The device will automatically switch to base station positioning if satellite signal is weak. To use satellite positioning, please ensure the signal is good and there is no metal material above the device.

• Use SOS to send “000” to disarm.
• Use SOS call number to dial SIM card number and hang up within 10 seconds, then you will get a message saying the device disarm automatically. 

• SIM card should have caller ID service.
• The device is monitoring only if the SOS number is already set.

To set SOS number, you can send “SOS, A, phone number#” to device and then reply “OK”. 

We will offer communication procedures and protocols documentation of the device, which will help the server talk to the device. Any further assistance on the integration, please contact Jimi staff.

GPS signal can be affected by various factors:

• Bad weathers like rain/snow/thunder storm, extreme temperature
• The surrounding buildings or hills/mountains, bad installation method and position, etc.

If the device is under those conditions, the position would be less accurate. If the device location keeps drifting all the time, please contact Jimi staff for support.

To get the device connected, you will need a SIM card with SMS feature and Internet access. Insert the SIM card and power ON the device, then normally the device will self-adapt the correct APN setting of the SIM card, and connect to the Internet. 

• The device is configured to connect the Tracksolid/Car-Matrix server by default.
• If unfortunately, the APN setting cannot be adapted, you can also manually set them by SMS command. For Trackers, useAPN, apnname, user, password# command.
• See the user manual document for more detail.
