Backlights
Backlights illuminate the internal and external displays
and the keypad. When you press any key or open the
phone, the backlights come on. They go off when no
keys are pressed within a period of time set in the
Backlight menu.
Note: During a phone call, the display backlights dim and turn off after one
minute to conserve battery power, regardless of the Backlight setting.
See "Backlight" on page 156 for more information.
