See * below
* Note. For Maestro modem user :
This is NOT the input voltage of the external power supply for the mode, it is an internal input voltage inside
modem circuit. Since there is voltage regulation inside, modem user should not change this trigger value
“Periodic” mode:
When user enter AT+TMODE=1 command the modem will perform periodic check every one minute :
- firstly it will check if the modem is registered to the network; if the modem is not registered to the network it will
increase a counter by one. If the counter reach 5 (i.e. not registered for consecutive 5 minutes) the modem will reset
- if the modem is registered to the network the counter will be reset to 0 and perform check same as “one shot” mode
- if the result of the network signal strength is lower than the setting of AT+TMODE=3,x the test result will be sent over
SMS to the telephone number set by AT+TMODE=2,xxxxxxx (max number of digit is 20)
- if the result of the input voltage is lower than the setting of AT+TMODE=4,x the test result will be sent over SMS to
the telephone number set by AT+TMODE=2,xxxxxxx
- if 3 consecutive check fails (i.e. 3 SMS sent) then the periodic mode check will be disabled automatically.
- network signal trigger level range is from 1-31
- input voltage trigger level is from 3500 to 4100
