							Installation Methods
118
Installation Methods
The projector can be mounted on a ceiling or placed on a desk. Also, this 
projector can project images to various places because it can project 
images vertically or horizontally at each 90° angle.
Warning:
•A special method of installation is required when installing the projector to project 
images downward (ceiling mount) or upward. If it is not installed correctly, it could 
fall and turnover causing an accident and injury.
•If you use adhesives on the Ceiling mount fixing points 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.
•When mounting the projector on the ceiling, be sure to take measures to prevent it 
from falling such as passing a wire through the handles.Caution:•Do not install the projector in any positions other than those shown in the following 
illustrations, and do not install the projector at any angles other than those shown 
in the illustration on s p.119.
•Do not use the projector upside down.
•Set the Direction properly in the configuration menu according to the angle of 
installation. s p.73
•Using the projector at an improper angle or with the wrong configuration menu 
settings can cause malfunctions and shorten the operating life of optical parts.
An optional Ceiling mount is required when suspending the projector 
from a ceiling. sp.129The Projection setting can be changed from the configuration menu.

•Suspend the projector from the 
ceiling and project images from

							Cleaning
120
Cleaning
You should clean the projector if it becomes dirty or if the quality of 
projected images starts to deteriorate. 
Warning:
Do not use sprays containing a flammable gas to remove dirt or dust which is 
adhering to parts such as the lens or filter of the projector.
This could cause a fire due to the high temperature of lamps inside the unit.Cleaning the Projector's Surface
Clean the projector's 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 projector's surface. 
Caution:
Do not use volatile substances such as wax, alcohol, or thinner to clean the projector's 
surface. The quality of the case may change or become discolored.Cleaning the Lens
Use a commercially available cloth for cleaning glasses to gently wipe the 
lens.
Caution:
Do not rub the lens with harsh materials or subject the lens to shocks, as it can easily 
become damaged.
Cleaning the Air filter
Clean the air filter and the air intake vent when the following message is 
displayed or the Filter indicator is flashing green.
"Time to clean the air filter."
"Clean or replace the air filter."
Caution:
•If 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. Clean the air filter 
immediately when the message is displayed.
•Do not rinse the air filter in water. Do not use detergents or solvents.
•When using a brush for cleaning, use one with long soft bristles, and brush it lightly. 
If it is brushed too strongly, dust will be ground into the air filter and cannot be 
removed.
ProcedureA
Press the [
t
] power button on the remote control or the
