> 5.6 | Alarm

> The ALARM can be set with the AT+CALA command. Please refer to the AT Command Set [1] and Hardware Interface Description [2] for more information. One can set an alarm, switch off the module with AT^SMSO, and have the module restart at the time set with AT+CALA. When the alarm triggers the module restarts in a limited functionality mode, the “airplane mode”. Only a limited number of AT commands are available in this mode, although the JVM is started when autostart is enabled. A Java application must be able to handle this mode and reset the module to reinstate the normal mode. The mode of a module started by an alarm is indicated by the URC “^SYSSTART AIRPLANE MODE”.
> Note: For detailed information which functionality is available in this mode see [1] and [2]. The mode indicating URC is created after issuing the very first AT command on any opened channel.
