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 installing 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-PKD56H) (for low ceiling: Model
No. ET-PKD55S). Please call a specialized technician or
contact an Authorized Service Centre for installation.
Install the projector so that it will be
supported only by its bottom panel and
by none of its other parts or surfaces.
Do not place the projector over 2 700 m
above sea level. When using it over 1 400
m above sea level, set the “ALTITUDE”,
described on page 36, to “HIGH”.
Otherwise the life of the product may be shortened. When
using it over 2 700 m above sea level, consult your dealer.
Lens Focus
Do not adjust the lens focus in the initial period
(within approx. 30 minutes) after switching the
projector on. The high clarity projector lens is
thermally affected by the light from the light source,
making the focus unstable in the period just after
switching on. Please allow a warm-up time of at
least 30 minutes before adjusting the lens focus.
Failure to do so may cause heating focus drift.
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.
• Depending on where the projector is used,
there are rare occasions when hot air from the
air exhaust vents or the warm air from air
conditioning can cause a shimmering effect on
the screen. For this reason, take care not to
shield the air exhaust vents and consider the
direction of the air flowing from air conditioning.
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.
• If the lamp bursts, gas inside the lamp is
released and smoke may appear.
•
Lamp deterioration accelerates when used
continuously for 24 hours or more. Lamp
deterioration due to continuous use can be
reduced by using the “LAMP RELAY” function.
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.
