If a problem occurs (such as no image or no sound) or if you notice
smoke or a strange smell coming from the projector, turn off the power
and disconnect the power cord from the wall outlet.
* Do not continue to use the projector in such cases, otherwise fire or
electric shocks could result.
€ Check that no more smoke is coming out, and then contact an Authorised
Service Center for repairs.
€ Do not attempt to repair the projector yourself, as this can be dangerous.
Do not install this projector in a place which is not strong enough to

e If the installation location is not strong enough, it may fall down or tip over,
and severe injury or damage could result.
Installation work (such as ceiling suspension) should only be carried
out by a qualified technician.
e |f installation is not carried out correctly, there is the danger that injury or
electric shocks may occur.
If foreign objects or water get inside the projector, or if the projector is
dropped or the cabinet is broken, turn off the power and disconnect the
power cord from the wall outlet.
e Continued use of the projector in this condition may result in fire or electric
shocks.

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, use the accessory carrying bag.
When placing the projector inside the carrying bag, position it so
that the lens is facing upward.
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-PKC75). Furthermore, all
installation work should only be carried out by a qualified technician.
If using of this projector at high elevations (above 1400 m), consult
your dealer or Authorised Service Center.
Special measures will be necessary to use this projector at high elevations,
so consult your dealer or Authorised Service Center about preparations.
Failure to observe this may cause malfunctions.
Notes on use
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.
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, retract the lens and then cover it with the accessory lens cover.

About the screen
If the screen you are using is dirty, damaged or discoloured, attractive
projections cannot be obtained. Do not apply any volatile substances to the
Screen, and do not let it become dirty or damaged.
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.

Operating range
If the remote control unit is held so
that it is facing directly in front of the
front or rear remote control signal
receptors, the operating range is
within approximately 7 m (23^) from
the surfaces of the receptors.
Furthermore, the remote control unit
can be operated from an angle of
+30 ° to the left or right and +15 ?
above or below the receptors.
NOTE:
e if there are any obstacles in
between the remote control unit
and the receptors, the remote
control unit may not operate
correctly.
e |f strong light is allowed to shine
onto the remote control signal
receptor, correct remote control
operation may not be possible.
Place the projector as far away
from light sources as possible.
€ |f facing the remote control unit
toward the screen to operate the
projector, the operating range of
the remote control unit will be
limited by the amount of light
reflection loss caused by the
characteristics of the screen
used.

Connections
Notes on connections
* Read the instruction manual for each system component carefully before
connecting it.
€ Turn off the power supply for all components before making any
connections.
e If the cables necessary for connecting a component to the system are not
included with the component or available as an option, you may need to
fashion a cable to suit the component concerned.
e If there is a lot of jitter in the video signal which is input from the video
source, the picture on the screen may flicker. In such cases, it will be
necessary to connect a TBC (time base corrector).
