Backlight
The display is illuminated by a backlight. When you press any
key, the backlight lights up.
It dims by two levels of illumination, if no key is pressed within a
given period, depending on the LCD Backlight option under the
Light sub menu in the Sound & Light menu.
(see 4.Settings/1.Phone Setup/1.Sound & Light)
To specify the length of time for which the backlight is active, set
the LCD Backlight option.
