Operating temperatures
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
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
unit
temperature
may
vary
to
a
great
extent
depending
on
the
operating
mode,
used
frequency
band,
radio
output
power
and
current
supply
voltage.
