Before using the dash cam, insert a Class 10 or higher Micro SD card (up to 32GB) into the designated slot. Ensure the card is inserted correctly with the contacts facing the camera's screen.

1. Locate the Micro SD card slot on the side of the dash cam.
2. Gently push the Micro SD card into the slot until it clicks into place.
3. To remove, push the card in again until it clicks, then release, and it will spring out.

3.2 Mounting the Dash Cam

The dash cam is designed to be mounted on your car's windshield using the provided suction mount.

1. Clean the area on your windshield where you intend to mount the dash cam.
2. Attach the suction mount to the dash cam.
3. Press the suction cup firmly against the windshield and flip the lever to secure it.
4. Adjust the angle of the dash cam to ensure a clear view of the road ahead. The mount allows for 360-degree rotation.

3.3 Wiring and Power Connection

Connect the dash cam to your car's power supply and install the rear camera.

1. Connect the power cable (car charger) to the dash cam and plug the other end into your car's cigarette lighter socket.
2. Connect the rear camera cable to the main dash cam unit.
3. Route the rear camera cable to the back of your vehicle. For the backup camera function to work, connect the red wire from the rear camera cable to your car's reversing lamp positive terminal. If your car has a built-in reverse system, this red wire connection may not be necessary.
4. Mount the rear camera in a suitable location, typically above the license plate or on the rear window, ensuring a clear view.

4. Operating Instructions

4.1 Power On/Off

The dash cam is designed for automatic operation. It will start recording immediately after your car's ignition is turned on and will save the video and shut down when the engine is turned off.

• Automatic Power On/Off: Connect the dash cam to the car charger. It will power on and begin recording automatically when the car engine starts. It will power off automatically when the engine is turned off.
• Manual Power On/Off: Press and hold the power button on the dash cam to manually turn it on or off.

4.2 Dual Lens Recording

The dash cam simultaneously records footage from both the front and rear cameras, providing comprehensive coverage of your driving environment.

4.3 Loop Recording

Loop recording ensures continuous recording by overwriting the oldest footage when the Micro SD card reaches its storage limit. This eliminates the need for manual deletion of old files.

4.4 G-Sensor (Accident Auto-detection)

The built-in G-Sensor automatically detects sudden collisions or impacts. When triggered, it immediately saves the current footage and locks it to an "SOS file" to prevent it from being overwritten by loop recording. This protects critical video evidence in case of an accident.

4.5 Parking Monitor

When the parking monitor function is enabled, the dash cam will automatically turn on and begin recording if any shake or collision is detected while your vehicle is parked. This provides 24-hour protection for your vehicle.

4.6 Backup Camera Function

When the rear camera is properly connected to the car's reversing lamp, the dash cam display screen will automatically switch to a full-screen view of the rear camera and display parking guidelines when the vehicle is put into reverse gear. This assists with safe parking.

4.7 Night Vision and WDR

The dash cam is equipped with 4 IR LEDs and Wide Dynamic Range (WDR) technology to enhance video clarity in low-light conditions, ensuring clear capture of license plates and road signs even at night.

5. Maintenance

• SD Card Formatting: It is recommended to format the Micro SD card regularly (e.g., once a month) to ensure optimal performance and prevent data corruption. This can usually be done through the dash cam's menu settings.
• Cleaning: Use a soft, dry cloth to clean the camera lenses and the dash cam screen. Avoid using abrasive cleaners or solvents.
• Temperature: Avoid exposing the dash cam to extreme temperatures for prolonged periods.
• Firmware Updates: Check the manufacturer's website periodically for any available firmware updates to improve performance or add new features.
