Turn Freerun Feature On/Off
Freerun involves displaying a Blue Screen at 480i when the currently selected input does
not have a valid signal present. This happens when auto-switch is disabled and the PS190 is
switched to a input with no signal present. When this feature is turned off, the display will show
a signal not present or disconnect. By default, FRUN is enabled.
Command Format
FRUN #
Replace the “*” with a 0 - turn off freerun or 1 to turn on freerun.
