B Be 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.
B 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.
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 power will
turn off. The air filter should be cleaned after every 100 hours of use.

Replacing the lamp unit
Warning
When replacing the lamp, allow it
to cool for at least one hour
before handling it.
B The lamp cover gets very hot,
and contact with it can cause
burns.
Notes on replacing the lamp
unit
B 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.
B Dispose of the removed old lamp
with the same care that would be
taken with a fluorescent light.
B A 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
when 2 000 hours of use have been
reached because of a much greater
chance of it exploding after this
time.
NOTE:
B 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.
B While 2 000 hours is the
intended replacement interval,
it is not a period of time
covered by warranty.
NOTE:
B If you need the lamp replacement, please purchase the lamp unit from
our customer service.
Lamp unit product no.: ET-LAE500
CAUTION:
B Do not use any lamp unit other than the one with the product number
