An appliance and cart combination should be moved with care. Quick stops, excessive force,

and uneven surfaces may cause the appliance and cart combination to overturn. 8. Slots and openings in the cabinet and the back or bottom are provided for ventilation, and to

insure reliable operation of the appliance and to protect it from overheating, these openings

must not be blocked or covered. The openings should never be blocked by placing the appliance on a bed, sofa, rug, or other similar surface. This appliance should never be placed near or over a radiator or heat register. This appliance should not be placed in a built-in installation such as a bookcase unless proper ventilation is provided.

9.This appliance should be operated only from the type of power source indicated on the marking label. If you are not sure of the type of power supplied to your home, consult your dealer or local power company. For appliance designed to operate from battery power, refer to the operating instructions.

10.This appliance system is equipped with a 3-wire grounding type plug (a plug having a third (grounding) pin). This plug will only fit into a grounding-type power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the grounding plug.

11.For added protection for this product during a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage to the product due to lightning and power-line surges.

12.Do not allow anything to rest on the power cord. Do not locate this appliance where the cord will be abused by persons walking on it.

13.Follow all warnings and instructions marked on the appliance.

14.Do not overload wall outlets and extension cords as this can result in fire or electric shock.

15.Never push objects of any kind into his appliance through cabinet slots as they mat touch dangerous voltage points or short out parts that could result in a fire or electric shock. Never spill liquid of any kind on the appliance.

16.Do not attempt to service this appliance yourself as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel.

17.Unplug his appliance from the wall outlet and refer servicing to qualified service personnel under following conditions:

a.When the power cord or plug is damaged or frayed.

b.If liquid has been spilled into the appliance.

c.If the appliance has been exposed to rain or water.

d.If the appliance does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions as improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the appliance to normal operation.

e.If the appliance has been dropped or the cabinet has been damaged.

f.When the appliance exhibits a distinct change in performance - this indicates a need for service.

18.When replacement parts are required, be sure the service technician has used replacement parts specified by the manufacturer that have the same characteristics as the original part. Unauthorized substitutions may result in fire, electric shock, or other hazards.

19.Upon completion of any service or repairs to this appliance, ask the service technician to perform routine safety checks to determine that the appliance is in safe operating condition.

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.

Information for USA

This device complies with Part 15 of the FCC Rules.

Changes or modifications not approved by JVC could void the user’s authority to operate the equipment.

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.

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 LENSA

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 B

 

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.

4. Installation of camera

 

 

E

 

• With the mounting plate on the underside

 

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

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 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.

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 F 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.
