Notes on use
In order to get the best picture quality
Draw curtains or blinds over any windows and turn off any lights near the
screen to prevent outside light or light from indoor lamps from shining onto
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.
Screen
Do not apply any volatile substances which may cause discolouration to the
screen, and do not let it become dirty or damaged.
Lamp
The lamp may need to be replaced earlier due to variables such as individual
lamp characteristics, usage conditions and the installation environment,
especially when the projector is subjected to continuous use for more than
10 hours or the power is frequently turned on and off.
Liquid crystal panel
The liquid crystal panel of the projector is built with very high precision
technology to provide fine picture details. Occasionally, a few non-active
pixels may appear on the screen as fixed points of blue, green or red.

Notes on connections
B Read the instruction manual for each peripheral device carefully before
connecting it.
B Turn off the power supply for all peripheral devices before making any
connections.
B If the cables necessary for connection are not included with the peripheral
device or available as an option, you may need to prepare a proper cable
for the device concerned.
B If there is a lot of jitter in the video signal, the projected image may flicker.
In such cases, it will be necessary to connect a TBC (time base corrector).
B Refer to the list on page 68 for details on compatible signals which can be
input to the projector.
B Only one audio system circuit is available for each of the PC AUDIO IN
and AUDIO IN L-R connectors, so if you change the audio input source,
you will need to remove and insert the appropriate plugs.

RESIZING
(S-VIDEO/VIDEO/RGB/YP
BPR only)
This should normally be set to “ON”.
(This setting is only for signals
which have lower resolutions than
the LCD panels. Refer to page 68
for details.)
ON
The pixel resolution of the input
signal is converted to the same
resolution as the LCD panels before
being projected.
This may sometimes cause
problems with the quality of the
picture.
OFF
The input signal is projected at its
original resolution, with no pixel
conversion. The projected picture
will be smaller than normal, so
adjust the zoom setting or move the
projector forwards or backwards to
adjust the picture size if necessary.
If set to “OFF”, some features, such
as “DIGITAL ZOOM”, “REALTIME
KEYSTONE”, “KEYSTONE” or
“INDEX WINDOW” will not function.
FRAME LOCK
(RGB only)
If the picture’s condition is bad while
an RGB moving picture is projected,
set “FRAME LOCK” to “ON”. Refer
to page 68 for compatible RGB
signals.
NOTE:
B If using this projector in places
such as cafes or hotels to
display programmes 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 4:3 picture is projected
onto a 16:9 screen, distortion
may occur around the edges of
the picture so that part of the
picture is no longer visible.
Programmes which have 4:3
aspect ratios should be viewed
in 4:3 mode to give proper
consideration to the aims and
intentions of the original
programme’s creator.

Care and maintenance
Cleaning and replacing the air filter
If the air filter becomes clogged with dust, the internal temperature of the
projector will rise, the TEMP indicator will illuminate and the projector’s
power will turn off (the TEMP indicator will flash after the power is turned off).
The air filter should be cleaned every 100 hours of use.
% Replace the air filter, and then
install the air filter cover.
Cleaning
Use a vacuum cleaner to clean off
any accumulated dust.
Replacement procedure
# Turn off the power and
disconnect the mains lead.
Be sure to disconnect the mains
lead by following the procedure
given on page 28.
$ Gently turn the projector
upside down, and then remove
the air filter cover.
NOTE:
B If the dust cannot be cleaned
by a vacuum cleaner, remove
the air filter and soak it in
water, and then wash out the
dust by hand. Be sure to install
the air filter after it has dried.
B Do not use detergent when
washing the air filter.
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.
NOTE:
B Be sure to install the air filter
before using the projector. If
the projector is used without
the air filter installed, dust and
other foreign particles will be
drawn into the projector, and
malfunctions will result.

Replacing the lamp unit
Warning
When replacing the lamp, allow it
to cool for at least one hour
before handling it.
B The lamp cover gets very hot,
and touching it can cause burns.
Notes on replacing the lamp
unit
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 Dispose of the removed old lamp
with the same care that would be
taken with a fluorescent light.
B A Phillips screwdriver is
necessary for removing the lamp
unit.
Lamp unit replacement
period
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 2 000 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.
The lamp will automatically shut off
after approximately 10 minutes
when 2 000 hours of use have been
reached because of a much greater
chance of it exploding after this
time.
NOTE:
B The projector is not supplied
with a replacement lamp unit.
Please ask your dealer for
details. Lamp unit product
no.: ET-LAB50
CAUTION:
B Do not use any lamp unit other
than the one with the product
number indicated above.
NOTE:
B The usage hours explained
above are for when “LAMP
POWER” in the “OPTION”
menu has been set to
“STANDARD” and when “AI” in
the “PICTURE” menu has
been set to “OFF”. If “LAMP
POWER” is set to “ECOMODE”, or “AI” is set to “ON”,
the life of the lamp can be
extended.
B While 2 000 hours is the
intended replacement interval,
it is not a period of time
covered by warranty.

Projection dimensions calculation methods
If the screen size (diagonal) is SD (m), then the following formula is used to
calculate the projection distance for the wide lens position (LW) and the
projection distance for the telephoto lens position (LT).

LW/ LT

SH
NOTE:
B If 4:3 images are projected onto a 16:9 screen that
has been set using the projection distance for a
16:9 screen, the 4:3 images will overflow the
screen at the top and bottom. In such cases, set
“ASPECT” to “S4:3”. (Refer to page 46 for details.)
*The values obtained from the formulas above are approximate.
For 16:9 aspect ratios, the following formula can be used to calculate the
projection distance.
LW=0.0307xSD/0.0254-0.031
LT=0.0371xSD/0.0254-0.029
LW=0.0304xSD/0.0254-0.029
