You can change the Backlight On intensity and the Backlight Idle intensity separately, and you can choose a
high, medium, or low intensity, or turn off the backlight 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.
To change the backlight intensity:
1 Navigate to Settings > Basic > Backlight Intensity.
2 From the Backlight Intensity screen, select Backlight On Intensity.
3 From the Backlight On Intensity screen, select the intensity you want, and select Back. The default is
High.
4 From the Backlight Intensity screen, select Backlight Idle Intensity.
5 From the Backlight Idle Intensity screen, select the intensity you want, and select Back. The default is
Low.
6 From the Backlight Intensity screen, select Maximum Intensity.
7 From the Maximum Intensity screen, select Up or Down, or drag your finger along the slider, to
increase or decrease the maximum intensity.
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, the backlight dims after the phone is idle for 40 seconds.
To change the Backlight Timeout:
1 Navigate to Settings > Basic > Backlight Timeout.
2 From the Backlight Timeout screen, select the number of seconds the phone is idle before the
backlight dims. The default is 40 seconds.
By default, your phone is set up with a power-saving mode that turns off the screen to conserve energy. Your
phone enters power-saving mode after it has been idle for a certain period of time. You can configure the
period of time that the phone is idle before the screen turns off. You can configure different idle timeouts for office
hours and off hours, such as evenings and weekends.
