Precautions on handling
Precautions on transport
The projection lens is susceptible to vibrations and
impacts. Be sure to always remove the lens during
transport.
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 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-PKD75) (for low
ceiling: Model No. ET-PKD75S) and call a
specialized technician for installation.
Do not place the projector over 2 700 m
(8881.5') above sea level. When using it
over 1 400 m (4605.3') above sea level, set
the “Fan Control”, described on page 78,
to “HIGHLAND”.
Otherwise the life of the product may be shortened.
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.
Screen
If the screen has stains, flaws or discoloration,
clear images cannot be viewed. When handling
the screen, be careful not to apply volatile
substances or leave flaws or stains on the screen.
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.
Disposal
To discard the product, call the dealer or a specialized
dealer.
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.
