Installation Precautions  
Provide proper ventilation for this projector.  
The projector is equipped with ventilation holes(intake) on  
the bottom and ventilation holes(exhaust) on the front. Do  
not block or place anything near these holes. Internal heat  
build-up may occur, causing picture degradation or dam-  
age to the projector.  
Do not place the projector on a carpet, rug or other similar  
surface. It may prevent a adequate ventilation of the pro-  
jector bottom. This product should be mounted to a wall  
or ceiling only.  
Never push projector or spill any kind of liquid into the  
projector.  
Leave an adequate distance (30 cm or more) around the  
projector.  
Place this projector in adequate temperature and humidity conditions.  
Install this projector only in a location where adequate temperature and humidity is available. (Refer to page 35)  
Don’t place the projector where it can be covered with dust.  
This may cause overheating of the projector.  
Do not obstruct the slots and openings of the projector. This may cause overheating and create a fire hazard.  
This projector is manufactured using high-precision technology. You may, however, see tiny black points and/or bright  
points (red, blue or green) that continuously appear on the projector Screen. This is a normal result of the manufacturing  
process and does not indicate a malfunction.  
To display DTV programs, it is necessary to purchase a DTV receiver (Set-top Box) and connect it to the projector.  
The remote control may not work when a lamp equipped with electronic ballast or a three-wavelength lamp is installed.  
Replace those lamps with international standard products to use the remote control normally.  
13  
Installing and Composition  
Positioning the Projector  
1. Place the projector on a sturdy and horizontal surface.  
2. Place the projector the desired distance from the screen. The distance between the projector and the screen  
determines the actual size of the image.  
3. Position the projector so that the lens is set at a right angle to the screen. If the projector is not set at a right  
angle, the screen image will be crooked. Although, slight angles can be counteracted using the Keystone  
adjustement. (Refer to page 25.).  
4. Connect the power cable to the projector and the wall outlet after placing the projector in its desired loca-  
tion.
