Problem
My phone will
not dial
voicemail
commands,
passwords, or
other codes.
My phone's
display is too
dark.
My battery
didn't last as
long as I
expected.
What can I do
to extend
battery life?
Solution
You must send PIN codes and
passwords as DTMF tones while
on a call. You can set your
phone's DTMF tones to be Long,
Short, or Off. If you have trouble
sending numbers, try changing
the DTMF setting.
1 From the home screen, press:
M > Settings > Initial Setup
> DTMF
2 Press S up or down to scroll
to Long or Short .
3 Press SELECT (+) to select it.
Use the Brightness feature to
change the brightness level in
your display (see page 56). You
can also use the Backlight feature to
change the length of time that the
display backlight stays on (see
page 56).
Your battery's performance is
affected by charge time, feature
use, temperature changes,
backlight use, and other factors.
For tips on extending battery life,
see page 11.
