Description
Use F1 to select Luminance menu and F3 to select
Chrominance menu
F1 allows ADJ shaft encoder to set luminance gain
F3 allows ADJ shaft encoder to set black level
CAL sets gain and black level to unity values
F1 allows ADJ shaft encoder to set overall chroma gain
F3 allows ADJ shaft encoder to set U chroma gain
F4 allows ADJ shaft encoder to set V chroma gain
CAL sets all chroma gains to unity values
Note:
The displayed number varies as the shaft encoder is rotated to give an indication of the
setting relative to the factory default
Setting luminance gain and black level
Select the LUMA menu to allow the luminance gain and offset (black level) for the
current mode to be adjusted.
Press the F1 button to allow the shaft encoder to adjust the luminance gain. The shaft
encoder LED will illuminate and an asterisk will appear on the display next to ‘Y GAIN’.
Use the shaft encoder to adjust the luminance gain from 0 to 200%.
Press the F3 button to allow the shaft encoder to adjust the black level. The shaft encoder
LED will illuminate and an asterisk will appear on the display next to 'Y OFFSET'. Use
the shaft encoder to adjust the black level from –30 to +385mV.
Press the CAL button at any time while in this menu to set gain and offset to their default
values (100% and 0mV).
