■ About your device
The wireless devices described in this
guide are approved for use on the
CDMA 800 and 1900 and AMPS
networks. Contact your service
provider for more information
about networks.
When using the features in this device,
obey all laws and respect privacy and
the legitimate rights of others.
Warning: To use any features
in this device, other than the
alarm clock, the device must
be switched on. Do not switch
the device on when wireless
phone use may cause
interference or danger.
■ Network Services
To use the device you must have
service from a wireless service provider

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 them.
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 on
your device menu. Contact your service
provider for more information.
The following device features 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. If your phone displays
a message that the memory is full
when you try to use a shared memory
feature, delete some of the
information or entries stored in the
shared memory features before
continuing. Some of the features,
such as photos, images, and tones
in gallery; text messages; and
applications may have a certain
amount of memory specially allotted
to them in addition to the memory
shared with other features.
