Important Operating Considerations for Safety
 Place the projector in a horizontal position no greater than 8 degrees off 
axis.
 Locate the projector in a well-ventilated area without any obstructions 
to intake or exhaust vents. Do not place the projector on a tablecloth or 
other soft covering that may block the vents. 
 Locate the projector at least 4 (1.2 m) away from any heating or cooling 
vents.
 Use only approved ceiling mounts.
 Use only the power cord provided. A surge-protected power strip is 
recommended.
 Refer to this manual for proper startup and shutdown procedures.
 This product has a lamp which contains a very small amount of mer-
cury. Wash hands after cleaning the area and handling the ruptured 
lamp. Dispose of it as required by local, state or federal ordinances and 
regulations. For more information see www.eiae.org.
 In the unlikely event of a lamp rupture, particles may exit through the 
projector vents. When the projector is turned on, keep people, food, 
and drinks out of the keep out area under and around the projector, as 
indicated by the X areas below.Follow these instructions to help ensure image quality and lamp life over 
the life of the projector. Failure to follow these instructions may affect the 
warranty. For complete details of the warranty, see the Warranty booklet.

Positioning the projectorTo determine where to position the projector, consider the size and shape of 
your screen, the location of your power outlets, and the distance between 
the projector and the rest of your equipment. Here are some general guide-
lines:
 Position the projector on a flat surface at a right angle to the screen. The 
projector (with the standard lens) must be at least 3 feet (0.9m) from the 
projection screen.
 Position the projector within 10 feet (3m) of your power source and 
within 6 feet (1.8m) of your video device (unless you purchase exten-
sion cables). To ensure adequate cable access, do not place the projector 
within 6 inches (.15m) of a wall or other object.
 If you are installing the projector on the ceiling, refer to the installation 
guide that comes with the Ceiling Mount Kit for more information. To 
turn the image upside down, see “Ceiling” on page 29. We recom-
mends using an authorized ceiling mount. The Ceiling Mount Kit is 
sold separately; visit our website for more information.
 Position the projector the desired distance from the screen. The distance 
from the lens of the projector to the screen, the zoom setting, and the 
video format determine the size of the projected image. For information 
about image sizes at different distances, see “Projected image size” on 
page 37.
 For the standard lens that comes with the projector, the image exits at a 
given angle. However, the lens shift feature makes the image offset 
variable. The image offset is 90% at a 9:1 ratio when the projector is in 
4:3 mode (default mode). This means that if you have an image 10’ 
high, the bottom of the image will be 1’ below the center of the lens. 
 The image offset is 50% when the lens shift is at a 1:1 ratio. This means 
that if you have an image 10’ high, the bottom of the image will be 5’ 
below the center of the lens. 
 For information about the optional lenses image offsets, see “Projected 
image size” on page 37.

tor cable from the computer ’s video port. 
Connect the black power cable to the connector on the back of the projector 
and to your electrical outlet.

nect the optional M1-DA cable to the USB and DVI ports on your computer, 
and connect the other end to the Computer 1 (M1-DA) connector on the 
projector. 
To have sound with your presentation, connect the audio cable to your com-
puter and to the corresponding computer Audio In connector on the projec-
tor.

other control device or computer by connecting an RS-232 cable to the pro-
jector ’s Serial Control connector. Specific RS-232 commands can be found 
in the Service and Support section of our website and in the Appendix.

tion to learn your computer ’s key combination.
