You can modify the Backlight On intensity and the Backlight Idle intensity separately. You can choose a
high, medium, or low intensity, or turn the backlight off entirely.
When you modify the Maximum Intensity, you modify the entire backlight intensity scale. For example, if
you decrease the Maximum Intensity, the low, medium, and high values for the Backlight On intensity and
the Backlight Idle intensity will decrease proportionally.
The Backlight On intensity applies to following events:
 Any key press
 Incoming calls
 Ending a call, holding a call, resuming a call by the other party
 A voice message received
If you don't press any keys on the phone, after 20 seconds of the backlight turning on, the backlight dims
(or changes) to medium in the following cases:
 A call is in progress
 A call is on hold
 There is an incoming call (ringing)
 There is an outgoing call (ringing back)
 Any menu shows on the display
In all other cases, the Backlight Idle intensity applies.
