1. Press the input selection button
of the input you wish to adjust.
2. Press the appropriate image
adjustment button (Color, Tint,
Bright, Cont, or Detail). The
LCD display will show the name
of the adjustment and the
number of the current setting.
3. Rotate the Adjust knob (
) to select a
level from 0 (Min) to 255 (Max). The
switcher will time-out to the default
menu after 8 seconds.
4. Repeat steps 2 and 3 for each image
adjustment to be made for that input.
The LCD display may show “N/A”
(not applicable) in place of a
number if that adjustment doesn’t apply to the input’s video format. For
example, the tint adjustment applies only to NTSC composite video, so N/A
will be displayed if the Tint button is pressed when a PAL composite video
input or an RGB input is selected.
Centering
To adjust centering:
1. Press the input selection button of the input to be adjusted.
2. Rotate the vertical (
) or horizontal ( )
shift knob while watching the display.
The LCD screen will appear as shown at
right during centering adjustment.
The shift knobs have no mechanical
limits to their rotation. The shift
values range from 0 to 255, and the
picture will stop moving on screen
when these limits are reached.
Executive mode (front panel lockout)
To prevent accidental changes to settings, follow the steps shown in the illustration
on the next page to enable the System 7SC’s executive mode. Executive mode locks
all front panel functions except input selection and control commands (display and
room functions) and disables setup menu options. The System 7SC’s front panel
and the IR 701 are both affected by executive mode. When executive mode is
active, all functions and adjustments can still be made through RS-232 control.
For details on RS-232 control, see chapter four.
