Precautions on handling
Precautions on transport
Make absolutely sure that the lens cap is in place
when transporting the projector or carrying it
around. Both the projector and the projection lens
are precision-made and, as such, are susceptible to
vibration and impacts. When transporting the
projector and lens or carrying them around, place
them in the boxes in which they were housed at the
time of purchase, and take care to keep them away
from vibration and impacts.
Precautions on installation
Be sure to observe the following precautions when
installing the product.
Avoid installing the product in a place
exposed to vibrations or impacts.
If the projector is installed in a place where
vibrations are transmitted from a source of
driving power and others or mounted in a car or
a vessel, vibrations or impacts may be
transmitted to the product to damage the internal
parts, causing failure. Install the product in a
place free from vibrations and impacts.
Do not move the projector while it is
operating or subject it to vibration or
impact.
The service life of its internal motors may be
shortened.
Do not install the projector near high-
voltage power lines or power sources.
The product may be exposed to interference if it
is installed in the vicinity of high-voltage electrical
power lines or power sources.
Do not place the projector on a vinyl
sheet or carpet.
If a vinyl sheet sucked up and blocks the air filter
intake port, the internal temperature of the
projector may increase, which triggers the
protection circuit, turning off the power.
Be sure to ask a specialized technician
when to install the product to a ceiling.
If the product is to be installed hanging from the
ceiling, purchase an optional hanging attachment
(for high ceiling: Model No. ET-PKD35) (for low
ceiling: Model No. ET-PKD35S) and call a
specialized technician for installation.
Do not place the projector over 2 700 m
above sea level. When using it over
1 400 m above sea level, set the “Fan
Control1”, described on page 35, to
“HIGHLAND”.
Otherwise the life of the product may be
shortened.
Disposal
To discard the product, call the dealer or a
specialized dealer.
Precautions on use
To view clear images:
• The audience cannot enjoy high-contrast and
clear images if outside light or the illumination
interferes the screen surface. Draw window
curtains or blinds, turn off the lightings near the
screen or take other proper measures.
• In rare cases, wafture can occur on the screen
affected by the warm air from the exhaust port
depending on the environment.
Do not touch the surface of the
projection lens with bare hand.
If fingerprints or stains are left on the projection
lens surface, they are magnified and projected
on the screen. Keep your hands away from the
lens. Cover the lens with the supplied lens cap
when the projector is not used.
Lamp
A mercury lamp with high internal pressure is used
for the light source of this product. A high-pressure
mercury lamp has the following characteristics:
•
It may burst with a loud sound or end its life cycle
by not illuminating because of given impacts,
flaws, or deterioration due to used hours.
•
The life cycle of a mercury lamp varies according
to the individual difference or conditions of use.
In particular, turning the power on and off
frequently and/or repeatedly will greatly affect the
life cycle.
• In rare cases, it may burst shortly after the first
lighting.
• The possibility of burst increases when the
lamp is used beyond the replacement time.
Cleaning and maintenance
Be sure to remove the power cord plug from the
receptacle before cleaning.
Use soft and dry cloth to clean the cabinet
If stains are hard to remove, use a cloth
dampened with a kitchen detergent solution
(neutral) and squeezed to wipe the cabinet and
finish with a dry cloth. If a chemical wipe is used,
follow its instructions.
Do not clean the lens surface with fuzzy
or dusty cloth.
If dust adheres to the lens, it will be magnified
and projected on the screen.
Use a soft and clean cloth to wipe off dust.
