As shown in the figures below, this unit can be placed in four different styles.
The factory setting is “Front” and “Standard.” Set “Projection mode 1” and “Projection mode 2” in the
“Default setting” menu (see
p.35) in accordance with your needs.
Determine the projection distance and place the unit.
Determine the projection distance from the lens to the screen to obtain the desired screen size. (The
screen sizes listed below are approximate values for a full-size image projected with no keystone
adjustment.)
The screen size decreases as the lens comes closer to the screen; it increases as the lens goes away
from the screen.

• Always obey the instructions listed in IMPORTANT SAFETY INSTRUCTIONS when placing the unit.
• If you wish to mount the projector on the ceiling, be sure to ask your dealer to do so. Mounting the projector
on a ceiling requires special ceiling brackets (sold separately) and specialized knowledge. Improper
mounting could cause the projector to fall, resulting in an accident.
• If you wish to mount the projector on the ceiling, remove the tilt stand attached to this unit. Mounting the
projector with the tilt stand on the ceiling could cause it to fall, resulting in an accident.
• If the projector is ceiling-mounted, install the breaker for turning off the power in case of emergency. Let
everyone involved with the use of the projector know that fact.
