Press F2 (TYPE), to select "CLEAN." If you select "RGB", then as
when the BKDS-2032 board is not installed (standard chroma keying),

For details of the operation when you select "RGB", see the section
"Basic Operations" (page 5-5).
Press F3 (FRGD/BKGD) to select "FRGD".
Press one of F4 (1) to F7 (4) to select the foreground signal.
In a D1 system, you can select F8 (KEY BUS). In this case, select
"CHR" as the key type for the same keyer as the key bus on which the
foreground is selected. (For example, when the foreground is selected on
the key 1 bus, set the key type for keyer 1 to be "CHR".)
