When front panel lockout is enabled, if a button is pressed, the button flashes red,
but no change occurs. Nothing—not input switching,
projector control, room control, volume adjustment, or any
other knob- or button-executable function—results from
front panel actions when lockout is active. Changes can still
be made via RS-232 or Ethernet control.
