Nextel i920 用户手册

A backlight lights the display and keypad when you make or receive a call, open or close 
the flip, or press keys or buttons.

If you do not do any of these things for 10 seconds, the backlight of the internal display 
dims. If you do not do any of these things for 30 seconds or more, the backlight turns off.

While on an active call with the flip open or closed, the internal display or external display 
will remain dimly lit for the duration of the call.

When the backlight is off, pressing a key on the keypad turns the backlight on but does 
not perform the action associated with the key.

On the Home screen, select Start.

Select Settings and then Power Management.

In Backlight timeout, select the amount of time for the Smartphone before the 
backlight turns off, if you do not make or receive a call, open or close the flip, or press 
keys or buttons. 

Select Done.
