10. Troubleshooting
10.1 If GPS can not receive the signals normally, please drive to the open areas for positioning. Generally, it needs 1-2 minutes to receive the first coordinates. If the data can not be received after 2-3 minutes, please check the installation position of the device, making sure it is not being shielded by any metal.
10.2 If GSM can not receive the signals normally, please check whether
SIM card is installed correctly or there is no GSM signal at the current location , such as a basement parking, please drive to a place covered by
GSM signal.
