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.
Due to design modification, data given in this instruction book are subject to possible change
without prior notice.
PRECAUTIONS
• Picture may not appear correctly if white-spot correction is performed incorrectly. Follow the
steps listed in the instructions. (Reference: White-spot correction
∆
I) Do not perform this op-
eration when there are no white spots.
• 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.
•
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.
•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 the C-
mount 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.
*4 pin plug, service part number: SCV2859-001
For details, please consult your JVC dealer.
CONNECTION
1. When the camera is powered, the POWER LED lights up.
U/E only: Installing the ferrite core
To retain electromagnetic compatibility, use the ferrite core provided when connecting to the power source.
* Install the ferrite cores within 50 mm of the camera-side connectors.
•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.
EG only: When you use this camera, the socket - outlet must be installed near the equipment to
make disconnect on easily.
2. Connect to a video monitor, etc. (751)
3. To install the camera onto a tripod, fixing unit, or pan/tilt unit, use the fall-preventive
socket (d) shown in the illustration.
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.
4. 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 (e) from the bottom of the camera by removing
two fixing screws as shown w. Attach the CAMERA MOUNTING BRACKET (e) 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 (e); longer type screws (over 5mm)
may damage inner components.
(This camera is used indoor and under similar conditions.)
Fall Prevention
•Exercise maximum caution when installing the unit to the wall or ceiling. You 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.
•
As a failsafe against falling, attach the unit by chain, wire cable or other safety restraint to an appropri-
ate anchor point. Attach the fall prevention wire using the black screw on the upper surface 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-C920: M2.6 × 4 mm, TK-C921: M3 × 6 mm)
Never use any screw longer than the specified length as the inside can be damaged.
