The symbol is intended to alert the user to the presence of

uninsulated “dangerous voltage” within the product’s

enclosure that may be of sufficient magnitude to constitute

a risk of electric shock to persons.

CAUTION:

To prevent electric shocks

and risk of fire hazards, do

NOT use other than specified

power source.

Warning -- This equipment has been tested and found to comply with

the limits for a Class A digital device, pursuant to part 15

of the FCC Rules. These limits are designed to provide

reasonable protection against harmful interference when

the equipment is operated in a commercial environment.

This equipment generates, uses, and can radiate radio

frequency energy and, if not installed and used in

accordance with the instruction manual, may cause

harmful interference to radio communications. Operation

of this equipment in a residential area is likely to cause

harmful interference in which case the user will be

required to correct the interference at his own expense.

Caution -- Any changes or modifications in construction of this

device which are not expressly approved by the party

responsible for compliance could void the user’s authority

to operate the equipment.

lPi?ECAUTlONS

Do not attempt to disassemble the camera.

In order to

prevent electric shock, do not remove screws or cover.

There are no user-serviceable parts inside.

Refer all servicing to qualified service personnel.

Handle the camera with care.

The camera could be damaged by improper handling or storage.

Do not expose the camera to rain or moisture, or try to operate it in

wet areas.

Take immediate action if the camera becomes wet. Turn the

power off and refer servicing to qualified service personnel.

Moisture can damage the camera and also create a danger of

electric shock.

Do not use strong or abrasive detergents when cleaning the

camera body.

Use a dry cloth to clean the camera when dirty.

Backlight compensation (BLC) ON/OFF switch

If the subject you wish to view is too dim because of a bright

background, set the BLC switch to ON to compensate for the bright

background.

With BLC on, the background brightness may saturate in some

cases. This function may not operate properly if the object is too

small compared to the area of the background. This function can

be used with either the linear shutter(EE mode) or an autoiris

lens(Al lens mode).

CONNECTORS AND CONTROLS

EEIAI Switch

This switch is used to select EE (electronic exposure or

ELC-

electronic light control) mode or Al (autoiris lens or ALC-automatic

light control) mode.

In the EE mode, a continuously variable electronic shutter is

employed to automatically control the exposure time of the CCD

image sensor according to the incoming light level. With this mode

selected, a fixed or manual iris lens can be used instead of an

autoiris

lens. In the Al mode, the CCD shutter speed is fixed to

l/60(1/50)

set, and the incoming light level is controlled by the

autoiris lens.

To use a video-drive type or the DC-drive type of autoiris lens, set

this switch to the Al position.

Cautions :

1. Under bright lighting conditions such as outdoors, use an

autoiris lens because the ELC control range is not wide enough

under these conditions.

2. Under certain unique lighting conditions, the following

phenomena may appear:

. Strong smear and/or blooming on highlight objects such as

spotlights or windows.

. Noticeable flicker in the picture and/or color rendition

variations.

To avoid this, use an autoiris lens.

3. When operating in EE mode with a manual iris lens, the depth of

field of the image may be less than that obtained by using an

ALC lens. Depth of field varies inversely with the iris opening.

Thus, using this camera in EE mode with the manual iris lens

fully opened may result in less depth of field and the distant

objects in picture may be seen out of focus.

4. Fixed iris or manual iris lenses may be used with the linear

shutter (EE mode) where the scene brightness varies over a

limited range.

5. Do not use the EE mode when an autoiris lens is installed.

ICONNECTORS

AND CONTROLS

AGC ON/OFF switch

This switch is provided for the AGC circuit.

The AGC circuit incorporated into the camera boosts the sensitivity

automatically when the scene illumination is insufficient.

INTlLL

switch

This camera can operate independently, using its internal

crystal-

controlled sync generator, or it may be synchronized, usually

known as line-locking.

To select one or the other of these sync

modes, set the DIP switch on the rear panel to either LL or INT.

If line-locking is selected, all the cameras in the system must be

adjusted to begin the video field scan at the same time. This is

described in the following procedure.(g)

V-phase adjustment potentiometer

This potentiometer is set fully counterclockwise at the factory.

If two or more cameras are connected to a switcher and the picture

on the monitor rolls while switching from camera A to B, adjusting

the vertical phase (V-phase) of the cameras will probably eliminate

the rolling. If this adjustment is necessary, it should only be

performed by a qualified technician.

Before making any adjustment, confirm that cameras A and B

are connected to the power supply with the same polarity.

To make an adjustment, follow the steps below.

1. While observing the video output signals from both cameras on

an oscilloscope, turn camera A’s V-phase

control (on back of camera) until vertical

sync from both cameras are in phase. “V-phase” control

2. If camera A’s adjustment range is (variable resistor)

insufficient, adjust camera B’s V-phase

control in the opposite direction to

camera A until they are in phase.

3. If these adjustments do not bring vertical

sync from both cameras in phase, recheck the

polarity of the power supply connections. V-phase

If no oscilloscope is available, a less accurate adjustment can be made

by observing the monitor and adjusting the V-phase potentiometer until

no roll occurs on the monitor when switching back and forth between

cameras A and B.
