Set the audio level to -60 or -20 dB according to the

CLOSE LIMIT

Hunting can occur when using an auto iris lens under unusually bright conditions, where the iris

is nearly closed. This adjustment avoids the hunting phenomenon. When AES is on, the

AES operates when the light is greater than the close limit value.

When the cursor is shifted to Close Limit, the lens iris is automatically set to the close limit

value. When replacing the lens, set the value to F16.

IRIS SPEED

−128⇔ 0 ⇔＋127

Adjust when using a 6 pin type lens (for a 12 pin type,

use adjustment provided with the lens). The auto iris

response speed increases toward the + side. Adjust

to where hunting does not occur.
