HOW TO USE
1. Adjust the iris and focus of the lens so that optimum image
may be obtained.
* Usable lenses
CS-mount lenses, whose length "L" (in the illustration)
from the bearing surface of the mount is 4mm or less if
protruded, should be used.
* Using the zoom lens (adjustment of the back focus)
The camera is set at the standard back focus position when
shipped from factory. Depending on types of zoom lenses,
however, slight readjustment may be necessary.
Adjust the lens back-focus by turning the focusing dial in
either direction as per the illustration, referring to the following instructions.
Place an object at any fixed distance and set the focus ring of the zoom lens accordingly.
Set the zoom lens to full TELE position and obtain the best focus position by turning the
focus ring or the zoom lens.
Set the zoom lens to full WIDE position and obtain the best focus position by turning the
focusing dial located on the side of the camera.
Repeat procedures 2 and 3 until focus remains constant throughout the zooming range.
Note: When weight of the lens is more than 1kg (2.2lbs), the camera should be supported by the
lens rather than relying on camera mounting screw.
Adjust the back-focus only when necessary.

* Using an auto iris lens
When a DC driven type auto iris lens is used, set the AUTO IRIS switch at DC, and connect the
plug of the lens (for iris terminal) to the IRIS terminal on the right side of the camera.
When a video feedback type auto iris lens is used, set the AUTO IRIS switch at VIDEO, and
connect the plug of the lens (for iris terminal) to the IRIS terminal on the right side of the
camera. (Refer to Lens manual for the level adjustment.)
* When a video feedback type auto iris lens (peak/average selectable type) is used at peak
mode, BLC may not function well. In such a case, select the average mode.
2. Before your use of the camera at AES (Automatic Electronic Shutter) mode.
* When using an auto-iris lens, set the AES switch at OFF.
(The AES switch is set at OFF when shipped from factory.)
* The AES mode may increase smears on monitors, which is caused by characteristics of CCD
and is not defect.
Set the AES switch at OFF in case smears appear excessively.
