Cleaning the Projector
• Do not remove any covers or screws other than those explicitly mentioned in this manual. There
are high voltage components inside the machine, which can cause electric shock. Contact your
sales or service representative if any of the machine's internal components require maintenance,
adjustment, or repair.
• Do not disassemble or modify this machine. Doing so can result in fire and electric shock.
• Do not attempt to clean or replace parts for a machine that is installed in a high location on a
wall or ceiling. Doing so may cause it to fall down, resulting in an injury.
• Do not open the lamp cover of a machine that is installed on a wall or ceiling. Doing so may

• Contact your sales or service representative to clean or replace parts for a machine that is
installed on a wall or ceiling.
• When performing maintenance on the machine, disconnect the power cord from the wall outlet
for safety.
• An error in which the lamp turns off by itself during operation may occur if the air filter, the bottom
air intake vents, and the speaker vents get clogged and the interior of the projector overheats due
to inadequate circulation of air. Clean the air filter, the bottom air intake vents, and the speaker
vents also when "Temperature Error" is displayed.
Cleaning the Air Filter
The air filter prevents dust and dirt from entering the interior of the projector. If you will use the projector,
install the air filter.
• If an air filter is damaged, replace it with a new one. Using a damaged air filter may cause the
projector to stop operating or malfunction. For details, contact your sales representative or service
representative.
If the message "Check the air filter for dirt." is displayed, check the air filter for dirt or dust, and use the
following procedure to clean off any dirt or dust.
