COLOR VIDEO CAMERA

Instructions

Thank you for purchasing the JVC color video camera.

To obtain the best results from your new camera, read these instructions carefully before use;

retain the manual for future reference.

WARNING:

TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS UNIT TO RAIN OR MOIS-

TURE.

PRECAUTIONS

· If an AGC switch is turned on, the sensitivity increases automatically in dark places. It is not a

failure when the image looks grainy.

· Before mounting the camera, first mount the lens to be used with the camera, and then operate

it in order to check the back focus.

· If a high-intensity object (such as a lamp) is in shot, the image on the screen may have vertical

lines (smear) or blur (blooming) at its periphery (especially in AES mode). This is a characteristic

of the CCD, and is not a defect.

· If a DC auto iris lens is used or if the appliance is operated under a fluorescent light, the automatic

electronic switch (AES) should be set to OFF. If set to ON, flickering may occur. If a manual iris

lens is used, set the AES to ON.

· When used in hot places, vertical lines may appear on the screen of this camera. This is a

characteristic of the CCD and not a failure of the camera.

· The automatic tracking system may not function properly when shooting with non-standard

lighting or lighting with a color temperature which exceeds the capability of the camera.

· If the camera subject is a single solid color (other than white), the auto white circuit will normally

attempt to change this color to white. In the case of this camera, if it cannot make a correct

prediction, the previous white balance setting will be maintained until the subject colors become

more varied.

· This unit assumes that the light source being used is either natural lighting (sunlight) or

incandescent lamps (color temperature 2300 K-10000 K). Under special light sources, such as

sodium lamps, colors may appear different compared to what is visible to the eye.

· Noise may appear in the picture and/or the colors may be incorrect if the camera is used near a

radio or television transmitting antenna, in places where strong electromagnetic waves are

generated by transformers, motors, etc., or near devices emitting radio waves, such as

transceivers or cellular phones.

· This unit accepts only a DC iris lens.

·To save energy, be sure to turn off the system when not in use.

MOUNTING A LENS

1. Before mounting a lens, check whether it is a C-mount or CS-mount lens.

If a C-Mount lens is used, loosen the back-focus locking screw (M 2.6) using a Phillips

head screwdriver, turn the back-focus adjusting ring with your fingers or the screw-

driver and change the mounting method.

2. Dimension (b) of the lens shown in the illustration must be as shown in the table

below. If (b) exceeds the value in the table, it may damage the inside of the camera

or correct mounting may be impossible; never use such lenses. Do not attach a C-

mount lens when using the CS-mount.

The F mark indicates a focal point.

3. Mount the DC IRIS lens on the camera by turning the lens clockwise. Adjust its

position.

4. If the lens has an auto-iris mechanism, connect the lens cable after checking the pin

assignment.

3. When mounting the camera on a fixer, pan/tilt, etc., use the camera mounting screw

hole (d) located on the camera-mounting bracket.

CAUTION: Use a screw shorter in length than 7mm from the camera-mounting face.

Furthermore, make use of the rotation prevention holes (e) to prevent the camera

from falling and be sure to mount the camera securely.

Special precautions must be taken when mounting the camera on a wall or a ceiling.

JVC is not liable for any damage caused by incorrect installation.

4. Installation of camera

· With the mounting plate on the underside

This camera is originally designed to be mounted from underneath, as shown

The hole is standard photographic pan-head screw size (1/4-20 UNC, as is found

in a typical camera fixing point or pan & tilt head.

· With the mounting plate relocated to the topside

Remove the CAMERA MOUNTING BRACKET (f) from the underside of the camera

by removing the two fixing screws as shown

w. Attach the CAMERA MOUNTING

BRACKET (f) to the top, then mount the camera on the Fixing Unit as shown

Make sure that two original screws are used when mounting the CAMERA

MOUNTING BRACKET (f). Be sure to use a 6 mm long locking screw for the camera-

mounting bracket.

These instructions assume the camera will only be mounted indoors.

Fall Prevention

·Exercise maximum caution when installing the unit to a wall or ceiling. If in any doubt

ask a professional to do the job, because if the unit were subsequently to fall, it could

result in personal injuries or accidents.

· When installing the unit on a fixer, turn table, etc., be sure to install it firmly and to

use one of the rotation-preventing holes (e) provided.

· As a failsafe against falling, attach the unit by chain, wire cable or other safety restraint to

an appropriate anchor point. Attach the fall prevention wire using the black screw on the

upper surface (TK-C751 : on the rear panel) of the camera as shown in figure F. When

changing the side at which CAMERA MOUNTING BRACKET is installed, be sure to

change the attachment side of the fall prevention wire also to the appropriate side.

· Specified screw (TK-C750 : M2.6

= 4 mm, TK-C751 : M3 = 6 mm )

Never use any screw longer than the specified length as the inside can be damaged.

LENS ADJUSTMENT

Video adjust

A readjustment might be necessary depending on the configuration of the shooting object or the

lens installed. To perform a readjustment, the AGC switch on the back of the unit should be turned

OFF before adjusting the LEVEL.Turn the AGC on again when the adjustment has been completed.

· LEVEL adjustment

· If the sensitivity adjustment LEVEL is turned too far to L, the sensitivity will increase due to the

AGC function of the camera, making the image look grainy.

Back focus adjustment

Back focus has been optimally adjusted at the factory for CS-mount lenses, but it may

need re-adjustment if the mount is changed for C-mount lenses. If required, adjust 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 anti-clockwise (

) with a screwdriver.

2. Point the camera at a test pattern.

3. Turn the lens focus ring to

4. Turn the back focus adjustment ring to find optimum focus.

5. Tighten the back focus locking screw by turning it clockwise (

· With a zoom lens

If the lens does not track (loses focus) at any point in the zoom range, adjust as follows:

1. Loosen the back focus locking screw by turning it anti-clockwise (

) with a screwdriver.

2. Point the camera at a comparatively dark scene with thin lines.

3. Set the lens to the maximum telephoto position, and adjust the lens focus.

4. Set the lens to the maximum wide-angle position, and turn the back focus ring to adjust the

focus.

(Repeat steps 2 and 3 two or three times.)

5. Tighten the back focus locking screw by turning it clockwise (

Set this switch to ON for strongly backlit subjects.

AES (Automatic Electronic Shutter)

Turning this switch

5 "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 bright-

ness of the subject.

Hunting may occur at a certain object brightness due to the mechanism of the AES circuit, but

this is not a fault.
