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 5mm or less if
protruded, should be used.
*For C-mount lenses or C-mount coupler, use a supplied
5mm ring between the lens and camera.
Adjust the back-focus only when necessary.
Note: Adjustment of the lens back-focus.
The camera is set at the factory for standard back focus position. Some zoom lenses may
require slight adjustment to the back focus. In those cases, follow these instructions.
Adjust the lens back-focus by turning the back focus 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 on the zoom lens.
Set the zoom lens to full WIDE position and obtain the best focus position by turning the
back focus dial located on the side of the camera.

Repeat procedures and until focus remains constant throughout the zooming range.
Note: When the 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.
* Using an auto iris lens
When a DC driven type auto iris lens is used, set the IRIS address (OSD) at DC and connect the
plug of the lens to the IRIS terminal at the side of the camera.
When a video feedback type auto iris lens is used, set the IRIS address (OSD) at VIDEO and
connect the plug from the lens to the IRIS terminal at the side of the camera. (Refer to the lens
manual for the level adjustment.)
* When a video feedback type auto iris lens (peak/average selectable type) is used at peak mode,
the BLC feature of the camera may not function correctly. In such a case, change the mode to
average.
* When using at auto iris lens, set the shutter mode at OFF (OSD).
* The shutter mode at AUTO (OSD) may increase smears on monitors, which is caused by
characteristics of CCD and that is not fault of the camera.
