RGB 201 Rxi Universal Interface • Installation and Operation
When a centering control reaches its minimum or maximum
limit, the LCD displays MIN or MAX on the line below H-SHIFT
or V-SHIFT.
Once the centering controls are no longer active, the centering
settings are saved, and the LCD displays the current scan rates.
If DIP switch 1 (DDSP) on the rear panel is set to On (right) and
a centering control is rotated, the LCD displays N/A DDSP ON,
and the image does not shift on screen.
Troubleshooting
