䢇
Do not subject the lens to strong light source such as sun
rays. This may cause the equipment to malfunction.
䢇
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.
䢇
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.
䢇
When automatic iris is selected and AGC is ON, even if
the iris setting is changed using the Iris Control button, the
Increase Sensitivity 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.
䢇
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.
䢇
When this camera is used in the White Balance ATW-N,
ATW-W (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.
䢇
If a high brightness object (such as a lamp) is shot, the
image on the screen may have white vertical tailings. This
phenomenon (smear) is characteristic of solid-state image
sensors and is not a malfunction.
䢇
The electronic shutter of this unit is set to 1/50 seconds by
default. Use the remote control unit to change the
electronic shutter to 1/120 seconds under fluorescent
lighting in regions with commercial power of frequency 60
Hz. (Sensitivity level decreases slightly when this is set to
1/120 seconds.)
䢇
When the same position is monitored for 24 hours
continuously over a long period, the increased contact
resistance on the horizontal rotation section may cause
noise interferences in the images and operation from the
remote control unit may become unstable. Therefore, turn
off and on the system power once a week to initialize the
camera and clean the contact.
䢇
Do not touch the dome cover with your hands. Dirty
covers will cause image deterioration.
䢇
Do not subject the dome cover to strong impact. It may
result in damage and water seepage.
䢇
The dome cover may fog due to the drastic change of
temperature when humidity is high.
䢇
Do not connect an AC 24 V cable to AC 230 V power
supply. The camera will be damaged. If the wrong cable is
connected, the internal circuit will be damaged. Stop
using the camera and send it to your nearest JVC dealer
for repair. (Chargeable)
䢇
To supply AC 24 V, use a AC 24 V supplying power unit
that is insulated from AC 230 V line.
䢇
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 choose not to shoot the above area by
using the tilt limit settings (
䢇
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.
䢇
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.
䢇
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.
䢇
When you preset focus, we ask you to adjust under actual
usage temperature. If you feel unclear focus, please re-
preset focus.
䢇
Additionally, we recommend you to use either One Push
AF or Manual focus adjustment when you feel unclear
focus at your temperature environment.
Maintenance
䢇
Turn off the power before performing maintenance.
䢇
Wipe using a soft cloth. Wiping it with thinner or benzene
may melt the surface or cause it to fog. For tough stains,
wipe using a cloth that is dipped into a neutral detergent
diluted with water, followed by wiping with a dry cloth.
Saving Energy
䢇
When the camera is not in use for a long time, turn off the power
of the system for safety and energy conservation reasons.
