Important Operating Considerations
Do not place the projector on a tablecloth or other soft covering that may 
block the vents. Vents are placed along the back, left and front sides of the 
projector.
 Do not use a non-approved ceiling mount. In the unlikely event of 
the lamp rupturing, discard any edible items placed in the surrounding area 
and thoroughly clean the area along the sides and in the front of the projec-
tor.

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 35. We recom-
mends using an authorized ceiling mount. The Ceiling Mount Kit is 
sold separately; see the Accessories catalog that came with this projec-
tor or 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 43.
 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 100% at a 10:0 ratio when the projector is in 
4:3 mode (default mode). This means that if you have an image 10’ 
high, all 10’ will appear above the center of the lens. 
 This 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 43.

Connecting a computerRequired computer connectionsConnect one end of the VESA computer cable to the Computer 2 connector 
on the projector. Connect the other end to the video port on your computer. 
If you are using a desktop computer, you first need to disconnect the moni-
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.
NOTE: Always use the power cable that shipped with the projector. Optional computer connectionsTo control your computer ’s mouse using the projector ’s remote control, con-
nect the USB and DVI cables to the USB and DVI ports on your computer, 
and connect the other end to the Computer 1 (M1-D) connector on the pro-
jector. USB drivers must be installed to use the USB feature. For more infor-
mation, see page 12.
If your projector cannot receive the remote’s signal due to IR interference, 
you can connect directly to the projector via a remote cable. To do so, plug 
the remote cable into the wired remote connector on the projector. Plug the 
other end into the connector on the remote,
.
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.

If you are using a desktop computer and want to see the image on your 
computer screen as well as on the projection screen, plug the monitor cable 
to the Monitor out connector on the projector. 
You can also connect to your computer using a BNC cable. Connect the BNC 
connectors on the BNC cable to the appropriate Computer 3 connectors on 
the projector. Connect the other end to the video port on your computer. If 
you are using a desktop computer, you first need to disconnect the monitor 
cable from the computer ’s video port. When all 5 BNCs are connected, the 
projector handles separate synchs on H and V. 
You can control the projector from an LCD control panel, touch screen, or 
other control device or computer by connecting an RS-232 cable to the pro-
jector ’s Serial connector. Specific RS-232 commands can be found in the Ser-
vice and Support section of our website and in this User ’s Guide’s 
Appendix.
The projector can be managed by ProjectorNet networking software 
through its Network (RJ-45) connector. Contact an authorized dealer or 
visit our website for information on ProjectorNet.
