■ About your device
The Nokia 6255 wireless phone
described in this guide is approved
for use on the CDMA 800, 1900 and
AMPS networks.
Contact your service provider for
more information about networks.
When using the features in this

alarm clock, the phone must
be switched on. Do not
switch the device on when
wireless phone use may
cause interference or danger.
■ Network Services
To use the phone you must have
service from a wireless service
provider. Many of the features in this
device depend on features in the
wireless network to function. These
Network Services may not be
available on all networks or you may
have to make specific arrangements
with your service provider before you
can utilise Network Services. Your
service provider may need to give
you additional instructions for their
use and explain what charges will
apply. Some networks may have
limitations that affect how you can
use network services. For instance,
some networks may not support all
language-dependent characters and
services.
Your service provider may have
requested that certain features be
disabled or not activated in your
device. If so, they will not appear in
your device menu. Contact your
service provider for more
information.
The following features in this device
may share memory: contacts, text
messages, photos, images, and tones
in gallery, calendar notes, games,
and applications. Use of one or more
of these features may reduce the
memory available for the remaining
features sharing memory. Your
phone may display a message that
the memory is full when you try to
use a shared memory feature. In this
case, delete some of the information
or entries stored in the shared
memory features before continuing.
Some of the features, such as
photos, images, tones in gallery, text
messages, and applications may
have a certain memory specially
allotted to them in addition to the
memory shared with other features.
