Enhancements settings
The enhancements settings menu is shown only if the device
is or has been connected to a compatible enhancement.
Select Menu > Settings > Enhancements > Headset or
Charger.
Network
The network menu allows you to customize the roam call
ringing tone, and the way your device chooses a network
in which to operate while you are within or outside of
your primary or home system. Your device is set to search
for the most effective network. If your device cannot find
a preferred network, it selects a network automatically
based on the option you choose in the network menu.
The menu options you see in your device are based on your
service provider's network. The network determines which
options actually appear in the device menu. For more
information, check with your service provider.
