1, the GPS positioning device is broken.

　　The antenna is broken, the GSM module has a problem, or the GPS module sensitivity is reduced and cannot be located, etc. All belong to the GPS device itself, and it is necessary to judge whether it is broken.

　　2, the SIM card in the GPS positioning device is out of money, or the mobile card package changes, and the Internet function is disabled.

　　Consult the operator of the mobile phone card for details, consult whether the mobile phone card is overdue, whether the Internet function is opened, whether the Internet function is effective, and whether the package has been changed. If it is a mobile phone card, be sure to open GPRS.

　　3, the GPS locator is out of power, shut down.

　　This is the case if you dial the mobile number of the locator from your mobile phone if you are prompted to turn it off. Check the locator power lines for problems, power outages. Whether the supply voltage and current are within the voltage and current range specified for the positioning device installation. The three indicators on the body of the locator are not bright at all.

　　4, the car is in the signal blind area, no signal.

　　Call the mobile phone number of the locator through the mobile phone, if the prompt can not be connected, not in the service area, this is the case. As far as possible, park the car in an environment with good signal conditions (in underground garages, tunnels, remote blocks and other areas without mobile phone signals, which will cause the locator to be offline).

　　5, GPS device installation position is improper.

　　The installation position of the locator can not be too closed, do not have a metal product, so that the equipment is not able to accept the GPS signal sent by the satellite, and the installation position in the car is as close as possible.
