 12V power socket is functioning. Test with another 12V device if possible. |
| Recording stops automatically. | The Micro SD card may be full or corrupted. Format the card regularly. Ensure you are using a Class 10 or higher Micro SD card (max 32GB). Replace the card if issues persist. |
| Video footage is blurry or unclear. | Clean the camera lens with a soft cloth. Ensure the protective film has been removed from the lens. Check if the dash cam is securely mounted and not vibrating excessively. |
| G-Sensor is too sensitive/not sensitive enough. | Adjust the G-Sensor sensitivity setting in the device menu. Lower sensitivity for fewer accidental locks, higher for more responsive detection. |
