Because it must be connected to the car power supply, it is different from the general external locator. Therefore, it is not recommended to use an external power supply. 2. Installation location: at the roof light above the front windshield; concealed place in the decorative panel below the front windshield; concealed place around the front instrument panel; in the door partition; under the decorative plate below the rear windshield; (such as The windshield is pasted with a metal heat insulation layer or a heating layer, which will reduce the GPS reception signal and cause the GPS to work abnormally. At this time, pay attention to changing the installation location of the device.) Precautions for use 1. Avoid placing it together with the emission source, such as wireless reversing radar , anti-theft device, and other in-vehicle communication equipment; 2. It can be fixed with a cable tie, or pasted with a wide sponge strong double-sided tape; 3. There are GSM antennas and GPS antennas in the device, and the front side should be ensured during installation ( towards the sky), do not stick to metal objects to block the internal GPS antenna on the sky-facing side to avoid affecting the signal. 4. Avoid low battery of 4g vehicle gps tracker. When installing the 4g vehicle gps tracker, in order to avoid inaccurate positioning, you should also pay attention to the remaining power of the tracker, especially those 4g vehicle gps trackers that do not need to be installed without wiring. If the battery power is too low, it is easy to cause drift, deviation and other results. Therefore, the wireless device should be charged in time to avoid the problem of inaccurate positioning due to insufficient power. Specific installation steps 1.
