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.

(a) Internal Synchronous Control
(b) External Synchronous Control by VBS
The internal sync. mode automatically changes to the external sync. mode when the VBS signal
from an external control unit is supplied to 'EXT. SYNC' of 12P terminal on the back of the
camera.
*Required signal for the external synchronization
VBS (75Ωunbalanced) SYNC 0.3Vp-p ± 0.1Vp-p
BURST 0.3Vp-p ± 0.1Vp-p
Limits of frequency deviation within ± 50ppm against the NTSC standard system.
(Horizontal frequency approx. 15.7335kHz ~ 15.7350kHz)
In case of synchronous use of more than two cameras. Horizontal phase and Sub-carrier (SC)
phase can be adjusted to match the images from respective cameras, if necessary.

3. WHITE BALANCE (WB)
Allows you to make the white balance adjustment automatically or manually, for a color
temperature range 2900K - 8000K. (Factory setting is AUTO.)
(1) AUTO:
Sets the automatic color temperature tracking mode. White balance may not be adjusted if
the lighting conditions are bad.
(2) MANU:
Sets the manual adjustment mode. This mode is effective for imaging with low variations
in color temperature.
(3) PUSH:
Use when you want to adjust the white balance with one-push operation. This allows you
to make more accurate adjustment than the AUTO mode. This mode is effective for
imaging with low variations in color temperature. Pressing the UP button after selecting
PUSH sets the data.
4. AGC (AGC)
When the sensitivity selection switch at the left side of the camera is ON, the following
adjustments are enabled: (Factory setting is ON.)
(1) ON:
Allows you to specify the maximum gain for
AGC.
Choices include 6dB, 12dB, and 18dB.
(Factory setting is 12dB.)
(2) OFF:
Allows you to adjust the camera gain manually.

5. SHUTTER (SHUT)
Select either manual or automatic selection of the electronic shutter. (Factory setting is OFF.)
(1) OFF:
Factory setting (1/60 sec)
(2) AUTO:
Automatically selects the electronic shutter.
(3) HS1:
You can select among the 8 shutter speeds.
Choose one from:
1/100 1/125 1/250 1/500 1/1,000 1/2,000
1/4,000 and 1/10,000 sec.
(4) HS2:
You can specify the shutter speed from 1H to
262H in 1H increments.
(approx. 1/10,000 sec - 1/60 sec)
Choosing the AUTO mode or the high speed shutter
mode under the illumination of a flurescent light
may cause flicker or change in the white balance.
In this case, set SHUT to the OFF mode and use
the auto iris lens.
(5) LS1:
In the slower-side shutter, you can specify the
speed from 2F (field) - 510F (field) in 2F
increments.
NTSC: (2/60 sec - 510/60 sec)
(6) AUTO2:
Automatically changes the slower-side shutter
depending on the quantity of light. You can
also choose the upper-limit speed from 2F, 4F,
8F, 16F, 32F and 64F.
* If you choose 1/100, there will be no flicker
even when the object becomes brighter.
* In case the accumulated time becomes long
in the slower-side shutter mode while
shooting a fast-moving object, the picture
may viewed with after-image.
FREEZE PICTURE MODE
You can enter the freeze picture (field) mode by pressing the DOWN button of the data
button while the SHUTTER mode is OFF.
To return to the original live picture, press the DOWN button again.
