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 62 for details on compatible signals which can be input to the
projector.
B
Only one audio system circuit is available for the AUDIO IN L-R connectors, so if you
change the audio input source, you will need to remove and insert the appropriate plugs.

BRemove the battery if not using the remote control unit for long periods.
BUse only CR2025 batteries as replacement batteries.
BIf the remote control unit is held so that it is facing directly in front of the
remote control signal receptor, the operating range is within
approximately 7 m (23´) from the surfaces of the receptor. Furthermore,
the remote control unit can be operated from an angle of ±30° to the left
or right and ±15° above or below the receptor.
BIf the buttons on the remote control unit are kept pressed, the battery
power will be consumed rapidly.
BIf there are any obstacles in between the remote control unit and the
receptor, the remote control unit may not operate correctly.
BIf strong light is allowed to shine onto the remote control signal receptor,
correct projector operation may not be possible. Place the projector as
far away from light sources as possible.
B
If 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.

Correcting keystone distortion
Keystone distortion is corrected automatically when the projector’s automatic
setup function is used, but this correction will not apply if the screen itself is
tilted. In such cases, you can correct the keystone distortion manually with
the following procedure.
Vertical
keystone
distortion
correction
Operation
Press the HHbutton. Press the IIbutton.
KEYSTONE 0
NOTE:
BIf you press the AUTO SETUP button after correcting the keystone
distortion manually, the automatic keystone correction function will
operate and the corrected picture will return to its previous incorrect
condition. To prevent this from happening, you can set “AUTO
KEYSTN” in the “OPTION” menu to “OFF”. (Refer to page 45.)
BVertical keystone distortion can be corrected to ±30°of the angle of tilt.
However, the greater the correction amount, the more the picture
quality will deteriorate, and the harder it will become to achieve a good
level of focus. To obtain the best picture quality, set up the projector
and screen in such a way that the amount of keystone correction
required is as minimal as possible.
BThe picture size will also change when correction of keystone distortion
is carried out.
BThe ratio of length and width of an image may become incorrect
depending on the amount of the keystone correction.
BKeystone distortion of the on-screen display will not be corrected.
Vertical keystone distortion correction only.

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 power cord.
Be sure to disconnect the power
cord by following the procedure
given on page 26.
$Gently turn the projector
upside down, and then remove
the air filter cover.
NOTE:
BIf 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.
BDo not use detergent when
washing the air filter.
BIf 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:
BBe sure to install the air filter

Care and maintenance
Replacing the lamp unit
Warning
The lamp unit should only be
replaced by a qualified
technician.
When replacing the lamp, allow it
to cool for at least one hour
before handling it.
BThe lamp cover gets very hot,
and touching it can cause burns.
Notes on replacing the lamp
unit
BThe 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.
BDispose of the removed old lamp
with the same care that would be
taken with a fluorescent light.
BA 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:
BThe projector is not supplied
with a replacement lamp unit.
Please ask your dealer for
details. Lamp unit product
no.: ET-LAB10
CAUTION:
BDo not use any lamp unit other
than the one with the product
number indicated above.
NOTE:
BThe usage hours explained
above are for when “LAMP
POWER” in the “OPTION”
menu has been set to “HIGH”
and when “AI” in the
“PICTURE” menu has been set
to “OFF”. If “LAMP POWER” is
set to “LOW”, or “AI” is set to
“ON”, the life of the lamp can
be extended.

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 sur l’utilisation
Afin d’obtenir la meilleure qualité d’image
Fermer les rideaux ou les volets de toutes les fenêtres et éteindre les lampes
fluorescentes situées à proximité de l’écran afin que la lumière extérieure ou
la lumière des lampes intérieures n’éclaire pas l’écran.
Ne pas toucher aux surfaces de l’objectif avec les mains nues.
Si la surface de l’objectif est salie par des empreintes digitales ou autre, ceci
sera agrandi et projeté sur l’écran. Par ailleurs, lorsque le projecteur n’est
pas utilisé, rétracter l’objectif, puis la couvrir à l’aide du capuchon d’objectif.
Écran
N’appliquer aucun produit volatil qui risque de décolorer l’écran, et veiller à
ce que l’écran ne soit pas sale ou endommagé.

Remplacement du bloc de lampe
AVERTISSEMENT
Le bloc de lampe ne devrait être
remplacé que par un technicien
qualifié.
Lors du remplacement de la
lampe, la laisser refroidir pendant
au moins une heure avant de la
manipuler.
BLe couvercle de la lampe devient
très chaud, et on risque de se
brûler si on le touche.
Notes sur le remplacement
du bloc de lampe
BLa lampe produisant la lumière
est en verre; il ne faut donc pas la
laisser tomber ou la cogner
contre des objets rigides, car elle
risquerait d’éclater. Faire bien
attention lorsqu’on manipule la
lampe.
BJeter la lampe usagée de la
même manière qu’une lampe
fluorescente.
BIl faut utiliser un tournevis Phillips
pour déposer le bloc de lampe.
Période de remplacement du
bloc de lampe
La lampe est un produit qui doit être
remplacé. Même si la durée de vie
complète de l’ampoule n’est pas encore
épuisée, la luminosité de la lampe
diminuera progressivement. Il faut donc
remplacer périodiquement la lampe.
L’intervalle de remplacement de la
lampe prévu est de 2 000 heures; il
est toutefois possible qu’il faille
remplacer la lampe avant ce délai en
raison d’éléments variables comme
les caractéristiques particulières de la
lampe, les conditions d’utilisation et
l’environnement d’installation. Il est
recommandé de toujours avoir un bloc
de lampe de rechange prêt à l’emploi.
La lampe s’éteindra automatiquement
après environ 10 minutes lorsque la
limite de 2 000 heures d’utilisation est
atteinte, car le risque d’explosion de la
lampe devient beaucoup plus grand
passé cette limite.
REMARQUE:
BLe projecteur n’est pas fourni
avec un bloc de lampe de
rechange. Demander les
détails au revendeur. Numéro
de produit du bloc de lampe:
