Main Functions: tracking device 

1. “track” and “monitor” modes switch: The default mode is “track” (Track mode), if you want to monitor the voice around the device please send "monitor+password" to tracker to switch it to monitor mode, then you make call to the SIM number in the tracker you will can monitor the voice around it; you can send "tracker+password" to swtich the device back to track mode.

2. Single Locating :

* If there has any authorized numbers been set up, tracker will reply to all calls with location report. If the authorized numbers been set up, then only authorized numbers will be able to receive location report from the tracker;

* Dialing the tracker device from the authorized numbers, it will hang up the call and respond a message with google map link and real-time latitude and longitude ;

* When lost fix to satellites (no GPS signals), it will track by LBS / CELL-ID. Then the replied SMS will include two positions:
- GPS coordinates of the last known position.
- LAC code.  Open find “manual track”, and put the received code in LAC and Cell-ID fields to location by LBS technology.

3. Auto track continuously: 
  •  Track with limited times upon time interval, for example send SMS command “fix030s005n +password” to the tracker device, it will report the position information with 30s interval 5 times.


  •  Track with unlimited times upon time interval, for example send SMS “fix030s030m***n+password” to the tracker. Tracker will report a real-time location every 30 seconds when ACC is ON, and report location every 30 minutes when ACC is OFF. Note: The interval must not less than 10s.
  • Smart track upon time and distance interval, this function means that the device can be tracked by preset distance and time interval two factors.

4. Turning points update automatically: the tracker will update the position information automatically to web server once the vehicle changing driving direction over pre-set angle value to form a smooth trajectory consistent with the actual road, this function works only in GPRS mode.

5. GPS drift suppression: this function is deactivated as default, send "suppress+password" to tracker, it will reply “suppress drift ok". The GPS data stop updating if vehicle is not driving (ACC is OFF) and latitude and longitude always keep the same, and GPS data updates automatically when vehicle is moving (ACC is ON).
