Setup:
By default the Priority Input Select feature is enabled with the Primary (DVI) and Secondary (SDI) inputs preselected.
If the Priority Input Select feature has been disabled, then a secondary input (pages 7 and 8) must be selected before
the feature may be re-enabled. After selecting the secondary (PIP) input, press and hold the INPUT button for 3
seconds. When the Priority Input Select feature becomes active, a “ Priority Input Select On ” message appears in the
middle of the screen for about 2 seconds, the PIP image is placed behind the primary, the PIP + and - (
◄
and
►
)
buttons are disabled, and the SWAP button remains enabled. When Priority Input Select is enabled, holding the
INPUT button down for 3 seconds disables it.
Operation:
When Priority Input Select is enabled and the primary signal is lost, the secondary input becomes the displayed
image. If the primary signal is restored, its image becomes the displayed image again, and the secondary image is
placed behind the primary image. If both the primary and secondary signals are lost, the monitor alternately scans
the primary and secondary inputs until a signal is detected on one of them. When a signal is detected on the primary
or secondary input, its image is displayed on the monitor.
