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 Centre.
Special measures will be necessary to use this projector at high elevations,
so consult your dealer or Authorised Service Centre about preparations.
Failure to observe this may cause malfunctions.
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.
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.

AUTO
(S-VIDEO only)
When an S1 video signal is input to
the S-VIDEO terminal, the aspect
ratio is changed automatically to
project a 16:9 picture.
4:3
The input signal is projected without
change.
16:9
The picture is compressed to a ratio
of 16:9 and projected.
S4:3
The size of the input signal is
compressed to 75% and projected.
(This is useful for projecting a
picture with a 4:3 aspect ratio onto a
16:9 screen.)
S1 video signals
B S1 video signals are a type of video
signal with an aspect ratio of 16:9
which include a detector signal. This
detector signal is output by some
sources such as wide-vision video
decks. If the AUTO setting above is
selected, this projector will recognise
the detector signal and automatically
switch the aspect ratio to 16:9 in
order to project the picture.
NOTE:
B This projector is equipped with an
aspect ratio selection function.
However, if a mode which does not
match the aspect ratio of the input
signal is selected, it may affect the
quality of viewing of the original
picture. Keep this in mind when
selecting the aspect ratio.
B If using this projector in places such
as cafes or hotels with the aim of
displaying programmes for viewing
for a commercial purpose or for
public presentation, note that if the
aspect ratio (16:9) selection function
is used to change the aspect ratio of
the screen picture, you may be
infringing the rights of the original
copyright owner for that programme
under copyright protection laws.
B If a normal (4:3) picture which was
not originally intended for widescreen viewing is projected onto a
wide screen, distortion may occur
around the edges of the picture so
that part of the picture is no longer
visible. Such programmes should be
viewed in 4:3 mode to give proper
consideration to the aims and
intentions of the original programme’s
creator.
RESIZING
This should normally be set to “ON”.
(This setting is only for signals
which have lower resolutions than
the LCD panels. Refer to page 52
for details.)
ON
The pixel resolution of the input
signal is converted to the same
resolution as the LCD panels before
being projected. For signals with

Cleaning and replacing the air filter
Replacing the lamp unit
If the air filter becomes clogged with dust, the internal temperature of the
projector will rise, the TEMP indicator will flash and the projector power will
turn off. The air filter should be cleaned every 100 hours of use,
depending on the location where the projector is being used.
Warning
# Turn off the MAIN POWER
switch and disconnect the
power cord plug from the wall
outlet.
Turn off the MAIN POWER switch
according to the procedure given
in “Turning off the power” on
page 25 before disconnecting the
plug from the wall outlet.
$ Gently turn the projector
upside down.
NOTE:
B Place the projector on top of a
soft cloth so that it will not
become scratched.
% Remove the air filter.
Put your fingernails under the air
filter and pull the air filter out of
the projector.
& Clean the air filter.
Use a vacuum cleaner to clean
off any accumulated dust.
Notes on replacing the
lamp unit
NOTE:
B Be careful not to let the air filter
get sucked into the vacuum
cleaner.
' Install the air filter.
NOTE:
B Be sure to install the air filter
cover before using the projector.
If the projector is used without the
air filter cover installed, dust and
other foreign particles will be
drawn into the projector, and
malfunctions will result.
B If the dust cannot be removed by
cleaning, it is time to replace the
air filter. Please consult your
dealer. Furthermore, if the lamp
unit is being replaced, replace the
air filter at this time also.
B The light generating lamp is
made of glass, so dropping it or
allowing it to hit hard objects may
cause it to burst. Be careful when
handling the lamp.
B After having removed the old
lamp, carelessly discarding it can
cause the lamp to burst. Dispose
of the lamp with the same care
that would be taken with a
fluorescent light.
B A Phillips screwdriver is
necessary for removing the lamp
unit. Make sure that your hands
are not slippery when using the
screwdriver.
NOTE:
B The projector is not supplied with
a replacement lamp unit. Please
ask your dealer for details. Lamp
unit product no.: ET-LAC75
CAUTION:
B Do not use any lamp unit other
than the one with the product
number indicated above.
The lamp is a consumable product.
Even when the full life of the bulb
has not been exhausted, the
brightness of the light will gradually
decline. Therefore periodic
replacement of the lamp is
necessary.
The intended lamp replacement
interval is 2000 hours, but it is
possible that the lamp may need to
be replaced earlier due to variables
such as a particular lamp's
characteristics, usage conditions
and the installation environment.
Early preparation for lamp
replacement is encouraged.
A lamp that has exceeded 2000
hours of use has a much greater
chance of exploding. In order to
prevent the lamp from exploding,
the lamp will be automatically shut
off when 2000 hours of use have
been reached.
NOTE:
B The usage hours explained
above are for use when the HIGH
setting has been selected for
LAMP POWER in the OPTION2
menu. If the STANDARD setting
is selected, the brightness of the
lamp will be less and life of the
lamp can be extended.
B While 2000 hours is the intended
replacement interval, it is not a
period of time covered by
warranty.
