If your application is battery powered note that charging cannot be started while the engine
is in Alarm mode, i.e. charging will not begin even though the charger connects to the
charger input of the external charging circuit and the module’s POWER pin. See also
Chapter 3.7 which summarizes the various options of changing the mode of operation.
If your host application uses the SYNC pin to control a status LED as described in Chapter
3.12.2.2, please note that the LED is off while the GSM engine is in Alarm mode.
