8.9 AT^SCTM Set critical operating temperature presentation mode or
query temperature
Use this command to monitor the temperature range of the module and the battery. The write com-
mand enables or disables the presentation of URCs to report critical temperature limits.
CAUTION: During the first 15 seconds after start-up, the module operates in an automatic report
mode: URCs can be always displayed regardless of the selected mode <n>.
