Troubleshooting 71
You have the
feeling that you
miss some calls
To receive all calls, make sure
that none of the features
"Conditional call forward" or
"unconditional call forward" is
activated (see page 54).
When attempting
to use a feature in
the menu, the
mobile displays
NOT ALLOWED
Some features are network
dependent. They are only
available, therefore, if the
network or your subscription
supports them. Contact your
operator for detailed
information on this subject.
The autonomy of
your phone seems
lower that
indicated in the
user guide
The autonomy is linked to
your settings (e.g. ringer
volume, backlight duration)
and the features you use. To
increase the autonomy, and
whenever possible, you must
deactivate features you do not
use.
Your phone
doesn’t work well
in your car
A car contains many metallic
parts that absorb elector-
magnetic waves which can
affect the phone’s
performances. A car kit is
available to provide you with
an external antenna and
enables you to make and
receive phone calls without
handling the handset.
Check with local authorities if
you are allowed to use the
phone whilst driving.
