Digital Color Camera
- Line Lock
To set the camera in LL mode for synchronization with the power supply frequency, take the following steps.
1. Turn switch to “L”;
2. Turn switch to “PHASE”;
3. Press the + or – button and to make the phase variable.
Adjust with the button and so that the vertical phase of the camera matches with the vertical
phase of another camera (or system) with a multi-channel oscilloscope.
For initial setting, press RESET button .
- White Balance
White Balance can be adjusted within the scope of 2900-8000K color temperature.
When switch is at “AUTO” the white balance is adjusted automatically.
For manual adjustment, take the following steps.
1. Turn switch to “MANUAL”;
2. Turn switch to “W,B”;
3. Pressing “R” button increases redness while pressing “B” increases blueness. For initial setting,
press RESET button .
- BLC (Back Light Compensation)
The switch 7 improves an image that is darkened because of backlighting. Set this switch to ON for
backlight subjects.
- AES
Turning this switch 8 “ON” when a lens with a manual iris diaphragm is used enables the automatic
adjustment of image brightness. In this case the shutter speed changes according to the brightness of
the subject.
AES functions only when AGC switch 9 is turned on.
- AGC
The switch 9 automatically increases the camera’s sensitivity when the level of amdient light drops.
ON: AGC is activated.
OFF: AGC is not activated.

Mounting a Lens
Mounting a Lens
1. Before mounting a lens, check whether it is a C-mount or CS-mount lens.
* The F mark indicates a focal point.
2. Mount the lens on the camera by turning the lens clockwise.
Adjust its position.
3. When using an auto-iris lens with an EE amplifier, turn the switch to the “VIDEO” side.
When no EE amplifier is equipped, turn the switch to the “DC” side.
* Video Iris Lens [3-pin terminal] * DC Iris Lens [4-pin plug]
4. If the cable is too long, house it in the camera mounting bracket.

Back Focus Adjustment
Back Focus Adjustment
The back focus has been factory-adjusted to the best point for CS-mount lens, but it may need to be re-
adjusted if the mount is changed to the C-mount or when a different lens is used.
If required, adjust it as follows.
- With a fixed-focus lens
If the focus can not be adjusted correctly by rotating the lens focus ring, adjust the back focus as
follows.
1. Loosen the back focus locking screw by turning it counterclockwise with a screwdriver.
2. Turn the back focus adjustment ring to focus at the best point.
3. Tighten the back focus locking screw by turning its clockwise.
- With a zoom lens
If the image is out of focus when zooming (with-angle telephoto), adjust the camera as follows.
1. Shoot a comparatively dark scene with thin lines about three meters away from the came.
2. Set the lens to the maximum telephoto position, and adjust the lens focus.
3. Set the lens to the maximum wide-angle position, and adjust the focus.
4. Repeat step 2 and 3 two or three times.
