Installation
Inserting the SIM Card
Step 1 Prepare a proper SIM card;
Step 2 Insert the SIM.
After the SIM card is inserted, the device powers on using the backup battery. If the device fails to power on due to low battery, you can connect the device to the external power. Note: The SIM card must be inserted correctly, has GPRS services activated, and is not in arrears. If the SIM is identified and requires a PIN, please disable the PIN request.

Analysis of common problems
| Failurephenomenon | Failure analysis | Treatment method |
| Blue light flashes slowly | Determine whether to use the terminal in areas with poor GPS signals, such as near tall buildings orunderground parking lots | Move the vehicle to a location with a good signal Use the terminal |
| Determine whether the front windshield of the vehicle has metal heat insulation film affecting the signal reception | If there is a film, the equipment will be changed to other vehicles to test whether the blue light is always on, such as in other vehicles without film to test no problem, then the vehicle iscaused by the film | |
| Determine whether there is a shield or signal jammer on or around the car | If there is a shield or source of interference, remove the shield or source of interference and try toreinstall | |
| Blue lightflashing fast | Chip failure | Return to factory for repair |
| Yellow light is flashing fast | Determine whether the SIMcard is installed properly | Check whether the SIM card isinstalled in place |
| Determine if there is dirt or poor contact on the metalsurface of the SIM card | Wipe the metal chip surface with a clean cloth or repeatedly insert andremove the card several times | |
| The yellow light flashes slowly. | Determine if the vehicle is in a place with no mobile network, such as anunderground parking lot. | Please drive the vehicle to a place with good network signal and try to reinstall it. |
| Determine whether theserver background is normal | Ask if the server of the backgroundmanagement platform is normal | |
| Determine whether the SIM card status is normal or not | Check whether the status of the SIM card is normal through the SIM cardinquiry platform | |
| Determine whether there is a shield or signal interferer on the car or around | If there is a shield or source of interference, remove the shield or source of interference and try toreinstall |
