Chapter 4. Using the CAREU P2
This chapter will guide you to major functions of CAREU P2 and necessary settings to operate the
device.
4.1. Self Geo-fencing
The device user may define the Geo Fence radius through protocol command (AT$SGF,
default 100m), after triggering the Geo-fencing button, CAREU P2 will use its last known
fixed GPS location as the center to create a circular fence. Alert reports will be generated
when the device either exits or re-enters this self defined Geo-fence.
• To enable/disable self define geo-fencing for your CAREU P2:
 Create the Self Geo-fence:
Press and hold Geo-fencing Button for 2 seconds. CAREU P2 will make a short
beep twice first, and then makes a short beep 3 times when valid GPS fix location is
acquired. The GSM / GPS LED will both flash simultaneously every 3 seconds.
Note: If valid GPS fix location is not acquired (Geo-fence cannot be created),
the device will indicate such status by vibrating 3 times.
 Cancel the Self Geo-fence:
Press and hold Geo-fencing Button for two seconds.CAREU P2 will make one long
beep and cancel the Geo-fence creating process.
