Before using your phone, fully charge the battery.
The following functions drain the battery more
quickly, and adversely affect talk and standby times:
• Backlighting is frequently on. (To adjust
backlighting, see page 26.)
• The phone is frequently used in analog mode. If
is not visible on the home screen, the
phone is in analog mode. (To set your phone to
operate in different modes, see “Roam Option”
on page 30).
• You are far away from a base station or cell site
when in digital mode.
• Data cables or accessories, such as the Hands-
free headset, are connected to the phone.
• No service is available, or service is available
intermittently. The phone requires more power
to acquire service than to maintain consistent
service.
• The earpiece and ringer volume settings are
high. To adjust the earpiece volume, see “To
adjust the volume manually” on page 6. To
adjust the ringer volume, select
pÉííáåÖë →
pçìåÇë → oáåÖÉê=sçäìãÉ, 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 promptly after receiving them.
