Required Camera Settings

The EVF signal switching is controlled by the KA-R25U return video unit. The normal EVF
output is the GY-HD250U RGB signal. When the RET (return) button located on the lens
control handle is depressed and held down, a converted Black & White image of the return
video signal is shown in the EVF. Once the RET button is released, the KA-R25U switches
the EVF image back to the RGB signal from the camcorder.
Mounted View
The KA-R25U return video
unit mounts conveniently on
the GY-HD250U's handle as
shown (right).
EVF and microphone can be
