5 Electrical Reliability and Radio Characteristics
5.1 Absolute Maximum Ratings
The absolute maximum ratings stated in Table 17 are stress ratings under any conditions.
Stresses beyond any of these limits will cause permanent damage to BGS12.

5.2 Operating Temperatures
Please note that the module’s lifetime, i.e., the MTTF (mean time to failure) may be reduced, if
operated outside the restricted temperature range. A special URC reports whether the module
enters or leaves the restricted temperature range (see [1]; AT^SCTM).
