Note
Important:
· Please refer to [1] for specifications on critical temperature ranges.
· Please refer to [1] for specifications on critical temperature ranges.
· To avoid damage the module will shut down once the critical temperature is
exceeded. The procedure is equivalent to the power-down initiated with
AT^SMSO.
AT^SMSO.
· URCs indicating the alert level "1" or "-1" are intended to enable the user to
take appropriate precautions, such as protect the module or battery from expo-
sure to extreme conditions, or save or back up data etc. The presentation of "1"
or "-1" URCs depends on the settings selected with the write command:
If <n>=0: Presentation is enabled for 15 s time after the module was switched
on. After 15 s operation, the presentation will be disabled, i.e. no URCs will be
generated.
If <n>= 1: Presentation of "1" or "-1" URCs is always enabled.

· Level "2" or "-2" URCs are followed by immediate shutdown. The presentation
of these URCs is always enabled, i.e. they will be output even though the fac-

· If the temperature limit is exceeded while an emergency call is in progress the
engine continues to measure the temperature and to deliver alert messages,
but deactivates the shutdown functionality. Once the call is terminated full tem-
perature control will be resumed. If the temperature is still out of range MC35
switches off immediately.

Examples
URCs issued when the operating temperature is out of range:
^SCTM_A: 1
^SCTM_A: 1
Caution: Battery close to overtemperature limit.
^SCTM_A: 2
Alert: Battery above overtemperature limit. Engine switches off.
^SCTM_B: 1
Caution: Engine close to overtemperature limit.
^SCTM_B: 2
Alert: Engine is above overtemperature limit and switches off.
^SCTM_A: -1
Caution: Battery close to undertemperature limit.
^SCTM_A: -2
Alert: Battery below undertemperature limit. Engine switches
off.
off.
^SCTM_B: -1
Caution: Engine close to undertemperature limit.
^SCTM_B: -2
Alert: Engine is below undertemperature limit and switches off.
Example
URCs issued when the temperature is back to normal (URC is output once):
^SCTM_A: 0
^SCTM_A: 0
Battery temperature back to normal temperature.
^SCTM_B: 0
Engine back to normal temperature
