• Alarm settings on ASC0 / ASC1 and different Multiplexer channels (see AT+CMUX):
- On each interface an individual <text> message can be stored, but only one time setting applies. This
means an alarm <time> set on one of the interfaces overwrites the time setting on all remaining inter-
faces. Therefore, the total number of alarm events returned by the read command AT+CALA? will always
be <n>=0, no matter whether different text messages are stored.
- When the scheduled alarm occurs, the ME sends the URC only on the interface where the most recent
alarm setting was made. The alarm time will be reset to "00/01/01,00:00:00" on all interfaces.
Examples

Next, power down the ME:
When the alarm is executed the ME wakes up to Alarm mode and displays a URC. If available, this line is
followed by the individual <text> most recently saved. If no individual message was saved only the first line
appears.
