4. Setup and Installation
- Prepare the Windshield: Clean the area on your windshield where you intend to mount the dash cam. Ensure it is free of dust and grease.
- Apply Electrostatic Sticker: Place an electrostatic sticker on the cleaned area of the windshield. This helps protect your windshield and makes removal easier.
- Attach Mount: Secure the dash cam mount to the electrostatic sticker using the provided 3M adhesive. Press firmly for at least 30 seconds to ensure a strong bond.
- Insert SD Card: Insert the included 64GB U3 SD card into the designated slot on the dash cam. Ensure it clicks into place.
- Mount the Dash Cam: Slide the dash cam onto the mounted bracket. Adjust the lens angle to ensure it captures the road ahead clearly, covering the desired 160° field of view.
- Connect Power: Connect the Type-C power cable to the dash cam and plug the other end into your vehicle's 12V power outlet (cigarette lighter socket). Route the cable neatly along the windshield and dashboard to avoid obstructing your view or interfering with driving controls.


5. Operating Instructions
5.1 Basic Operation
The dash cam will automatically power on and begin recording when your vehicle's ignition is turned on. It will power off automatically when the ignition is turned off.
5.2 Loop Recording
The dash cam records video in continuous loops. When the SD card is full, the oldest unlocked files will be automatically overwritten by new recordings. The included 64GB SD card provides ample storage before overwriting occurs.

5.3 G-Sensor (Emergency Locking)
The built-in G-Sensor detects sudden impacts or rapid acceleration/deceleration. When triggered, it automatically locks the current video segment to prevent it from being overwritten by loop recording. The G-Sensor sensitivity can typically be adjusted in the device settings (Low, Medium, High).

5.4 Built-in GPS
The integrated GPS module accurately records your vehicle's driving route, speed, and location data. This information can be viewed and analyzed through the dedicated smartphone application or compatible computer software.

5.5 Wi-Fi Connectivity and Dedicated App
The dash cam features built-in Wi-Fi (5GHz for faster transfer) for wireless connection to your smartphone. Download the dedicated app from the Google Play Store or Apple App Store. The app allows you to:
- View live footage from the dash cam.
- Review recorded videos and photos.
- Download recordings directly to your smartphone.
- Adjust dash cam settings.

5.6 24H Parking Monitor
When enabled, the 24-hour parking monitor allows the dash cam to continue recording events even when your vehicle is parked and the ignition is off. This feature requires a separate time-lapse hardwire kit (sold separately) for continuous power supply.
5.7 Night Vision
The dash cam is equipped with enhanced night vision technology to capture clear and detailed video footage in low-light conditions, improving visibility during nighttime driving or in dimly lit environments.

6. Maintenance
- Cleaning the Lens: Use the provided dust-free cloth and alcohol cotton to gently clean the camera lens. Avoid abrasive materials that could scratch the lens.
- SD Card Management: Periodically format the SD card (e.g., once a month) through the dash cam's settings to maintain optimal performance and prevent data corruption. Back up any important files before formatting.
- Firmware Updates: Check the TECXERLLON official website or app for any available firmware updates to ensure your dash cam has the latest features and bug fixes.
- Temperature: Avoid exposing the dash cam to extreme temperatures for extended periods, as this can affect battery life and device performance.
7. Troubleshooting
