CHROMA KEY Menu

the keyer concerned.
Accessing the chroma key menu
For example, to access the M/E-1 CHROMA KEY menu, use any of the
following operations:
• Press the CHR KEY top menu button in the M/E-1 group of the menu
control section.
• In the M/E-1 bank, press the cross-point button to which the CRK FILL 1
signal is allocated, twice in rapid succession.
• In the M/E-1 bank, press the CHR key type selection button twice in rapid
succession.
If the BKDS-2031 only is installed, the menu appears as shown below.
