These are general IMPORTANT SAFEGUARDS and certain items
may not apply to all appliances.

8. Slots and openings in the cabinet and the back or bottom are pro-
vided for ventilation, and to insure reliable operation of the appli-
ance and to protect it from overheating, these openings must not be
blocked or covered. The openings should never be blocked by plac-
ing 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 in-
stallation 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, un-
plug it form 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.
II

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 this appliance through cabinet
slots as they may 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 re-
moving covers may expose you to dangerous voltage or other haz-
ards. Refer all servicing to qualified service personnel.
17. Unplug this appliance from the wall outlet and refer servicing to
qualified service personnel under the 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 oper-
ating instructions. Adjust only those controls that are covered by
the operating instructions as improper adjustment of other con-
trols may result in damage and will often require extensive work
by a qualified technician to restore the appliance to normal op-
eration.
e. If the appliance has been dropped or the cabinet has been dam-
aged.
f. When the appliance exhibits a distinct change in performance -
this indicates a need for service.
III

Thank you for purchasing this product.
(These instrustions are for TK-WD310U and TK-WD310E.)
Before beginning to operate this unit, please read the instruction
manual carefully in order to make sure that the best possible per-
formance is obtained.
Features
䡵Backlight compensation over a wide area is realized by the 14-bit
Wide Dynamic Range feature.
The Wide Dynamic Range feature controls the exposure time using
a maximum of 5 sampling timing for the image within a single screen.
Even when shooting in areas with large difference in lightning, sub-
jects with difference in brightness can be viewed in a clear and natu-
ral state.
䡵1/3-inch high-resolution DPS device adopted as shooting element
to realize high picture quality with no smearing or blooming in areas
with high luminance. In addition, 1.9lx (during F1.2, 50%, AGC HIGH
setting) is realized for minimum subject brightness.
䡵Horizontal resolution of 480 lines (typ.) and vertical resolution of over
400 lines allow display of finely detailed video.
䡵New device adopted for use even under strong electric field condi-
tions.
䡵Compatible with CS mount and VIDEO auto iris/DC auto iris.
*When using the C mount lens, C mount adapter is required.
䡵Various settings in each menu screen are possible.
Menu settings can be performed easily using single button opera-
tions.
䡵3 white balance modes of ATW, AWB and MANUAL are available.
ATW mode that adjusts the white balance automatically according
to the changes in lighting conditions (color temperature) or AWB/
MANUAL mode that automatically or manually adjusts and locks the
white balance of specific lighting conditions can be selected.
䡵Camera title setting and display can be made.
䡵Compact design allows installation in narrow spaces.

Operating Precautions
●To save energy, when it is not being used turn the system’s power
off.
●This camera has been designed for indoor use.
When you use it outdoors, be sure to use an appropriate housing.
●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 soot, for example in a kitchen.
•When the ambient temperature rises above or falls below the ac-
ceptable range (from –10°C to 50°C).
•Near a source of radiation, X-rays, strong radio waves or magne-
tism.
•In a place where corrosive gasses are generated.
•In a place subject to vibration.
•In a place with excessive dirt.
●If this camera and the cables connected to this camera are used
where there are strong electromagnetic waves or where there is
magnetism present, for example near a radio or TV transmitter, power
transformer or an electric motor, the picture may produce noise and
the colours may be affected.
●This camera incorporates an AGC circuit. As a result, when it is
used under low light conditions, the camera sensitivity is automati-
cally boosted and the picture may look uneven. However, this is not
a malfunction.
●When this camera is used in the ATW mode, the recorded colours
may be slightly different from the actual colours due to the opera-
tional principles of the auto-tracking white balance circuit. However,
this is not a malfunction.
●Hunting may occur depending on the used lens. However, this is not
a malfunction of the unit.
●The screen surroundings may appear dark depending on the used
lens.
INTRODUCTION

Operating Precautions (continued)
●The white balance (ATW) of this device is optimally set for sunlight.
Proper white balance may not be achieved for artificial lighting such
as fluorescent lighting, etc.
●If you use this camera in locations where the camera is exposed to
fluorescent light, a slow color change may occur.
(White balance normal = 5,400 K, range is 2,500 K to 10,000 K.)
●AGC HIGH(×2) and up: in this mode, ATW white balance may be
inaccurate.
●White balance performance decreases under poor lighting condi-
tions.
●Observe the following when carrying out camera maintenance.
•Turn the power OFF before proceeding to carry out maintenance.
If it is contaminated seriously, clean the contaminated part with a
cloth (or a tissue) which has been soaked in a solution of water and
a neutral detergent.
●The unit is to be powered by a DC 12 V or an AC 24 V power supply.
The AC 24 V power supply should conform to the following:
U type : Class 2 only
E type : Isolated power supply only
●The beat may sometimes appear on the screen if gain is raised
when the line lock is in use, but the phenomenon takes place due to
the fluctuation of power frequency and is not a malfunction.
●At Low light levels, video iris lens may “Hunt”. Please adjust iris
level on lens to minimise hunting.
●Recommended range of operating temperature is 0°C to 35°C de-
grees. The camera will function outside these parameters to –10°C
to 50°C degrees. But processing errors may be apparent.
●Line-Lock is set for 50 Hz ±0.02 Hz. If line frequency is outside this
tolerance, picture may jitter and some interference may be visible in
high contrast scenes.
●At low light level, when the slow shutter functions the screen may be
tinted.

●Blemishes: Small spots are normal, the camera contains compen-
sation functions for blemishes above 120 mV (p-p) in value. Please
contact your JVC authorised dealer for further information.
●For temperatures higher than the recommended temperature, the
slow shutter may not work correctly.
