OPERATING PRECAUTIONS
■
The camera does not have a power switch
Power turns on as soon as the power cord is plugged
into a power outlet. Before cleaning the camera,
unplug the power cord from the power outlet.
■
What to do if OVER HEAT appears on the display
This message indicates that the interior of the camera
has become very hot. Immediately unplug the power
cord from the power outlet, and contact a qualified
service person or system installer.
■
Note the following to ensure long-term trouble-
free operation
Long operation under high temperatures and high
humidity can cause components to deteriorate and
shorten camera life.
The recommended ambient operation temperature is
less than +35 °C.
Make sure the camera is installed in a location where it
is not directly exposed to heat from a radiator, heater,
etc.
■
Avoid use of this camera in a food preparation
area and other locations where there are large
amounts of steam vapour and oil.
■
About the Camera Cleaning Function
Prolonged use can lead to noise on the monitor and
divergence of preset positions.
If such conditions persist even after you perform
camera cleaning (page 35), use the special setup
menu to execute the “REFRESH” operation (page 39).
■
This camera is designed for use in a hanging
configuration only.
Do not use it in an upright configuration on a tabletop,
floor, etc. Such conditions create the risk of
malfunction.
■
CCD colour filter burn-in
Intense light concentrated on one spot for a long
period can cause deterioration of the CCD internal
colour filters, and discoloration of the affected part.
Even if the camera position is changed from a fixed
position, the discoloration at the previous location of
the concentrated light will remain on the screen.
■
Do not point the camera at a strong light source.
Intense light such as that produced by a spotlight
concentrated on one part of the screen can cause
blooming (rainbow around the strong light) or smearing
(vertical stripes above and below the strong light).
■
Do not aim the camera at the same object for a
long time.
Burn-in of an image may be caused on the fluorescent
screen of CRT.
■
Handle the camera carefully.
Do not drop the camera, or subject it to strong impact
or vibration. Such conditions create the risk of
malfunction.
■
Do not allow the camera to become wet.
Make sure that it is not exposed directly to water. Such
conditions create the risk of malfunction.
■
Condensation inside of the dome cover
Remove the dome cover and use a soft cloth to wipe
off the moisture (page 10).
■
Consumables
Parts having contacts such as the lens-drive motors,
cooling fan motor and slip-rings inside the camera are
subject to wear with time. Please ask the nearest
service centre about replacement and maintenance of
such parts.
■
Cleaning the camera
Turn off the camera and wipe it with a soft cloth. If the
camera is very dirty, wipe it off gently with a soft cloth
moistened with a weak solution of water and a neutral
kitchen detergent. Wring all excess liquid from the
cloth before wiping the camera. Next, wipe off all
remaining solution with a soft, dry cloth.
A dirty dome cover or lens causes deterioration of
picture quality. Use lens cleaning paper (like the type
available for cleaning eyeglasses or a camera lens) to
clean the lens.
The dome cover is particularly susceptible to damage.
Gently wipe it with a soft cloth.
