MC75 AT Command Set
18.2 AT+CALA
s
• Alarm settings on ASC0 / ASC1 and different Multiplexer channels (see AT+CMUX):
- On each interface an individual message can be stored, but only one time setting applies. This
means an alarm set on one of the interfaces overwrites the time setting on all remaining interfaces.
Therefore, the total number of alarm events returned by the read command AT+CALA? will always
be =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
EXAMPLE 1
You may want to configure a reminder message for July 31, 2005, at 9.30h, including the message "Good

EXAMPLE 3
To enable the ME to wake up into Airplane mode, e.g. on July 20, 2005, at 8.30h, enter

followed by the individual most recently saved. If no individual message was saved only the first line
appears.
