mobile displays
NOT ALLOWED Some features are network

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.
Your phone is not
charging Make sure you plugged the
jack of the charger into the
correct connector (see “Charge
the battery” page 2). If your
battery is completely flat, it
might take several minutes of
pre-charge (up to 5 in some
cases) before the charging icon
is displayed on the screen.
