Touch panel description
Point-and-click operations are performed using the touch panel. The touch
panel is used with the graphical user interface (GUI) to present soft keys
directly on the display. Activate all feature keys and soft keys by touching
the item in the display.
The display uses a cold cathode fluorescent lamp (CCFL) for backlighting.
The display is not visible without the backlight, which turns off
automatically after a period of inactivity. You can configure the timeout
period. There is on-off and brightness controls and adjustable contrast.

Application area
The application area provides feature key and soft key status; date and

and Outbox information.
The four softkeys allow you to have three softkeys configured to
support features and one softkey to select menu options, see “Softkey
functionality” (page 14).
