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 T O RAIN OR MOISTURE.

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.

• If a zoom lens is used, check the back focus before mounting the camera. This also applies to
lens ALC and LEVEL. (See the instructions on lenses for details.)

• If a high-intensity object (such as a lamp) is 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 an EE lens is used, set the automatic electronic shutter switch (AES) 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. In such
a case, set to the

“MANU” position.

• 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.

• Where there are strong electromagnetic waves or magnetism, for example near a radio or TV
transmitter, transformer , motor , etc., the picture may contain noise and the colors may be incorrect.

• Beware of the instruction of noise when installing the twisted pair cable that is used as a
connection.

• 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 screw­driver 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 the C­mount lens when using a CS-mount.

The F mark indicates a focal point.

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

4. 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.

5. If the lens has an auto-iris mechanism, connect the lens cable after checking the pin
arrangement.
If the lens cable has a different type of plug, use the 4PIN PLUG supplied.

CONNECTION

1. When the camera is powered, the POWER LED lights up.

• Never connect the DC 12V and AC 24V power inputs simultaneously.

• Be sure to observe the correct +,

– polarity when connecting a DC 12V power input.

2. Connect the VIDEO OUT +/- terminals, which are on the rear panel, to the +/- terminals
on the receiver using twisted pair cable.

3. MONITOR Terminal
The MONITOR Terminal is for connecting to a video monitor. The MONITOR Termi­nal is used for adjustment of screen framing.

*The VIDEO OUT and MONITOR Terminal cannot be used simultaneously.

4. 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 the screw with a length shorter than 7mm from a camera-mount-

ing face.

Furthermore, make use of the rotation prevention hole (e) to prevent the camera
from falling and securely mount the camera.
Special precautions must be taken for mounting the camera on a wall or a ceiling.
We are not liable for any damage caused by improper installation.

5. Installation of camera

• Mounting from the bottom

This camera is originally designed to be mounted from the bottom, as shown q.
The hole is standard photographic pan-head screw size (1/4-20 UNC). Example
the Fixing unit or Pan/Tilt unit.

• Mounting from the top

Remove the CAMERA MOUNTING BRACKET (f) from the bottom of the camera by removing
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 e. 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.
(This camera is used indoor and under similar conditions.)

Fall Prevention

• Exercise maximum caution when installing the unit to the wall or ceiling. Y ou should
not engage in the installation work yourself. Ask a professional to do the job, since
the fall of the unit can result in injuries and accidents.

• When installing the unit on a fixer, turn table, etc., make sure to install it firmly using
a rotation-preventing hole provided to prevent fall.

• To prevent fall, connect the unit to a section with sufficient strength (ceiling slab or channel)
using a fall prevention wire such as a wire chain and the like. Use the screw hole on the back of
the unit for installation.
Pay utmost attention to the length of the wire, too.

• Specified screw (M3 × 6 mm)
Be sure to attach the fall prevention wire by securing it with the screw that is provided
for that purpose on the rear panel.

LENS ADJUSTMENT

Video adjust

Connect the camera according to the connection method, turn it on, display an image on the
monitor, and check the image. The camera has been factory-adjusted to the best position, but it
may need to be adjusted according to the object conditions or combination of lenses. If the image
is unnatural, adjust it as follows:

• LEVEL adjustment

• ALC adjustment

• If the sensitivity adjustment LEVEL is turned excessively to L, the sensitivity increases be­cause of the AGC function of the camera, and the image looks grainy.

• If the video iris lens is set to too low a level, malfunction such as the hunting phenomenon, in
which the iris opens or closes unintentionally, may occur.
In such a case, first set LEVEL potentiometer on the lens to the H (iris open) position then
adjust it to the optimum level.

Back focus adjustment

The back focus has been 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 if 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 counterclocckwise (

) with a screwdriver.

2. Shoot a pattern closely.

3. Turn the lens focus ring to ∞.

4. Turn the back focus adjustment ring to focus at the best point.

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

).

• With a zoom lens

If the image is out of focus when zooming (telephoto wide-angle), adjust the camera as follows:

1. Loosen the back focus locking screw by turning it counterclocckwise (

) with a screwdriver.

2. Shoot 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 (

).

SETTING SWITCH

Line Lock

T o set the camera in LL mode for synchronization with the power supply frequency , take the follow­ing steps:

1. Turn switch r to “LL”;

2. Turn switch e to “PHASE”;

3. Press the + or – button

w to make the phase variable.
Adjust with the button w so that the vertical phase of the camera matches the vertical phase of
another camera (or system) with a multi-channel oscilloscope.
For initial setting, press RESET button q.

TK-C720TPU: 60Hz power region only
TK-C720TPE: 50Hz power region only

White Balance

White balance can be adjusted within the scope of 2900K to 8000K color temperature. When
switch t is at “AUTO”, the white balance is adjusted automatically.
For manual adjustment, take the following steps:

1. Turn switch t to “MANUAL”;

2. Turn switch e to “WHT.BAL”;

3. Pressing “R” button

w increases redness while pressing

“B” button

w increases blueness. For
initial setting, press RESET button q.
There are cases sometimes when the white balance cannot be adjusted manually for artifical
lights such as fluorescent lights, etc.

BLC (Back Light Compensation)

The switch y improves an image that is darkened because of backlighting.
Set this switch to ON for backlight subjects.

AES (Automatic Electronic Shutter)

Turning this switch u "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 i is turned on.

Hunting may occur at a certain object brightness due to the mechanism of the AES circuit, but
this is not a fault.

AGC (Automatic Gain Control)

The switch i automatically increases the camera

’

s sensitivity when the level of ambient light
drops.
ON: AGC is activated.
OFF: AGC is not activated.
