To counter problems with very bright
highlights
If the subject is too bright, the iris may close too
much, leaving the overall image dark, a condition

the clip highlight function on will clip the signal
above a certain level, reducing the effects of the
auto iris.
Set Operation >Auto Iris >Clip High Light in the
setup menu to On.
