When using multicast, make use of an
0
IGMPv2-compliant network switch.
Some switching hubs of products that are
0
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.
The electronic shutter of this product is set to
0
"1/30" by default. For regions with a commercial
power supply frequency of 50 Hz, switch to
"Flickerless" during use under fluorescent lights
(excluding inverter lighting equipment) to
prevent flickers.
The dark areas on the screen may appear grainy
0
or white spots may increase. 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.
If the power supply voltage is momentarily cut
0
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.
As the dome cover is of a semiglobular shape,
0
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 p.68 [ Tilt Limit ] )
When shooting objects with a luminance
0
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.
In particular, manual and auto pan operation
0
near the TELE end (telephoto side) may cause
the screen to vibrate (unsmooth rotation). This
is a feature of the motor and is not a malfunction.
As long magnification lens is used in this
0
product, the focus may be unclear due to
temperature changes but this is not a
malfunction.
Preset the focus under an environment with a
0
temperature closest to that in your actual usage.
If the temperature change is large and the focus
becomes unclear, preset the focus again before
using the product.
If you sense that the focus has become unclear
0
due to temperature changes, use the Auto
Focus function or reset the focus manually.
The time of the internal clock may be
0
significantly out of alignment if the power of the
product is turned off for a long time or when there
is prolonged power failure. If this occurs,
readjust the clock time.
(A p.79 [[Time] Page] )
While viewing with the Built-in Viewer, audio
0
sound may sometimes be out of
synchronization. This is not a malfunction.
The fan inside this unit is a consumable part. If
0
the fan stops running for some reasons, a
"Caution : The fan is stopped" message will be
displayed over the video. You can also set the
alarm trigger to send out a notification on fan
stoppage via mail or TCP.
(A p.56 [[Alarm] Page] )
If the fan stops functioning, turn off this unit and
0
consult our service center.

for a security alarm. Our company shall not be
liable for any inconveniences or damages
caused in the event of false detection or failure
to detect by these functions. We shall not be
liable for any inconveniences or damages
