LCD Backlight
You can select whether or not the phone uses the
backlight or how long the backlight is on. A marginal
increase in standby/talk time can be achieved by
turning the backlight off or setting the saving
backlight.
The following options are available.
Backlight Time: allows you to set the length of
time the phone waits until the backlight turns off
after you press a last key or open the cover, from 8
Seconds On and 20 Seconds On. If you select
Always On, the backlight is on as long as the phone
is on.
Backlight Set: allows you to set the backlight type.
Normal Lighting flashes the backlight when you
press any key. Select Saving Lighting to use the
backlight only between 5:00 PM and 8:00 AM. Doing
this saves the power of the battery.
LCD Contrast
This option allows you to adjust the contrast of the
display to make it darker or lighter.
Select the desired one from Main LCD and
External LCD and adjust the brightness by pressing
the navigation keys. You can also use the volume
keys on the left side of the phone.

System Selection

The system selection feature of your phone enables
you to choose how your phone will roam. Roaming is
a feature which is only relevant in areas where there
are usually at least two cellular service providers
which are referred to as "A" and "B" and have valid
roaming agreements. Your service provider will
provide you with information about this service or
the best roaming methods for you.
The following options are available:
Home Only: With this setting, you cannot roam. If
your home system is not available then your call will
not be connected and the No Service indicator
displayed. In some service areas, an operator may
come on line asking you how you would like to pay
for the call.
Int.Auto Roaming: The phone will search for your
service system first. When the service is not
available, it will search for an alternate system
automatically.
Auto Roaming(A): With this setting, your phone will
always try your call using the Preferred Roaming List
loaded into your phone first, but if your phone cannot
find any preferred systems, then it will attempt to
acquire any digital or analog "A" system.
Auto Roaming (B): With this setting, your phone
will always try your call using the Preferred Roaming
List loaded into your phone first, but if your phone
cannot find any preferred systems, then it will
attempt to acquire any digital or analog "B" system.
