If the status of the GPS module remains in ‘Acquiring’ ( ) for over 5 minutes, check the GPS
antenna connectivity. Depending on the strength of the GPS signal, under normal conditions, the
AutoMonitor should be able to acquire position in less than 3 minutes. Once the GPS module has

GPS based tracking system requires a SIM card to connect to the Internet in order to provide
vehicle status updates to the control centre.
The GPS tracker can store a maximum of 10,000 track points in the internal memory. When the
maximum number of track points is reached, the device will overwrite the oldest track points. All
recorded track points can be downloaded to PC using the AutoMonitor Tachograph software.
