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 MOISTURE.
INFORMATION (FOR CANADA) RENSEIGNEMENT (POUR LE CANADA)
This Class [B] digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe [B] est conforme à la norme NMB-003 du Canada.
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 operation when there are no white spots.
• If the AGC switch is turned on, the sensitivity increases automatically in dark places. It is not a failure when the image looks grainy.
• If the D/N switch is turned on, the mode changes automatically to black and white in dark places. As the sensitivity increases, the image
may look grainy and white spots may appear. When changing modes, bright portions of image may be emphasized but this is not a
failure of the camera.
• 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.
OPERATING PRECAUTIONS
Storage and Location of Use
1. This camera has been designed for indoor use .When you use it outdoors, be sure to use a housing or the like.
2. DO not install or use the camera in the following places.
• In a place exposed to rain or moisture.
• In a place with vapor or oil, for example in a kitchen.
• When the ambient temperature rises above or falls below the acceptable range(from -10 °C to 50 °C)
• In a place at which corrosive gases are emitted.
• Near a source of radiation, X-rays, strong radio waves or magnetism.
• In a place subject to vibration.
• In a place with excessive dirt.
3. Using this unit or cables connected to this unit at places at which strong radio waves and magnetism are emitted (e. g. near a
radio, TV, transformer or motor)may give rise to noises in the image and changes in its color.
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
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: For details, please consult your JVC dealer.

LENS ADJUSTMENT
Video adjustment
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 unintention-
ally, 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.
