During vibration alarm time, if the device is located, but fail to connect to the platform, the
device will send longitude and latitude information.
For example,
“Vibration alarm: N23.111748, E114.409215, 11
While if the GPS is neither located nor connect to the platform, the device can not get the
position information. Then it will send SMS
“vibration alarm! Attention” to SOS numbers.
Note
：
1. The device will only alarm once in 5mins.
2. If device can not send SMS normally, please check whether there is enough balance in
the SIM card.
6.5 SOS alarm
Press SOS button for more than 3s to activate GPS automatically. The device will vibrate
twice and then send a location message to the preset SOS numbers.
If the device is located, it will send an accurate GPS location SMS
“Emergency call: Date
time
：
”12-10-31 20:08:18 http://maps.\google.com/maps?q=N22.577169,E113.916790.”
Otherwise, the device will send a LBS location SMS
“Emergency call: Date time
：
”12-10-31
20:08:18 http://maps.\
google.com/maps?q=N22.577169,E113.916754.”
After the message, the device will dial the preset SOS numbers in turn. If any SOS number
answers the call or no response from all the number which been dialed for three cycles, it
will stop dialing. After dialing the SOS numbers, if GPS is located, the device will send GPS
location SMS again.
After activating SOS alarm, if the GPS is not located and fail to connect to the platform
either, the device can not get the position information, and it will send SMS
“Emergency call,
Attention” to the preset SOS numbers.
Note: SOS numbers should be preset for this function!
