Precautions on handling

Cautions regarding transportation
Be sure to attach the lens cover before transporting
the projector.
The projection lens is extremely susceptible to vibration
and shocks. When carrying the projector, be careful not
to subject to excessive vibration or shock while under
transport.
Cautions regarding setting-up
Observe the following at all times when setting up the
projector.
Avoid setting up in places which are subject to
vibration or shocks.
If the projector is set up in locations with strong vibration,
such as near a motor, or if it is installed inside a vehicle or
on board a ship, the projector may be subjected to vibration
or shocks which can damage the internal parts and cause
malfunctions or accidents. Accordingly, set up the projector
in a place which is free from such vibrations and shocks.
Do not set up the projector near high-voltage power
lines or near motors.
The projector may be subject to electromagnetic
interference if it is set up near high-voltage power lines
or motors.
If installing the projector to the ceiling, ask a qualified
technician to carry out all installation work.
If the projector is to be suspended from the ceiling, you
will need to purchase the separate installation kit (Model
No.: ET-PKL6500/S). Furthermore, all installation work
should only be carried out by a qualified technician.
This product cannot be used at altitudes of 1,400 m or
more above sea level. If it is used as is, there may be
an adverse effect on component service life and so on.
Notes on use
If using this projector more than 8hours/day
(continuous operation), special measures will be
necessary to use this projector. Please consult your
dealer or Authorized Service Center about preparations.
In order to get the best picture quality
If outside light or light from indoor lamps is shining onto
the screen, the images projected will not have good
contrast. Draw curtains or blinds over any windows and
turn off any fluorescent lights near the screen to prevent
reflection.
Depending on the environment where used, hot air from
the cooling fan vent may in rare cases cause
disturbances on the screen.
Do not touch the surfaces of the lens with your bare hands.
If the surface of the lens becomes dirty from fingerprints
or anything else, this will be magnified and projected
onto the screen. Moreover, when not using the projector,
cover it with the accessory lens cover.

About the screen
If the screen you are using is dirty, damaged or
discolored, attractive projections cannot be obtained.
Do not apply any volatile substances to the screen, and
do not let it become dirty or damaged.
Lamp
A mercury lamp with high internal pressure is used as
the light source for this equipment. High-pressure
mercury lamps have the following characteristics.
• If the lamp deteriorates due to shock, scratching or the
passage of time during use, it may rupture with a loud
noise, or enter the unlit state and end its service life.
• Service life varies significantly due to individual lamp
differences and use conditions.
• Exceeding the replacement period will increase the
probability of rupture.
About the liquid crystal panel
The liquid crystal panel of the projector is built with very
high precision technology giving you fine picture details.
Occasionally, a few non-active pixels may appear on
the screen as a fixed point of blue, green or red.
Please note that this dose not affect the performance
of your LCD.
About optical parts
If the projector is subjected to a continuous use for more
than 6 hours every day, you may have to replace optical
parts, such as LCD panels or polarizers within less than
one year. When you use the projector in such a case, ask
your dealer or an Authorized Service Center for details.
Before carrying out cleaning and
maintenance, be sure to disconnect the
power cord plug from the wall outlet.
Wipe the cabinet with a soft, dry cloth.
If the cabinet is particularly dirty, soak the cloth in
water with a small amount of neutral detergent in it,
squeeze the cloth very well, and then wipe the
cabinet. After cleaning, wipe the cabinet dry with a
dry cloth.
If using a chemically-treated cloth, read the
instructions supplied with the cloth before use.
Do not wipe the lens with a cloth that is dusty or which
produces lint.
If any dust or lint gets onto the lens, such dust or lint
will be magnified and projected onto the screen. Use
a blower to clean any dust and lint from the lens
surface, or use a soft cloth to wipe off any dust or lint.
