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 flash and the projector pow\
er 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 p rocedure
q 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  28 before disconnecting the
plug from the wall outlet.
w Gently turn the projector
upside down.
NOTE:
• Place the projector on top of a soft
cloth so that it will not become
scratched.
e Remove the air filter.
Put your fingernails under the air
filter and pull the air filter out of
the projector. r
Clean the air filter.
Use a vacuum cleaner to clean
off any accumulated dust.
NOTE:
• Be careful not to let the air filter
get sucked into the vacuum
cleaner.
t Install the air filter.
NOTE:
• Be 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.
• 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 lamp unit
Warning
When replacing the lamp, allow it
to cool for at least one hour
before handling it.
•The lamp cover gets very hot, and
contact with it can cause burns.
Notes on replacing the
lamp unit
•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.
•After 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.
•A Phillips screwdriver is
necessary for removing the lamp
unit. Make sure that your hands
are not slippery when using the
screwdriver.
NOTE:
•The projector is not supplied with
a replacement lamp unit. Please
ask your dealer for details. Lamp
unit product no.: ET-LA730
CAUTION:
•Do not use any lamp unit other
than the one with the product
number indicated above.
Lamp unit replacementperiod
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 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:
•The usage hours explained above
are for use when the HIGH setting
has been selected for LAMP
POWER in the OPTION menu. If
the LOW setting is selected, the
brightness of the lamp will be less
and 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.

Lamp unit replacement p rocedure
NOTE:
•  If the lamp usage time has passed 2 000 hours (when LAMP POWER has
been set to  “HIGH ”), the projector will switch to standby mode after
approximately 10 minutes of operation. The steps  \b to  !\f on the next page
should thus be completed within 10 minutes.
q Turn off the MAIN POWER
switch according to the
procedure given in “Turning off
the power” on page  28, and
then disconnect the power
cord plug from the wall outlet
and check that the area around
the lamp unit has cooled down.
w Use a Phillips screwdriver to
turn the lamp unit cover fixing
screws at the bottom of the
projector, and then remove the
lamp unit cover from the
projector. e
Use a Phillips screwdriver to loosen
the two lamp unit fixing screws until
the screws turn freely. Then hold
the handle of the lamp unit and
gently pull it out from the projector.
r
Insert the new lamp unit while
making sure that the direction
of insertion is correct, and then
use a Phillips screwdriver to
securely tighten the lamp unit
fixing screws.
