projected onto the screen when no
signal is being input to the projector.FRONT/REARThis setting should be changed in
accordance with the projector
setting-up method.
Set to “FRONT” when using a
normal reflective screen with the
projector positioned in front of the
screen, and set to “REAR” when
using a translucent screen with the
projector positioned behind the
screen.DESK/CEILINGThis setting should be changed in
accordance with the projector
setting-up method.
Set to “DESK” when setting up the
projector on a desk or similar, and
set to “CEILING” when suspendingthe projector from the ceiling using
the ceiling bracket which is sold
separately.
FAN CONTROLIf using of this projector at high
elevations (above 1400 m), set FAN 
CONTROL to “HIGH”.LAMP POWERThis setting changes the lamp
brightness. When set to “LOW”, the
luminance of the lamp is reduced, but
the projector uses less power, and
the operating noise is also reduced.
This can help to extend the lamp’s
operating life. If using the projector in
small rooms where high luminance is
not required, it is recommended that
you set the LAMP POWER to “LOW”.LAMP RUNTIMEThis setting displays the usage time
for the lamp unit which is currently
being used. 
NOTE:
BThe lamp’s operating life varies
depending on the usage conditions
(such as the LAMP POWER
setting and the number of times
the power is turned on and off).

46IndicatorsThere are two indicators on the control panel of the projector which give
information about the operating condition of the projector. These indicators
illuminate or flash to warn you about problems that have occurred inside the
projector, so if you notice that one of the indicators is on, turn off the power
and check the table below for the cause of the problem.ProblemIndicator

between 20% and 80% (with no condensation). [If you set the
FAN CONTROL to “HIGH” (page 41), set up the projector in a
place where the temperature is between 0 °C (32 °F) and 35 °C
(95 °F) and the humidity is between 20% and 80% (with no

Replacing the lamp unitWarningWhen replacing the lamp, allow it
to cool for at least one hour
before handling it.
BThe lamp cover gets very hot,
and contact with it can cause
burns.Notes on replacing the
lamp unitBThe 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.
BAfter 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.
BA Phillips screwdriver is
necessary for removing the lamp
unit. Make sure that your hands
are not slippery when using the
screwdriver.
NOTE:
BThe projector is not supplied with
a replacement lamp unit. Please
ask your dealer for details. Lamp
unit product no.: ET-LA730
CAUTION:
BDo not use any lamp unit other
than the one with the product
number indicated above.
Lamp unit replacement
periodThe 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 lamps
characteristics, usage conditions
and the installation environment.
Early preparation for lamp
replacement is encouraged.
A lamp that has exceeded 2 000
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 2 000 hours of use have
been reached.
NOTE:
BThe usage hours explained
above are for use when the HIGH
setting has been selected for
LAMP POWER in the OPTION2
menu. If the LOW setting is
selected, the brightness of the
lamp will be less and life of the
lamp can be extended.
BWhile 2 000 hours is the intended
replacement interval, it is not a
period of time covered by
warranty.
Cleaning and replacing the air filterIf 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.Cleaning procedure#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 27 before disconnecting the
plug from the wall outlet.
$Gently turn the projector
upside down.
NOTE:
BPlace 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.
NOTE:
BBe careful not to let the air filter
get sucked into the vacuum
cleaner.
'Install the air filter.
NOTE:
BBe 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.
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.

ATTENTION:Cet appareil est équipé d’une fiche
de courant à trois broches avec
mise à la terre. Ne pas retirer la
broche de mise à la masse de la
fiche. 
Cette fiche ne pourra être utilisée que dans une prise avec
mise à la terre. Ceci est une précaution sécuritaire. S’il est
impossible d’insérer la fiche dans la prise, s’adresser à un
électricien. Ne pas annuler la protection de la fiche à mise à
la terre.Ne pas retirerNOTES IMPORTANTES
CONCERNANT LA SÉCURITÉ
Le symbole de la flèche en forme d’éclair, dans un triangle,
avertit l’usager de la présence de “tensions dangereuses” à
l’intérieur du produit qui peuvent être de force suffisante pour
constituer un risque de choc électrique aux personnes.
Le point d’exclamation dans un triangle avertit l’usager de la
présence d’instructions importantes concernant l’utilisation et
l’entretien (réparation) dans la littérature accompagnant le
produit. Alimentation:Ce projecteur LCD est conçu pour fonctionner sur secteur
de 100 V - 240 V, 50 Hz/60 Hz seulement.
ATTENTION:Le cordon d’alimentation secteur fourni avec le projecteur
peut être utilisé uniquement pour une alimentation électrique
de 125 V, 10 A maximum. Si on veut l’utiliser avec une
tension ou un courant plus forts, on doit se procurer un autre
cordon d’alimentation de 250 V. Si on utilise le cordon fourni
sous ces conditions, risque de provoquer un incendie. AVERTISSEMENT:
POUR REDUIRE LES RISQUES DE FEU OU DE CHOC
ÉLECTRIQUE, NE PAS EXPOSER CE PRODUIT À L’EAU
OU À L’HUMIDITÉ
Précautions de sécuritéAVERTISSEMENTEn cas de problème (pas d’image ou de son), ou si le projecteur dégage
de la fumée ou une odeur étrange, éteindre l’appareil et débrancher
immédiatement la fiche d’alimentation de la prise de courant.
BNe pas continuer d’utiliser le projecteur dans ces cas, autrement cela peut
entraîner un incendie ou des chocs électriques.
BAprès s’être assuré que de la fumée ne se dégage plus, s’adresser à un
centre technique agréé et demander que les réparations nécessaires
soient faites.
BLe fait de réparer le projecteur soi-même est très dangereux, et ne doit
jamais être fait.
Ne pas installer ce projecteur dans un endroit qui n’est pas assez
résistant pour supporter le poids du projecteur.
BSi l’emplacement d’installation n’est pas assez résistant, le projecteur
risque de tomber et causer de graves blessures et (ou) des dommages.
Demander à un technicien qualifié d’installer le projecteur par exemple
s’il est installé au plafond.
BSi l’installation n’est pas faite correctement, cela peut entraîner des
blessures ou des chocs électriques.
Si de l’eau ou des objets étrangers entrent dans le projecteur, si le
projecteur tombe, ou si le boîtier est endommagé, éteindre l’appareil et
débrancher immédiatement la fiche d’alimentation de la prise de
courant.
BSi l’on continue d’utiliser le projecteur dans cette condition, cela peut
entraîner un incendie ou des chocs électriques.
BS’adresser à un centre technique agréé pour que les réparations
nécessaires puissent être faites.
Ne pas surcharger la prise de courant.
BSi l’alimentation est surchargée (par exemple, par l’utilisation de trop
d’adaptateurs), cela risque de faire surchauffer le projecteur et peut
entraîner un incendie.
Ne pas retirer le capot ou le modifier.
BDes hautes tensions qui peuvent causer de graves blessures sont
présentes à l’intérieur du projecteur.
BPour toute inspection, réglage ou réparation, s’adresser à un centre
technique agréé.
