The Background/DSK Input Setup Menu defines the use of the BG/DSK button — either
as an unscaled background ( BG ) or as an unscaled downstream key ( DSK ).
To access the menu:
•
Press the BG/DSK button in the Layer Functions Section . This action causes
the button to blink, enabling setup and modification.

The figure below illustrates the top “ Mode ” line on the Background/DSK Input Setup
Menu . This line determines whether the BG/DSK button will be used as a background or
as a downstream key, and the choice also determines the subsequent appearance (and
available functions) on the menu.
