projector, causing deterioration in the projector quality 
and fire.
Do not use flammable solvents (benzene, thinner, 
etc.) and flammable aerosols near the projector.
Flammable substances may ignite causing fire or 
breakdown because the temperature inside the 
projector rises very high while the lamp is illuminating.
Do not use the projector with condensation on it. 
It can lead to breakdown or other failure. 
Place of installation
For safety’s sake, refrain from setting the projector 
at any place subjected to high temperature and high 
humidity. Please maintain an operating temperature, 
humidity, and altitude as specified below.
Operating temperature: between +41°F (+5°C) and 
•	
+95°F (+35°C)
Operating humidity: between 30% and 90%
•	
Never put any heat-producing device under the 
•	
projector so that the projector does not overheat.
Do not attach the projector to a place that is 
•	
unstable or subjected to vibration.
Do not install the projector near any equipment that 
•	
produces a strong magnetic field. Also refrain from 
installing near the projector any cable carrying a 
large current.
Place the projector on a solid, vibration free surface;

Vertical directions When operating the remote control, keep the distance 
from the remote control to the projector via the screen 
within about 5 m (15 feet). The operable range of the 
remote control, however, depends on the characteristics 
of the screen.
Operate the remote control

Setting up your projector
Setting up the screen
Install the screen perpendicularly to the projector. If the screen can not be installed in such a way, adjust the 
projection angle of the projector. (See page 12.)Install the screen and projector so that the projector’s lens is placed at the same height and horizontal position of 
•	
the screen center.
Do not install the screen where it is exposed to direct sunlight or lighting. Light directly reflecting on the screen 
•	
makes the projected images washed-out and hard to view.
SCREEN SIZE
You can keep the image display area within the screen by setting SCREEN SIZE in the ADVANCED MENU of IMAGE 
menu according to the aspect ratio of the actual screen. Select 16:9 when the aspect ratio of the screen is 16:9 or 
4:3, and select CINEMA SCOPE (2.35:1) when the aspect ratio is 2.35:1 \
(CinemaScope).
When setting SCREEN SIZE to CINEMA SCOPE (2.35:1):CinemaScope size movies are projected in the full screen. 
•	
Set ASPECT in the FEATURE menu to 16:9 when displaying Vista-size images. In this case, they \
are squeezed 
•	
horizontally.
When ASPECT in the FEATURE menu is set to AUTO and 480i/p, 576i/p, 720p, or 1080i/p signal is \
input, the part 
•	
for displaying subtitles is not projected. To display subtitles, reset SCREEN SIZE to 16:9 and adjust the image 
position using VERTICAL LOCATION in the ADVANCED MENU of the IMAGE menu. (To display the menu on the 
screen, adjust SHUTTER(U) in the SIGNAL - USER menu to position the menu.\
)
