Please note that the modem’s lifetime, i.e., the MTTF (mean time to failure) may be reduced if
operated outside the extended temperature range.

1.
Extended operation allows normal mode speech calls or data transmissions for a limited time
until automatic thermal shutdown takes effect. Within the extended temperature range
(outside the operating temperature range) the specified electrical characteristics may be
increased or decreased.
2.
Due to temperature measurement uncertainty, a tolerance of ±5ºC on the stated shutdown
thresholds may occur.
Note that within the specified operating temperature ranges the modem temperature may vary to a
great extent depending on the operating mode, frequency band used, radio output power and
current supply voltage.

Extended operation allows normal mode speech calls or data transmissions for a limited time
until the automatic thermal shutdown mode takes effect. Within the extended temperature
range (outside the operating temperature range) the specified electrical characteristics may
be increased or decreased.
2.
Due to uncertainty in temperature measurement, a tolerance of ±3ºC on the stated
shutdown thresholds may occur.
Note that within the specified operating temperature ranges the modem temperature may vary to a
great extent depending on the operating mode, frequency band used, radio output power and
current supply voltage.
