the device will read current position information as origin of coordinates 3 minutes later. Whether GPS data is valid,
the device will perform electronic area defence with zzz.z as radius.
While ACC is turned off, if TLT-2F detects that the defence area is stepped beyond, it will send movement
warning message to all prestored numbers in message mode. Information status is STATE: ACC OS (or upload
current position information to the server in GPRS mode) and dial prestored number. (Whether to call is controlled
by 150/151. After restoration, message is sent instead of calling).
When it enters defence area again after stepping beyond defence area, the device will also send message and
call prestored phone (or upload position message in GPRS mode). Information status is ACC RS.
