ⅷ
Do not subject the lens to strong light source such
as sun rays. This may cause the equipment to
malfunction.
ⅷ
This camera comes with a built-in AGC circuit. The
sensitivity increases automatically at a dark place
and the screen may appear grainy. This is not a
malfunction.
ⅷ
While AGC is activated, if a transceiver which
causes strong electromagnetic wave is used near
the camera, the picture may suffer from beat.
Please use the camera more than three meters
away from such transceivers.
ⅷ
When automatic iris is selected, the Iris Control
button may not work depending on the brightness
of the screen (when the amount of light is not
sufficient). In this case, set the iris to Manual.
ⅷ
When automatic iris is selected and AGC is ON,
even if the iris setting can be changed with the Iris
Control button, the Sense Up function will be
enabled and the brightness of the screen may not
change. In this case, set AGC to OFF or set the iris
to Manual.
ⅷ
When this camera is used in the White Balance
A
ATW-Narrow
B
,
A
ATW- Wi de
B
(automatic
adjustment) mode, the color tone may differ
slightly from the actual color due to the principle of
the automatic tracking white balance circuit. This is
not a malfunction.
ⅷ
If a high luminance object (such as a lamp) is shot,
a white smear may appear at the upper and lower
ends of this object on the screen. This
phenomenon (smear) is characteristic of solid-
state image sensors and is not a malfunction.
ⅷ
Do not touch the dome cover with your hands.
Dirty covers will cause image deterioration.
ⅷ
Do not subject the dome cover to strong impact. It
may result in damage and water seepage.
ⅷ
The dome cover may fog due to the drastic change
of temperature when humidity is high.
ⅷ
Do not connect an AC 24 V cable to AC110 V/AC
230 V power supply. The camera internal circuit
will be damaged. Do not use the camera. Bring it
to your nearest JVC dealer for repair (charged
separately).
ⅷ
To supply AC 24 V, use a AC 24 V supplying power
unit that is insulated from AC 110 V /AC 230 V line.
ⅷ
When using multicast, make use of a IGMPv2-
compliant network switch.
ⅷ
Some hubs/switches of products that are equipped
with intelligent features may include a broadcast/
multicast suppression function. Viewing of
multicast images on this product may fail if this
function is enabled.
ⅷ
The electronic shutter of this product is set to 1/60
by default. For regions with a commercial power
supply frequency of 50 Hz, switch to the 1/100
during use under fluorescent lights (excluding
inverter lighting equipment) to prevent flickers.
ⅷ
When the B&W mode is set to
A
Auto
B
, the image
turns black-and-white in a dark location. As the
sensitivity level is increased in this case, the
screen may appear grainy and more white spots
may appear. When switching between color and
black-and-white images, the brighter area on the
screen is emphasized, which may reduce the
visibility. However, this is not a malfunction.
ⅷ
If the power supply voltage is momentarily cut off
or reduced due to lightning or turning on of the air
conditioner’s power, the image may be disrupted
or noise interference may occur.
ⅷ
As the dome cover is of a semiglobular shape,
image distortion will occur at the hemispherical
edge. When the hemispherical edge of this unit is
masked and horizontal level is shot in a tilt
direction, the hemispherical edge will enter the
field angle. This may cause the upper edge of the
screen to become black and the focus unclear. In
this case, you can avoid shooting the above area
by using the tilt limit settings (
A
Page 57).
ⅷ
When shooting objects with a luminance
difference or near a light source, ghost may occur
on the screen. This is a feature of the dome cover
and the built-in lens, and is not a malfunction.
ⅷ
In particular, manual and auto pan operation near
the TELE edge (telephoto side) may cause the
screen to vibrate (unsmooth rotation). This is a
feature of the motor and is not a malfunction.
ⅷ
Long magnification zoom lens embedded into this
product.
Although the focus might be slightly
unclear depending on the drastic change of
temperature, it will not be a malfunction.
ⅷ
When you preset focus, we ask you to adjust
under actual usage temperature.
If you feel
unclear focus, please re-preset focus.
ⅷ
Additionally, we recommend you to use either One
Push AF or Manual focus
adjustment when you
feel unclear focus at your temperature
environment.
