adjust backlighting, select

select an option such as 10 seconds or

analog mode. If is not visible on
your home screen, you are in analog
mode. (To set your phone to operate
in different modes, see “To select
digital or analog mode” on page 20).
• You are far away from a base station or
cell site when in digital mode.
• Data cables or accessories are
connected to the phone.
• Service is not available or is available
intermittently. The phone requires
more power to acquire service than to
maintain service.
• The earpiece and ringer volume
settings are high. To adjust the
earpiece volume, see “To adjust the
volume” on page 6. To adjust the
ringer volume, select
Menu 3 Settings
3 Sounds 3 Ringer Volume, and press
left to lower the volume.
• Check how often voicemail
notifications, pages, and text
messages are received, and how
quickly they are acknowledged. To
use power most efficiently,
acknowledge notifications and
messages immediately.
