Notice In order to ensure the safe use of the device and extend the service life of the equipment, the user should fully consider the following factors during installation:

1) After receiving the product, please check the packages of the device and accessories in time. If you find any parts are missing, please contact the dealer in time. 2) When installing and operating the equipment, comply with the specifications of relevant electronic products and the requirements of vehicles and other connected equipment. 3) The installation and construction shall comply with the specifications, which can refer to the relevant national or local standards. 4) Please check the connected power supply voltage, which should fall within the range of 9-36V. To prevent equipment abnormalities due to voltage mismatch, it is recommended to use an operating voltage of 12V or 24V. 5) The hard disk-type terminal should be installed and secured horizontally, ensuring that the inclination angle does not exceed 45 degrees. This precaution is necessary to avoid compromising the terminal's shock absorption capability and reducing the hard disk's lifespan. 6) To receive best positioning signal, ensure that the receiving surface of the GPS antenna faces upward without any metal objects above it. The antenna's bottom should be kept flat, with an inclination angle not exceeding 30 degrees. It is recommended to position the GPS antenna at the junction of the dashboard and windshield for optimal performance. 7) The MDVR device should operate within the temperature and humidity range specified by the technical indicators. 8) The external wires of the devices should have sufficient intervals and the protection of the jacket flame-retardant tube to ensure that the wires will not cause electric leakage due to wear or aging.

Hard disk, SD card, SIM card To start, use the provided key to unlock and open the front panel cover. Once opened, you will find the interface of the SIM card, hard disk box and SD card, as illustrated in the diagram below. Hard Disk Installation: First, loosen the fixed screws located at both ends of the hard disk rack. Then, carefully pull out the hard disk box from the rack. After installing the hard disk into the box, securely fasten it with screws. Next, place the box back into the hard disk rack. Finally, tighten the fixed screws to ensure the hard disk is securely held in place. SD card and SIM card Installation: Insert the SD card into the SD card slot with the connecting finger upward and the SIM card into the SIM card slot. Then close the hard disk cover and lock the hard disk on. 5.2. Antenna installation Please correctly connect the 4G and GPS antennas. To achieve optimal positioning performance, the receiving surface of the GPS antenna must face upwards with no metallic objects above it. The bottom of the antenna should be flat, and its tilt angle should not exceed 30 degrees. Attempt to place the positioning antenna at the junction of the dashboard and windshield. 5.3 Debug screen connection During the debugging process, the device requires an external display screen to assist in adjusting the camera angle and device's online parameters. The device supports two types of signal output: VGA and CVBS. 5.4. Camera Connection First connect channel 1 to 8 audio and video cameras. DSM / ADAS function: this function has an alarm function for fatigue driving, lane departure and other non-standard driving. When the driver is yawning, closing his eyes, smoking, playing with mobile phones, making phone calls and other non-standard driving, this function will alarm through voice and upload the alarm information. 5.5.ADAS/DMS Installation and debugging 5. 5 . 1 DMS Installation 1) Installation position: A-pillar of the cab 2) Installation Height requirements: 10-15cm below the horizontal line of driver's eyes

(the camera should have a slightly inclined upward angle to look up at the driver's eyes, which is better for fatigue detection). 3) Installation Distance requirements: within the range of 70cm-100cm from the driver's head. 4) Installation method: First drill the base of the gimbal and fix it on the A-pillar, use screws to fix the lens on the gimbal, adjust the angle to the display screen and fix the lens with the inner hexagon (the gimbal can be adjusted up, down, left, and right, and the installation will be more convenient) 5) Installation Angle requirements: adjust the camera angle through the video to make the driver's face up and down in the middle of the entire video. 5.5.2 ADAS Installation 1) Installation position: take the center of the windshield as the axis, move up and down according to different vehicle types, and generally install at the lower point (Note:

do not affect the use of the wiper);

2) Installation method: there is a circle of 3M glue on the camera, which can be directly pasted on the glass after tearing off the protective film;

3) The ADAS camera is installed in the center of the windshield and fixed with 3M glue (if the windshield is very inclined, it is installed in the position a little above the center; If it is a vertical windshield, it should be installed at the position a little below the center;

4) The ADAS camera is an analog camera, which does not support hot swap. You need to connect the cable before powering on the main device. If the main device already powered, then connect it to the ADAS camera, whether it is power supply or data line power supply, then the ADAS camera will not work normally, and the display screen can not see the ADAS image; At this time,you need to restart the main device to return to normal. 5.6. Power connection 1)Connect the power to the device according to the definition of power line interface. Before connecting, please check the connected power supply voltage, which should be in the range of 9-36V, The recommended operating voltage is 12V or 24V to prevent the equipment from abnormal due to voltage mismatch. 2)The red line (positive pole) of the power supply is connected to the positive pole of the vehicle main control power supply. The black (negative) of the power supply should be connected to the negative pole or ground of the vehicle power supply. When grounding, it is necessary to ensure the good conductivity of the ground.The power supply (ignition) shall be connected to the ignition control cable, which has power only when the vehicle is running.Please connect the red line and the orange line together to the positive pole of the power supply when debugging the product with the power adapter. 5.7. Product Installation Place Requirements The device can be embedded into the dashboard of the car through the sleeve, and it can also be fixed. Please pay attention to the following points during installation:

1) Waterproof: You should choose a location that is not suitable for water to ensure that the terminal is dry, and pay attention to keeping away from the air outlet of the air conditioner to prevent condensation from accumulating inside the terminal when the temperature difference changes. 2) Earthquake proof: the terminal cannot be suspended and installed in a position with large long-term vibration. 3) Anti interference: The terminal should be kept away from single equipment such as audio-visual and intercom in the car to prevent conduction and radiation interference. 4) The hard disk type MDVR product needs to be installed horizontally, and the inclination angle cannot be greater than 45 degrees, so as not to affect the shock absorption effect of the device and reduce the service life of the hard disk. 5.8. Product Firmware upgrade 1) First, put the upgrade software into SD card / U disk;

2) Insert SD card / U disk with upgrade file;

3) Enter the system menu "system information" to view the application program and MCU version number;

4) The upgrade version number should be different from the device current version number, and the device will be upgraded automatically if the USB flash disk or SD card is inserted;

5) Do not power off or operate the device during the upgrade. System Main Menu Operation Instructions 6.1.
