3.4.4 Monitoring Power Supply by AT Command
To monitor the supply voltage you can also use the AT^SBV command which returns the value
related to the reference points BATT+ and GND.
The module continuously measures the voltage at intervals depending on the operating mode
of the RF interface. The duration of measuring ranges from 0.5 seconds in TALK/DATA mode
to 50 seconds when TX62/TX82 is in IDLE mode or Limited Service (deregistered). The dis-
played voltage (in mV) is averaged over the last measuring period before the AT^SBV com-
mand was executed.
If the measured voltage drops below or rises above the voltage shutdown thresholds, the mod-
ule will send an "^SBC" URC and shut down (for details see Section 3.2.5).
3.5 Operating Temperatures
Please note that the module’s lifetime, i.e., the MTTF (mean time to failure) may be reduced, if
operated outside the extended temperature range.
See also Section 3.2.5 for information about the NTC for on-board temperature measurement,
automatic thermal shutdown and alert messages.
Note: Within the specified operating temperature ranges the board temperature may vary to a
great extent depending on operating mode, used frequency band, radio output power and cur-
rent supply voltage.
The below Table 29 lists the ambient temperature ranges the TX62/TX82 is able to operate in.

1. Extended operation allows normal mode speech calls or data transmission for limited time. Within the
extended temperature range (outside the normal operating temperature range) the specified electrical
characteristics may be in- or decreased.
