Selecting mounting position Mount the dash cam on either of the recommended positions of the front windshield as appropriate: ① . Near the center of rearview mirror; ② . On the front of the passenger seat. Note: Make sure the camera is below the level line of the rearview mirror. 3. Installing the memory card Open the cover of the memory card slot. Insert the memory card into the slot, with its contacts side facing away from the display screen. And then close the cover. 2. Installing the electrostatic sticker Paste the electrostatic sticker on the selected position, with the gap image facing upwards. Press the sticker to remove air bubbles out. Avoid the edge of the windshield and select the flat and smooth area for the installation. Note: Keep windshield clean and dry without liquid residue to prevent the sticker from losing adhesion and dash cam from dropping. 03 4. Installing the dash cam Paste the dash cam on the electrostatic sticker. Make sure the gap on the adhesive sticker aligns with that on the electrostatic sticker, and the display screen faces the vehicle interior. 5. Connecting the power cord Connect the dash cam and car charger with the power cord. 6. Routing cable Route the power cord to the vehicle’s power outlet and plug the car charger into the power outlet. Start the car engine, and the dash cam will automatically turn on. Notes: • Use the included wiring trim tool to hide the power cord underneath the vehicle’s headliner and rubber seal along the A-pillar. • Depending on the vehicle, the power outlet may be located in a different position. The provided figure is for reference only. 04 Installing the mount Installing/uninstalling the mount Uninstalling the mount 7. Adjusting the dash cam angle Adjust the dash cam angle based on the preview screen. Mount Microphone Dash cam Hold the dash cam and screw it clockwise , and then the dash cam will separate with the mount. 1. Align the microphone with the icon on the mount, and the dash cam is inserted to the mount. 2. Hold the dash cam and screw counterclockwise until the microphone is aligned with the icon on the mount, and then the dash cam is tightened up with the mount. 05 Connecting with the 70mai app This product needs to be used in conjunction with the 70mai app. Follow the steps below to connect it with the app. 1.

If transmitting antennas of directional gain greater than 6 dBi are used, both the maximum conducted output power and the maximum power spectral density shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi. The maximum e.i.r.p. at any elevation angle above 30 degrees as measured from the horizon must not exceed 125 mW (21 dBm). (a) (1) (ii) For an indoor access point operating in the band 5.15-5.25 GHz, the maximum conducted output power over the frequency band of operation shall not exceed 1 W provided the maximum antenna gain does not exceed 6 dBi. If transmitting antennas of directional gain greater than 6 dBi are used, both the maximum conducted output power and the maximum power spectral density shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi. (a) (1) (iii) For fixed point-to-point access points operating in the band 5.15-5.25 GHz, the maximum conducted output power over the frequency band of operation shall not exceed 1 W. Fixed point-to-point U-NII devices may employ antennas with directional gain up to 23 dBi without any corresponding reduction in the maximum conducted output power or maximum power spectral density. For fixed point-to-point transmitters that employ a directional antenna gain greater than 23 dBi, a 1 dB reduction in maximum conducted output power and maximum power spectral density is required for each 1 dB of antenna gain in excess of 23 dBi. Fixed, point-to-point operations exclude the use of point-to-multipoint systems, omnidirectional applications, and multiple collocated transmitters transmitting the same information. The operator of the U-NII device, or if the equipment is professionally installed, the installer, is responsible for ensuring that systems employing high gain directional antennas are used exclusively for fixed, point-to-point operations. (a) (1) (iv) For mobile and portable client devices in the 5.15-5.25 GHz band, the maximum conducted output power over the frequency band of operation shall not exceed 250 mW provided the maximum antenna gain does not exceed 6 dBi. If transmitting antennas of directional gain greater than 6 dBi are used, both the maximum conducted output power and the maximum power spectral density shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi.  For the 5.25-5.35 GHz and 5.47-5.725 GHz bands (a) (2) the maximum conducted output power over the frequency bands of operation shall not exceed the lesser of 250 mW or 11 dBm + 10 log B, where B is the 26 dB emission bandwidth in megahertz. In addition, the maximum power spectral density shall not exceed 11 dBm in any 1 megahertz band. If transmitting antennas of directional gain greater than 6 dBi are used, both the maximum conducted output power and the maximum power spectral density shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi.  For the band 5.725-5.85 GHz (a) (3)For the band 5.725-5.85 GHz, the maximum conducted output power over the frequency band of operation shall not exceed 1 W. In addition, the maximum power spectral density shall not exceed 30 dBm in any 500-kHz band. If transmitting antennas of directional gain greater than 6 dBi are used, both the maximum conducted output power and the maximum power spectral density shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi. 8.2.3 Test Configuration Test according to clause 6.1 radio frequency test setup 1.
