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.
For more information regarding the module’s thermal behavior please refer to [4].

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