GETTING STARTED
SETTING BACKLIGHT OPTIONS
To save power and extend the life of the display, you can set an option that will auto-
matically shut off the display’s backlight. When the endpoint remains inactive for the
specified amount of time, the display automatically goes into “sleep” mode and the
screen goes dark. To “wake” the screen, either lift the handset or touch the screen. An
incoming call or input from an external mouse or keyboard will also “wake” the
screen.
The default backlight timeout is four hours. You can select a different backlight time-
out as explained below.
NOTE: UC Message alerts (see page 117) and status alerts (see page 118) do not
“wake” the screen, however software upgrade prompts (see page 42) do.
To change the default value for the backlight timeout:
1. Press Start - Settings - Control Panel.
2. Double-press Display.
3. Select the Backlight tab.
4. Select the Automatically turn off backlight while on external power option.
5. Select the amount of time you want the endpoint to remain idle before the back-
light turns off. Timeout choices include:
• 1 minute
• 2 minutes
• 5 minutes
• 10 minutes
• 15 minutes
• 30 minutes
• 1 hour
• 4 hours
6. Press OK.
