CONTRAST ADJUSTMENT
Select DISPLAY in the menu (can be called up with the “Next Menu” key). Press “Con-
trast“- until the darkest setting has been attained. Using R776 adjust the contrast so that
the display image is still just visible.
DISPLAY CONTRAST SETTING
Keep “C” depressed until the background noise viewed on the screen vertically
disappears. When the contrast setting is increased further this leads to bloom on the dis-
play.

Press F1 and F5 together and write down the actual monitor defaults. Set status for
DEFAULTS to on, then press ENTER. Now press EXIT and APPLY and SAVE.
Switch unit off and on again, now you have the manufacturer default contrast of the
display. With R776, adjust for best contrast when looking straight to the front to the display.
After this is done, check the monitor defaults with the written down defaults and change
them back if necessary.
