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
#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 23 before disconnecting the
plug from the wall outlet.
$Gently turn the projector
upside down.
NOTE:
BPlace the projector on top of a
soft cloth so that it will not
become scratched.
%Remove the air filter.
Put your fingernails under the air
filter and pull the air filter out of
the projector.
&Clean the air filter.
Use a vacuum cleaner to clean
off any accumulated dust.
NOTE:
BBe careful not to let the air filter
get sucked into the vacuum
cleaner.
'Install the air filter.
NOTE:
BBe 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.
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.
