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
before using the projector. If
the projector is used without
the air filter installed, dust and
other foreign particles will be
drawn into the projector, and
malfunctions will result. Air filter cover

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 contact with 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 “OPTION2”
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.
BWhile 2 000 hours is the
intended replacement interval,
it is not a period of time
covered by warranty.

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.
