Introduction
Storage and Location of Use
ⅷ Do not install this unit at the following
locations.
● Places that are exposed to vapor or oil, such
as kitchens.
● Places that exceed the ambient temperature
(-10 I to 50 I)
● Places at which corrosive gases are emitted
● Places at which radiation or X-rays and
strong radio waves or magnetism are emitted
● Places that are subject to vibration
ⅷ Using this unit or cables connected to this
unit at places at which strong radio waves
and magnetism are emitted (e.g. near a radio,
TV, transformer or motor) may give rise to
noises in the image and changes in its color.
ⅷ Do not install this unit at a place that is
directly exposed to cold air or near the outlet
of an air-conditioner. The dome cover may
become foggy when there is a drastic change
in temperature.
ⅷ Although this unit is IP66-compliant, water-
proof under all kinds of environment is not
guaranteed.
Others
ⅷ This unit comes with a built-in AGC circuit.
When using this unit with the AGC function
turned on, the sensitivity increases
automatically at a dark place and the screen
may appear grainy. This is not a malfunction.
ⅷ When using this unit in the White Balance
ATW (automatic tracking) mode, the color
tone may differ slightly from the actual color
according to the condition of the object due to
the principle of the automatic tracking white
balance circuit. This is not a malfunction.
ⅷ When shooting an object with high brightness
(lamps, etc.), vertical lines may appear in the
image on the screen (smear phenomenon)
and bleeding may be found around the high
brightness object (blooming phenomenon).
These are due to the characteristics of the
CCD and not malfunctions.
ⅷ Turning “ON” the simple DAY & NIGHT switch
switches the image to black-and-white at a
dark place. Sensitivity increases in the case
of black-and-white images. The screen may
therefore appear grainy and white spots may
increase. When switching between colored
and black-and-white images, the bright
portions of the screen are enhanced and the
clarity of the screen may deteriorate. This is
not a malfunction.
ⅷ When the source voltage cuts off or drops
during lightning or upon turning on the air-
conditioner, distortion or noise may occur in
the image.
ⅷ When this unit is moved from a cold to a
warm place, dew condensation may occur,
which may result in malfunctioning. In this
case, leave this unit at room temperature for
about 1 hour before turning on the power.
ⅷ The rotation angle of this unit has been
enlarged to enable installation at a wide
variety of locations. When the zoom function
of the lens is set to Wide and the tilt angle set
close to ±70°, a portion of this unit may be
visible on the shooting screen depending on
the rotation angle.
When this occurs, adjust the angle of view
accordingly. (A Pg. 22)
ⅷ To prevent fogging due to changes in
temperature, make sure to insert the supplied
silica gel into the designated location.
(A Pg. 21)
ⅷ When the supply voltage of the camera is
low, the input protection circuit within the
camera may be triggered and the power of
the camera may turn off automatically. Make
sure to use a power supply and voltage for
the camera that is within -10 % of the rated
voltage.
ⅷ All Interconnecting Equipment must be UL
Listed.
Maintenance
ⅷ Turn off the power before performing
maintenance.
ⅷ Clean the dome cover using a lens cleaning
cloth (or 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.
Energy Conservation
ⅷ When not in use, turn off the power of the
system to save energy.
