Changing the Backlight
Your phone’s backlight has two components:
• Backlight Intensity The brightness of the screen during phone activity
and inactivity. Backlight intensity has three settings:
— Backlight On The brightness of the screen when there is phone
activity.
— Backlight Idle The brightness of the screen when there is no phone
activity.
— Maximum Intensity The brightness scale that applies to both
Backlight On and Backlight Idle intensities.
• Backlight Timeout The number of seconds the phone is inactive before
the backlight dims to its Backlight Idle intensity. The backlight timeout
period begins after your last key press or the last phone event, such as an
incoming call.
You can change 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 change the Maximum Intensity, you modify the entire backlight
intensity scale. For example, if you decrease the Maximum Intensity, the low,
medium, and high levels for both Backlight On and Backlight Idle intensities
decrease.
The backlight automatically turns on with any phone activity. By setting the
Backlight Timeout, you can determine how long the phone should be idle
before the backlight dims to its Backlight Idle intensity. By default, after the
phone is idle for 40 seconds, the backlight dims.
