Set the Backlight Intensity
You can change the Backlight On intensity and the Backlight Idle intensity separately. You can also
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.

2 Select Backlight Intensity > Backlight On Intensity.
3 Select the intensity you want, and select Back.

Set the Backlight Timeout
The backlight automatically turns on with any phone activity. By setting the Backlight Timeout, you can

default, the backlight dims after the phone is idle for 40 seconds.
