5 . 1 . 3 Specifying Auto Iris Gain
Although this value is factory-set, it can be adjusted as needed.
To adjust the value, use either the auto iris gain adjustment trimmer (refer to the Lens Manual) or display operations.
Regardless of the method of adjustment used, the most recent setting takes precedence.
The same auto iris gain value applies to all users.
