When it is Anti-theft emergency state, it sends the
emergency report after the user-defined time.
JAM_DET
String
‘0’ ~’4
GPRS or GPRS+GPS Jamming detection function:
0 = Disable.
1 ~ 4 = enabled jamming detection and if detected first,
check assist functions and then triggered by JAM_DET mode
as follows.

– Inactive, O – Activated if jamming is detected.
Immobilizer: You can disable it by command.
Buzzer: It is disabled automatically after being released from
jamming.
Device will send an alert after recovering the GSM network.
It takes about 2 minutes or more for the device to complete a
jamming detection.
Default: 0.
JAM_CHK_DIST
‘0’ ~’60000’
Meter
This is complementary to the detection function of device
described above on the GPRS jamming by utilizing a
distance value as a parameter when jamming is done.
Once jamming on the GPRS network starts being detected,
the device will also check the distance between the current
location of the vehicle and the First geographical Point (
‘Fp’)
where the jamming started being detected.
If the distance is greater than JAM_CHK_DIST for a while,
triggered by JAM_DET mode.
If
‘0’, skip this procedure.
Default: 500 meters.
JAM_CHK_TM
‘0’ ~ ‘43200’
Sec.
It is complementary to the function of GPRS jamming
detection in an area
‘without GPS connectivity’ (‘No GPS’).
After detecting jamming first in such a bad GPS connecting
area, the device begins to count the 2 time-length factors (
A
and B
) to make a sum (
A + B = C
) if the vehicle moves in the
area:
A: time length that needs to complete the
jamming detection
B: time length that the vehicle driver needs to
complete driving in the area.
