Be sure to disconnect the power
cord by following the procedure
given on page 24.
$ Gently turn the projector
upside down, and then remove
the air filter cover.
NOTE:
B 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.
B Do not use detergent when
washing the air filter.
B If the dust cannot be removed

being replaced, replace the air

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.
