Connections
Before connection to the projector
Read and follow the operating and connecting instructions of each peripheral device.
The peripheral devices must be turned off.
Use cables that match each peripheral device to be connected.
If the input signal is affected by signal jitter, the projected image may have poor image quality and timebase
correction is effective.
Confirm the type of video signals. See “List of compatible signals” on page 44.
Only one audio system circuit is available for each of the COMPUTER 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.
If the signal cables are disconnected or if the power supply for the computer or video deck is turned off while
“DIGITAL ZOOM” or “INDEX-WINDOW” is being used, these functions will be canceled.
See “Enlarging the centered area” on page 26.

Settings
NOTE:
• You can correct the distortion ± 30 degrees from the
plane. For a better quality image, installing the projector
with a minimum of distortion is recommended.
• The distortion of the Main menu screen is not
correctable.
• The result of the keystone correction will affect the
aspect ratio and the size of the image.
• You can correct the keystone distortion manually when
“REALTIME KEYSTONE” is set to “ON”.
However, when you turn on the power, the amount of
correction will be reset and “REALTIME KEYSTONE”
will function again if the tilt is different from the last time
you used the projector. If you correct the keystone
distortion manually when “REALTIME KEYSTONE” is
set to “OFF”, the amount of correction will be stored by
the projector even after the power is turned off.
CLOCK PHASE

Care and Replacement
Cleaning the projector
J Before cleaning the projector
Disconnect the power cord plug from the wall outlet.
Unplug all the cables from the projector.
J Cleaning the outer surface of the projector
Wipe off dirt and dust gently with a soft cloth.
If it is difficult to remove the dirt, soak a cloth in a neutral detergent diluted with water, wring the cloth well
and then wipe the projector. Dry off the projector with dry cloth.
If you use a chemical treated wipe, follow the instructions supplied with it.
J Cleaning the lens
Wipe off dirt and dust gently with a lint-free cloth.
Make sure no dirt or dust remains on the surface of the lens. It will be enlarged and projected onto a
screen.
J Cleaning 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.
Use a vacuum cleaner to clean off any accumulated dust.
NOTE:
• 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.
• Do not use detergent when washing the air filter.
• 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.
Replacing the air filter
J Before replacing the Air filter
Maintenance
Disconnect the power cord plug from the wall outlet.

Replacing the Lamp unit
J Before replacing the Lamp unit
Disconnect the power cord plug from the wall outlet.
Make sure the Lamp unit and the surroundings are cooled enough.
Prepare a Phillips-head screwdriver.
Contact an Authorised Service Center to purchase a replacement Lamp unit (ET-LAB50).
When the projector is mounted in the ceiling, do not work directly under the projector or put your face closer
to the projector.
NOTE:
• Prior to replacing the lamp unit, allow it to cool down to prevent the risk of burns, damage and other hazards.
• Do not attempt replacement with an unauthorised lamp unit.
J When to replace the Lamp unit
The Lamp unit 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.

and when “AI” in the “PICTURE” menu has been set to “OFF”. If “LAMP POWER” is set to “ECO-MODE”, or “AI” is set to
“ON”, the life of the lamp can be extended.
• While 2 000 hours is the intended replacement interval, it is not a period of time covered by warranty.
J Replacement procedure
NOTE:
• If the lamp usage time has passed 2 000 hours (when “LAMP POWER” has een set to “STANDARD” and when “AI” has
been set to “OFF”), the projector will switch to standby mode after approximately 10 minutes of operation. The steps 7 to
12 should thus be completed within 10 minutes.
1. Disconnect the Power cord from the projector (See “Power cord” on page 20), and check that the area around
the Lamp unit has cooled down.

ont d'exploser ou de fuir, ce qui peut causer un
incendie, des blessures ou une contamination du
logement des piles et de la zone environnante.
Utiliser uniquement les piles spécifiées.
Si l'on insère des piles d'un type différent, elles ris-
queront d'exploser ou de fuir, ce qui peut causer un
incendie, des blessures ou une contamination du
logement des piles et de la zone environnante.
Ne pas mélanger des piles usées et des piles
neuves.
Si l'on insère les piles incorrectement, elles risquer-
ont d'exploser ou de fuir, ce qui peut causer un

Si de la poussière s'accumule sur la fiche du cordon
d'alimentation, l'humidité ainsi créée risquera
d'endommager l'isolation, ce qui peut provoquer un
incendie.
Le fait de laisser les piles à l'intérieur de la télécom-
mande pendant trop longtemps en cas d'inactivité risque de causer une dégradation de l'isolation, une
fuite de courant ou même des explosions, ce qui
pourrait causer un incendie.
Ne pas peser de tout son poids sur ce projecteur.
On risque de tomber ou de casser l'appareil, ce qui
peut causer des blessures.
Veiller tout particulièrement à ce que les enfants ne
se tiennent pas debout ou ne s'asseyent pas sur le

mande pendant une longue période, cela risque de
provoquer des fuites, une hausse anormale de la
température interne ou une explosion.
Si la lampe s'est cassée, ventiler immédiatement la
pièce. Ne pas toucher ni approcher le visage des
morceaux cassés.
Le non respect de cette consigne peut entraîner
l'absorption du gaz par l'utilisateur. Ce gaz se dégage
lorsque la lampe est cassée et il contient presque
autant de mercure qu'une lampe fluorescente, de
plus les morceaux cassés peuvent provoquer des
blessures.
Si vous pensez avoir inhalé du gaz ou que du gaz a
pénétré dans votre bouche ou dans vos yeux, contactez un médecin immédiatement.
S'adresser au revendeur pour le remplacement de la
lampe et l'inspection de l'intérieur du projecteur.
Débrancher la fiche du cordon d'alimentation de la
prise de courant comme mesure de sécurité avant
d'effectuer tout nettoyage.
