4.5.2 How to Use the B3 Mount Lens
AUTO IRIS Operation
If the iris operation is too slow or, on the contrary, too fast
and causes hunting problems in the AUTO IRIS mode, set
the auto iris sensitivity adjustment trimmer of the lens using
the following procedures:
1. Shoot the gray scale chart with the camera.
2. Remove the rubber cap (with an indication such as "Sens.
IRIS GAIN" on it) of the grip on the front side of the
lens, and identify the auto iris sensitivity adjustment
trimmer.
3. Using a Phillips screwdriver, rotate the auto iris
sensitivity adjustment trimmer fully clockwise as viewed
from the front of the lens to set the sensitivity to
maximum.
4. If hunting occurs, adjust the trimmer by gradually
reducing the sensitivity until the hunting problem is
corrected.
5. Make sure that hunting will not occur even when
changing the gain or covering the lens front with the
hand.
If hunting occurs, reduce the sensitivity until the problem
is corrected. Also, if the iris moves slightly with the
flickering light source such as a fluorescent lamp, reduce
the sensitivity until the iris becomes stable.

check the following points first before concluding that there
is a failure.

Are the switches correctly set?
Is there a blown fuse?
Is the POWER switch set to ON?

Set the OUTPUT SELECT switch located on the right side of
the camera to "BARS" and ensure that a normal color-bar
signal is output.
