If you are experienced in setting up projection systems, use the Quick Setup 
card that is included with the projector. For complete details on connecting 
and operating the projector, refer to this User ’s Guide. Electronic versions of 
this User ’s Guide in multiple languages are available on our website.

culator, laptop activation commands, connector pin outs, a glossary, the 
product data sheet), a web store to buy accessories, and a page for online

Important Operating Considerations for Safety
 Place the projector in a horizontal position no greater than 15 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 InFocus-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.
 In the unlikely event of the lamp rupturing, discard any edible items 
placed in the surrounding area and thoroughly clean the area along all 
sides of the projector. Wash hands after cleaning the area and handling 
the ruptured lamp. This product has a lamp which contains a very 
small amount of mercury. Dispose of it as required by local, state or 
federal ordinances and regulations. For more information see 
www.eiae.org.
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 section at 
the end of this Users Guide.

							5 Connector Panel
The projector provides both computer and video connection options, 
including: 
 DVI (M1-DA)
 Component SD/ED/HD (RCA)
 S-video
 Composite audio/video (RCA)
The projector also provides the following connectors:
 Audio out
 12 volt DC output (see below)12 volt DC outputThe 3.5mm mini-jack trigger provides a 12 volt DC output. It provides a 
constant output while the projector is on. It has numerous uses. For exam-
ple, if you connect your projection screen to the 12 volt DC output with the 
cable that came with your screen, when you turn on the projector the screen 
will move down; when you turn the projector off, the screen will return to 
the storage position. To use the 12 volt DC output, you must first remove 
the safety plug and turn Screen Trigger on in the System menu (see 
page 38).

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 must be at least 4.9 feet (1.49m) 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 38. We recommend 
using an authorized ceiling mount.
 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. The top illus-
tration to the right shows three projected image sizes. For more infor-
mation about image sizes at different distances, see “Projected Image 
Size” on page 43.
 The image offset is 127.3% when the projector is in 16:9 mode. This 
means that if you have an image 10’ high, the bottom of the image will 
be 2.73’ above the center of the lens. 
 See “Connecting a video device” on page 15 for additional information 
on 16:9 mode.

Projector and Device Connector GuideThe following illustration and table should help you find the connectors to use and obtain the best resolution possible from your input devices, such as com-
puters, standard VCRs, DVD players (progressive and interlaced), HDTV sources, TV and satellite tuners, camcorders, video games (progressive and inter-
laced), and laser disc players.Computer connectionsComputer connections involve attaching the VGA and USB ends of the provided computer cable to a computer and connecting the other end (M1 cable end) 
to the M1-DA input on the projector. The USB part of the computer cable allows you to advance slides in a PowerPoint™ presentation via an optional remote 
control. See page 10 for computer/projector setup information.Video connectionsThe first step for connecting video is deciding what type of output connector you want to connect to the projector. If there is more than one output, select the 
one with the highest quality. The best quality ranking, with 1 being the highest and 3 being the lowest, is:1
