Precautions with regard to safety  
Do not mix old and new batteries.  
 If the batteries are inserted incorrectly, they may  
explode or leak, and fire, injury or contamination of  
the battery compartment and surrounding area may  
result.  
Disconnect the power cord plug from the wall outlet  
as a safety precaution before carrying out any  
cleaning.  
 Electric shocks can result if this is not done.  
If the lamp has broken, ventilate the room  
immediately. Do not touch or bring your face close  
to the broken pieces.  
Remove the used batteries from the remote control  
promptly.  
 If you leave used batteries in the remote control for  
an extended period of time, it may cause liquid  
leaking, abnormal internal temperature rising or  
explosion.  
 Failure to observe this may cause the user to absorb  
the gas which was released when the lamp broke and  
which contains nearly the same amount of mercury  
as fluorescent lamps, and the broken pieces may  
cause injury.  
If not using the projector for an extended period of  
time, disconnect the power cord plug from the wall  
outlet and remove the batteries from the remote  
control.  
 If dust builds up on the power cord plug, the resulting  
humidity may damage the insulation, which could  
result in fire.  
 Keeping or leaving the remote control with batteries  
inside may cause insulation deterioration, electrical  
leakage or explosion which could result in fire.  
 If you believe that you have absorbed the gas or that  
the gas has got into your eyes or mouth, seek  
medical advice immediately.  
 Ask your dealer about the replacement of the lamp  
unit and check the inside of the projector.  
Ask an Authorised Service Center to clean inside the  
projector at least once a year.  
 If dust is left to build up inside the projector without  
being cleaned out, it can result in fire or problems  
with operation.  
Do not put your weight on this projector.  
 You could fall or the projector could break, and injury  
may result.  
 Be especially careful not to let young children stand  
or sit on the projector.  
 It is a good idea to clean the inside of the projector  
before the season for humid weather arrives. Ask  
your nearest Authorised Service Center to clean the  
projector when required. Please discuss with the  
Authorised Service Center regarding cleaning costs.  
We are constantly making efforts to preserve and maintain a clean environment. Please take non repairable  
units back to your dealer or a recycling company.

Precautions with regard to safety  
Cautions on use  
In order to get the best picture quality  
Screen  
 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 apply any volatile substances which may  
cause discoloration to the screen, and do not let it  
become dirty or damaged.  
Do not touch the surfaces of the lens with your bare  
hands.  
The projector has a high pressure mercury lamp and  
that is characterized as follows.  
 If the surface of the lens becomes dirty from  
fingerprints or anything else, this will be magnified  
and projected onto the screen.  
 The brightness of the lamp depends on the duration  
of use.  
 The lamp may explode or shorten the lamp life by  
shocks or chipping damage.  
 The lamp may explode only occasionally after using  
the projector.  
 The lamp may explode if using the projector after the  
instructed lamp replacement timing.  
Liquid crystal panel  
 Do not project the same image for long periods of  
time, as this may remain as an afterimage on the  
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 stuck pixels may appear  
on the screen as fixed points of blue, green or red. It  
is recommended to switch off the projector once and  
try after 1hour later again. Please note that this does  
not affect the performance of your LCD.  
 The lamp life is depends on individual lamp  
characteristics, usage condition and the installation  
environment. Especially the consecutive use of the  
projector for more than 10 hours, or the frequent  
switching on or off may greatly affect on the lamp life.  
Optical components  
 If you use the projector consecutively 6 hours every  
day, the optical components may need to be replaced  
in less than 1 year.

KEYSTONE  
This projector detects its own degree of tilt and corrects  
the keystone distortion automatically (“REALTIME  
KEYSTONE”). However, keystone distortion may still  
affect the images in some cases (e.g. when the projector  
is tilted slightly and the tilt is corrected slowly by hand or  
when the screen itself is tilted). In such cases, set  
REALTIME KEYSTONE” to “OFF” and correct the  
vertical keystone distortion manually.  
NOTE:  
• If the projecting signal’s dot clock frequency is higher  
than 100 MHz, the adjustment may not make a  
difference.

Operation  
DOT CLOCK needs to be adjusted before adjusting the

If you require further adjustment for the same reason as  
the DOT CLOCK adjustment, you can fine adjust the  
timing of the clock. Press I H to adjust.  
NOTE:  
• If the projecting signal’s dot clock frequency is higher  
than 100 MHz, the adjustment may not make a  
difference.  
CLOCK PHASE is available with PC signals and the  
following COMPONENT connection.  
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.  
ASPECT  
(S-VIDEO/VIDEO/480i, 576i, 480p and 576p  
COMPONENT signals only)  
You can switch the aspect ratio manually when needed.  
Press I H to cycle through the options.  
• 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.

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.  
Air filter cover  
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  
  Disconnect the power cord plug from the wall outlet.  
J Replacement procedure  
1. Gently turn the projector upside down.  
2. Remove the Air filter cover.

Care and Replacement  
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.

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.

Précautions de sécurité  
Ne pas toucher le liquide provenant des fuites des  
piles.  
Ne pas placer les mains ou autres objets près de  
l'orifice de sortie d'air.  
 Si vous touchez le liquide des fuites, cela pourrait  
abîmer votre peau. Enlever le liquide a l'eau claire et  
rechercher immédiatement le secours d'un médecin.  
 Si vous recevez du liquide des fuites dans les yeux,  
cela pourrait provoquer la cécité ou des blessures.  
Ne pas vous frotter les yeux, enlever le liquide a l'eau  
claire et rechercher immédiatement le secours d'un  
médecin.  
 De l'air chaud sort par l'orifice de sortie d'air. Ne pas  
placer les mains, le visage ou d'autres objets qui ne  
peuvent résister à la chaleur près de cette sortie d'air  
[laisser un espace d'au moins 15 cm], sinon des  
brûlures ou des dommages risqueraient de  
s'ensuivre.  
Le remplacement de la lampe ne doit être effectué  
que par un technicien qualifié.  
Pendant un orage, ne pas toucher le projecteur ou le  
câble.  
 Il y a risque d'électrocution.  
 La lampe a une pression interne élevée. Si elle est  
manipulée incorrectement, une explosion peut  
s'ensuivre.  
 La lampe peut être facilement endommagée si elle  
est heurtée contre des objets durs ou si on la laisse  
tomber et des blessures et des mauvais fonctionne-  
ments peuvent s'ensuivre.  
Ne pas utiliser l'appareil dans un bain ou une  
douche.  
 Il y a risque d'incendie ou d'électrocution.  
Veillez à ce que le faisceau lumineux n'éclaire pas di-  
rectement votre peau pendant que vous utilisez le  
projecteur.  
 Une lumière intense est émise par l'objectif du projec-  
teur. Si vous vous placez dans ce faisceau lumineux,  
celui-ci risquera de vous blesser ou de vous abîmer  
la peau.  
Lors du remplacement de la lampe, la laisser re-  
froidir pendant au moins une heure avant de la ma-  
nipuler.  
 Le couvercle de la lampe devient très chaud, et on  
risque de se brûler si on le touche.  
Avant de remplacer la lampe, veiller à débrancher la  
fiche du cordon d'alimentation de la prise de cou-  
rant.  
Ne pas regarder directement dans l'objectif pendant  
que le projecteur fonctionne.  
 Une lumière intense est émise par l'objectif du projec-  
teur. Si l'on regarde directement dans cette lumière,  
elle risque de causer des blessures et de graves  
lésions aux yeux.  
 Veiller particulièrement à ce que les enfants ne regar-  
dent pas dans l'objectif. En outre, éteindre le project-  
eur si on le laisse sans surveillance.  
 Il y a risque d'électrocution ou d'explosion.  
Ne pas laisser des enfants ou des animaux domes-  
tiques toucher la télécommande.  
 Après avoir utilisé la télécommande, la ranger hors  
de portée des enfants ou des animaux domestiques.  
MISES EN GARDE  
Ne pas obstruer les orifices d'entrée et de sortie  
d'air.  
Ne pas installer le projecteur dans un environne-  
ment a haute température, tel qu'a proximité d'un  
chauffage ou en plein soleil.  
 Sinon cela peut causer un incendie, un dysfonction-  
nement ou une détérioration du plastique.  
 Cela risque de faire surchauffer le projecteur, et  
causer un incendie ou endommager le projecteur.  
 Ne pas installer le projecteur dans des endroits  
étroits, mal ventilés tels que des placards ou des  
étagères.  
 Ne pas placer le projecteur sur des tissus ou du  
papier, ces matériaux peuvent être aspirés dans l'ori-  
fice d'entrée d'air.  
Pour débrancher le cordon d'alimentation, tenir la  
fiche et non pas le cordon.  
 Si le cordon d'alimentation est tiré, le cordon sera  
endommagé et cela peut causer un incendie, des  
courts-circuits ou des chocs électriques sérieux.  
Débrancher toujours tous les câbles avant de dé-  
placer le projecteur.  
 Le fait de déplacer le projecteur avec des câbles  
branchés peut endommager les câbles, ce qui pour-  
rait causer un incendie ou des chocs électriques.  
Ne pas placer d'objets lourds sur le projecteur.  
 Cela peut déséquilibrer le projecteur et le faire  
tomber, ce qui peut entraîner des dommages ou des  
blessures.  
Ne pas court-circuiter, chauffer ou démonter les  
piles, et ne pas les mettre dans l'eau ou dans le feu.  
 Sinon, les piles risqueront de surchauffer, de fuir,  
d'exploser ou de prendre feu, et donc de causer des  
brûlures ou d'autres blessures.  
Ne pas installer le projecteur dans des endroits hu-  
mides ou poussiéreux ou dans des endroits où le  
projecteur peut entrer en contact avec des fumées  
grasses ou de la vapeur.  
 L'utilisation du projecteur dans de telles conditions  
peut causer un incendie, des chocs électriques ou  
une détérioration du boîtier en plastique. Une détério-  
ration du plastique risquerait en effet d'entraîner une  
chute du projecteur en cas d'installation au plafond.

Précautions de sécurité  
Lorsqu'on insère les piles, veiller à ce que les polar- Retirer rapidement les piles de la télécommande.  
ités (+ et –) soient bien respectées.  
 Si vous laissez des pile usagées dans la télécom-  
mande pendant une longue période, cela risque de  
provoquer des fuites, une hausse anormale de la  
température interne ou une explosion.  
 Si l'on insère les piles incorrectement, elles risquer-  
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.  
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, con-  
tactez un médecin immédiatement.  
 S'adresser au revendeur pour le remplacement de la  
lampe et l'inspection de l'intérieur du projecteur.  
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  
incendie, des blessures ou une contamination du  
logement des piles et de la zone environnante.  
Si l'on n'utilise pas le projecteur pendant une péri-  
ode prolongée, débrancher la fiche du cordon  
d'alimentation de la prise de courant et retirer les  
piles de la télécommande.  
 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 ris-  
que de causer une dégradation de l'isolation, une  
fuite de courant ou même des explosions, ce qui  
pourrait causer un incendie.  
Débrancher la fiche du cordon d'alimentation de la  
prise de courant comme mesure de sécurité avant  
d'effectuer tout nettoyage.  
 Sinon cela peut causer des chocs électriques.  
Demander à un centre technique agréé de nettoyer  
l'intérieur du projecteur au moins une fois par an.  
 S'il n'est pas nettoyé et que de la poussière s'accu-  
mule à l'intérieur du projecteur, cela peut causer un  
incendie ou des problèmes de fonctionnement.  
 Il est recommandé de nettoyer l'intérieur du project-  
eur avant l'arrivée de la saison humide. Demander au  
centre technique agréé le plus proche de nettoyer le  
projecteur lorsque cela est requis. Se renseigner  
auprès du centre technique agréé pour le coût du  
nettoyage.  
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  
projecteur.  
Nous faisons tous les efforts possibles afin de préserver l'environnement. Prière de rapporter l'appareil, s'il  
n'est pas réparable, à votre revendeur ou à un centre de recyclage.

d'alimentation électrique à haute tension ou de mo-  
teurs.  
 Le projecteur peut être soumis à des interférences  
électromagnétiques.  
Précautions lors de l'utilisation  
Afin d'obtenir la meilleure qualité d'image  
 Fermer les rideaux ou les volets de toutes les fenê-  
tres 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.  
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.  
Le projecteur possede une lampe au mercure a  
haute pression interne avec les caractéristiques sui-  
vantes.  
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, celles-ci seraient agrandies et pro-  
jetées sur l'écran.  
 La luminosité de la lampe dépend de la durée d'utili-  
sation.  
 Des chocs ou des écaillages sur la lampe pourraient  
la faire exploser ou écourter la durée de vie de la  
lampe.  
 La lampe pourrait exploser occasionnellement apres  
l'utilisation du projecteur.  
 La lampe pourrait exploser si le projecteur est utilisé  
apres le délai conseillé de remplacement de la  
lampe.  
 La durée de vie de la lampe dépend des caractéris-  
tiques individuels de la lampe, des conditions d'utili-  
sation et de l'environnement d'installation.  
L'utilisation consécutive pendant plus de 10 heures  
du projecteur ou de la commutation fréquente peu-  
vent en particulier affecter considérablement la durée  
de vie de la lampe.  
Affichage à cristaux liquides  
 Ne pas projeter la même image pendant une longue  
durée, car elle risquerait de former une après-image  
sur l'affichage à cristaux liquides.  
 L'affichage à cristaux liquides du projecteur a été fab-  
riqué en utilisant une technologie de haute précision  
afin d'offrir une image très détaillée. Il est possible  
que parfois quelques pixels figés apparaissent sur  
l'écran sous forme de points fixes bleus, verts ou  
rouges. Il est alors recommandé d'éteindre le project-  
eur puis de le rallumer environ 1 heure après. Bien  
noter que ceci n'affecte pas le bon fonctionnement de  
votre LCD.  
Composants optiques  
 Si vous utilisez la lampe 6 heures consécutivement  
chaque jour, les composants optiques pourraient  
nécessiter un remplacement dans moins d'un an.

Remplacement de l'unité de la lampe  
J Avant de remplacer le l'Unité de la lampe  
  Débrancher le cordon principal de la prise du secteur.  
  Vérifier que l'Unité de la lampe ainsi que les pièces autour aient eu le temps de refroidir.  
  Préparer un tournevis cruciforme.  
  Contacter un centre de service aprés-vente agréé pour acheter une Unité de la lampe (ET-LAB50) de  
rechange.  
  En cas d'installation du projecteur au plafond, ne jamais travailler directement dessous et éloigner le visage  
du projecteur.  
REMARQUE:  
• Avant de remplacer la lampe, la laisser refroidir pour éviter les risques de brûlures, les dommages et autres dangers.  
• Ne pas essayer de la remplacer par une lampe non autorisée.  
J Délai de remplacement de l'Unité de la 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.
