Backlight
A backlight illuminates the display and the keypad. When you press any
key or open the flip, the backlight turns on. It turns off if no key is pressed
within a given period of time, depending on the Backlight menu option.
After one minute, the display turns off to conserve your battery power. To
specify the length of time the backlight is active, set the Backlight menu
option (Menu 9.1.2). See page 88 for further details.
External Display
Your phone has an external display on the cover. It indicates when you
have an incoming call or a message. It also alerts you at the specified time
when you set an alarm by turning on its backlight and showing
corresponding icon on it.
