Others
● This camera has a built-in AGC circuit. Setting AGC
to "Mid" or "High" increases the sensitivity of a dark
image, and the screen may appear grainy. This is not
a malfunction.
FOR USA AND CANADA
● This installation should be made by a qualified service
person and should conform to all local codes.
● Use of this camera and cables connected to this
camera at locations where strong electrical or
magnetic waves are generated (e.g. near a radio, TV,
transformer, monitor, etc.) may result in images being
affected by noise interference or colors being changed.
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
● When this camera is used with the white balance set to
"ATW" (Auto Tracking White Balance), the color tone
of some objects may differ slightly from the actual color
due to the principle of the automatic tracking white
balance circuit. This is not a malfunction.
● This installation shall be in accordance with the
National Electrical Code, ANSI/NFPA 70. The unit is to
be powered by a Listed Class 2 power supply or using
the PoE.
CAUTION: TO REDUCE THE RISK OF ELECTRICK
SHOCK. DO NOT REMOVE COVER
● Do not install this camera at locations where cold
air is circulated, such as near the air vent of an air
conditioner. The drastic change in temperature may
fog up the dome cover.
● The AC 24 V power supply should conform to the
following: Class 2 only (For USA), Isolated power
supply only (For Europe and other).
(OR BACK). NO USER-SERVICEABLE
PARTS INSIDE. REFER SERVICING TO
QUALIFIED SERVICE PERSONNEL.
● For regions with a commercial power frequency of
50 Hz, switch to the Flickerless mode during use
under fluorescent lights (excluding inverter lighting
equipment) to prevent flickers.
● Any Mention in this manual of Alarm inputs have not
been evaluated by UL to be used for Burglar Alarm
Functionality.
The lightning flash wish arrowhead symbol, within
an equilateral triangle is intended to alert the
user to the presence of uninsulated "dangerous
voltage" within the product's enclosure that age"
within the product's enclosure that may be of
sufficient magnitude to constitute a risk of electric
shock to persons.
● Do not install this camera at a location that traps heat.
This camera discharges heat from the surface of the
main unit. Do not install it at locations that may trap
heat, such as wall corners.
● When the electronic sensitivity enhancement feature
is enabled, the screen may appear grainy and more
white spots may appear because the sensitivity has
increased. However, this is not a malfunction.
● Special technique is required when installing this
product.
Please refer to your dealer for installation.
Handling Precautions
● If the power supply voltage is momentarily cut off or
reduced due to lightning or the power supply to the
air conditioner being turned on, the image may be
disrupted or noise interference may occur.
● Rating label is pasted at the bottom or top of the
camera unit.
● Do not block the vents.
The exclamation point within an equilateral
triangle is intended to alert the user to
the presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance.
Inadequate heat ventilation may cause this camera to
malfunction. Be sure not to block the vents around the
camera.
● JVC is not liable for any compensation if you drop the
camera due to insecure mounting by not following the
installation description. Pay careful attention during
installation.
● The rotation angle of this camera is increased to
enable installation at a wider variety of locations. When
the lens is at the wide-angle position, and tilted at an
angle close to +/-80 degrees, a part of the camera
may come into view on the screen depending on the
rotation angle. When this occurs, adjust the field angle
accordingly.
