Projector features / Preparations
Projector features
This projector has a capability to project various picture signals onto a screen. 
This projector requires only a minimal amount of space for installation and can 
produce a large projected image from even a short distance.
This projector also can give a benefit to mobile users and others by offering a 
special function named “PC less presentation”.  Even without PC, this projector 
realizes the display on screen, getting JPEG, MPEG and Motion-JPEG pictures 
from USB storage media.
Preparations
Contents of package
Please see the “Contents of package” in the “User’s Manual (concise)” which 
is a book. Your projector should come with the items shown there. Contact 
immediately your dealer if anything is missing.
NOTE  • Keep the original packing materials, for future reshipment. Be sure 
to use the original packing materials when moving the projector. Use special 
caution for the lens.
Fastening the lens cover
To avoid losing the lens cover, please fasten the 
lens cover to the projector using the enclosed strap.
1. Fix the strap to the strap hole of the lens cover. 
Thread one end of the strap through the strap 
hole of the lens cover and make the loop at the end, 
and let the other end of the strap through the loop. 
Not have a knot in the strap at either end.
2. Fix the strap to the strap hole of the projector. 
Strap hole
Strap hole
Thread the other end of the strap through the strap hole of the projector and make 
the loop there. Let the lens cover with the one end of strap though the loop.
Replacing the filter cover for bottom-up use
For the projector installed bottom-up, please replace the filter cover with the 
enclosed filter cover for bottom-up use, to keep 
necessary ventilation space. 
Please refer to the “Air filter” (59) for how to 
detach and attach a filter cover.
WARNING  ►Consult with your dealer 
before a special installation such as 
suspending from a ceiling.

vents during use or just after use, since it is too hot.
►Do not look into the lens or vents while the lamp is on, since the strong light 
is not good for your eyes. 
►Do not handle the elevator knobs without holding the projector, since the 
projector may drop down.
CAUTION  ►Maintain normal ventilation to prevent the projector from heating 
up. Do not cover, block or plug up the vents. Do not place anything that can stick or 
be sucked to the vents, around the intake vents. Clean the air filter periodically.
►Do not use the security slot to prevent the projector from falling down, since it 
is not designed for it.
►Use the shutdown switch only when the projector is not turned off by normal 
procedure, since pushing this switch stops operation of the projector without 
cooling it down.
