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 can be idle before the backlight dims to its Backlight Idle intensity. By
default, after the phone is idle for 40 seconds, the backlight dims.
To change the backlight intensity:
1 From Home view, select 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 press Back. The default
is High.

is Low.
6 From the Backlight Intensity screen, select Maximum Intensity.

intensity the screen can display, and press Back.
To change the backlight timeout:
1 From Home view, select Settings > Basic > Backlight Timeout.

Changing the Background Picture

light gray background that is named Default.
Your system administrator sets up the background images for your phone. If no background images are
set up, only the Default is available. You can also use a picture of your own as the background image.
