Skin auto iris gate function
When Skin mode is selected, you can also turn on the
skin auto iris gate function by pressing [A.Iris Gate] to

effective area of the skin auto iris on the picture
monitors connected via the PIX1/PIX2 OUTPUT

Skin tone auto iris
If the subject being used as the reference for Auto Iris
is lost during operation, the skin tone auto iris stops
functioning, and the iris value at that time is
maintained. The AUTO buttons of the RCP-series and
MSU-700A/750 then flash. In this condition, not only
is the iris not automatically adjusted but also it cannot
be changed manually. When you wish to change the
iris, turn Auto Iris off.
If Auto Iris is kept ON, the skin tone auto iris will start
functioning when the subject for reference is resumed.
