17.4 AT^SCTM Set critical operating temperature presentation mode
or query temperature
Use this command to monitor the temperature range of the module. The write command enables or disables the
presentation of URCs to report critical temperature limits.
CAUTION: During a guard period of two minutes after power-up, the module will not switch off, even if the critical
temperature limit is exceeded. This allows the user to issue emergency calls, or calls to a predefined
<phone
number>
before the module switches off.
During this guard period, the module operates in an automatic report mode: URCs can be always displayed
regardless of the selected mode
<n>. Refer to Section 17.4.1, Deferred shutdown for detail.
