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 every 100 hours of use,
depending on the location where the projector is being used.
Cleaning procedure

switch and disconnect the
power cord plug from the
mains socket.
Turn off the MAIN POWER switch
according to the procedure given
in “Turning off the power” on
page
31 before disconnecting the
plug from the mains socket.
$ Gently turn the projector
upside down.
NOTE:
B Place the projector on top of a
soft cloth so that it will not
become scratched.
% Remove the air filter.

filter and pull the air filter out of
the projector.
& Clean the air filter.

off any accumulated dust.

get sucked into the vacuum
cleaner.
' Install the air filter.
NOTE:
B Be sure to install the air filter
cover before using the projector.

drawn into the projector, and

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.
