Vertical Shift switch (V-Shift)
Sometimes when shooting TV screens or monitors with the
same display frequency as the camera, a horizontal black bar
is seen in the viewfinder because the camera is blanking while
the TV is not.
The V-Shift switch shifts the camera blanking. It is spring-
loaded with a central rest position. Holding the switch in the
+ or - position moves the bar up or down so that it is no longer
visible in the viewfinder. This function is only available when
the camera is used in the stand-alone mode and is not active
when the camera is genlocked or on-air.
