Note

Important:
•  Please refer to the "Hardware Inferface Description" supplied with your GSM

engine 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.

•  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-
tory setting AT^SCTMC=0 was never changed.

Examples

URCs issued when the operating temperature is out of range:

^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.

^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

Battery temperature back to normal temperature.

^SCTM_B: 0

Engine back to normal temperature
