to appear fuzzy. Set the projector up in the room about one hour before it is used. If condensation forms on 
the lens, turn the projector off and wait for the condensation to disappear.

Installation MethodsThe projector supports the following four different projection methods.     
 Wa r ning
 A special method of installation is required when suspending the 
projector from a ceiling (ceiling mount). If it is not installed 
correctly, it could fall causing an accident and injury.
 If you use adhesives on the ceiling mount to prevent the screws 
from loosening, or if you use things such as lubricants or oils on 
the projector, the projector case may crack causing it to fall from 
its ceiling mount. This could cause serious injury to anyone under 
the ceiling mount and could damage the projector. 
When installing or adjusting the ceiling mount, do not use 
adhesives to prevent the screws from loosening and do not use oils 
or lubricants and so on. AttentionDo not use the projector on its side. This may cause malfunctions to 
occur. 
 Project images from in front 
of the screen. 
(Front projection) Project images from behind a 
translucent screen.
(Rear projection)
 Suspend the projector from 
the ceiling and project images 
from in front of the screen. 
(Front/Ceiling projection) Suspend the projector from 
the ceiling and project images 
from behind a translucent 
screen. 
(Rear/Ceiling projection)q
 An optional ceiling mount is required when suspending 
the projector from a ceiling. s
p.64
 You can change the setting as follows by pressing down the 
[A/V Mute] button on the remote control for about five 
seconds.

CleaningYou should clean the projector if it becomes dirty or if the quality of 
projected images starts to deteriorate. Cleaning the Projectors Surface
Clean the projectors surface by wiping it gently with a soft cloth. 
If the projector is particularly dirty, moisten the cloth with water 
containing a small amount of neutral detergent, and then firmly wring the 
cloth dry before using it to wipe the projectors surface. 
Cleaning the Lens
Use a commercially available cloth for cleaning glasses to gently wipe the 
lens. 
Cleaning the Air Filter and Air Intake Vent
Clean the air filter and the air intake vent when the following message is 
displayed.
The projector is overheating. Make sure nothing is blocking the air vent, 
and clean or replace the air filter. sHow to replace the air filter p.56AttentionDo not use volatile substances such as wax, alcohol, or thinner to 
clean the projectors surface. The quality of the case may change or 
become discolored.AttentionDo not rub the lens with harsh materials or subject the lens to 
shocks, as it can easily become damaged.
AttentionIf dust collects on the air filter it can cause the internal temperature 
of the projector to rise, and this can lead to problems with operation 
and shorten the optical engines service life. Clean the air filter 
immediately when the message is displayed.q
 If a message is frequently displayed, even after cleaning, it 
is time to replace the air filter. Replace it with a new air 
filter. 
s
p.56
 It is recommended that you clean these parts at least once 
every three months. Clean them more often than this if 
using the projector in a particularly dusty environment.
