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-venti lated area without any obstructions 
to intake or exhaust vents. Do not pl ace 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 guide for proper  startup and shutdown procedures.Wa r n i n g :  Hg – Lamp contains mercury. Manage in accordance 
with local disposal laws. See  www.lamprecycle.org. In the unlikely event of a lamp rupture, particles may exit through the 
projector side vents. When the projector is turned on, keep people, 
food, and drinks out of the keep ou t area under and around the pro
-
jector, 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 foll ow these instructions may affect the 
warranty. For complete details of th e 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 po wer outlets, and the distance between 
the projector and the rest of your eq uipment. Here are some guidelines: Position the projector on a flat surface at a right angle to the screen. The 
projector must be at least 4.9 feet  (1.5m) from the projection screen. For safety reasons, position the proj ector within 10 feet (3m) of your 
power source (running  extension cables may introduce a trip hazard). 
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 Mou nt Kit for more information. To 
turn the image upside down, see “Ceiling” on 
page
 26. We recommend 
using an InFocus authorized ceiling mount.
 Position the projector the desired dist ance from the screen. The distance 
from the lens of the projector to th e screen, the zoom setting, and the 
video format determine the si ze of the projected image.  The image offset is 128% for the IN72. This means that if you have an 
image 10’ high, the bottom of the image  will be 2.8’ above the center of 
the lens. For the IN74/ IN76/IN78, the image offset is 115%.

Choosing the aspect ratioAspect ratio is the ratio of the image width to image height. HDTV and 
most DVDs are 16:9, which is the defa ult for this projector. When in 4:3 
mode the projector places black bars  on both sides of the image. Native 
mode centers the image and turns off th e internal scaler so that any resolu
-
tion larger than the native projector resolution is cropped on the edges. Let
-
terbox expands the image to fill the screen.What you plan to project will also help you choose between 4:3 and 16:9. For 
example, most TV shows are 4:3, while most movies are 16:9. If you have a 
16:9 screen, then you should select an  aspect ratio of 16:9 for anamorphic 
movies and HDTV, and Native for 4:3 content. If you have a 4:3 screen you 
should still use 16:9 for an amorphic movies or HDTV, but you also have the 
option of using 4:3, Native, or Natura l Wide for 4:3 content. Keep in mind 
that anamorphic movies on ly appear correctly if the DVD player is set to 
output to a 16:9 television. Natural Wi de stretches a 4:3 image to fill the 
entire 16:9 screen. The center two-thir ds of the image is unchanged; the 
edges of the image are stretched.

Video connectorsThe first step for connecting video is determining what type of output con
-
nectors your video device has. If ther e is more than one output, select the 
one with the highest quality. Th e best quality ranking, with 1 being the 
highest, is:1
M1-DA/DVI or HDMI (both are digital inputs)
2
component /SCART RGB video (RCAs)
3
S-video 
4
composite video (RCA)
If your device has a VGA connector,  you can use the M1-DA/DVI connector 
for a high quality image. Many PC  game systems have VGA connectors.

-
nectors are digital and yield the highest quality image. It is common for 
these signals to be encrypted with HDCP (high-bandwidth digital-content 
protection). Your new projector ships standard with decryption codes so 
you can enjoy these high quality, all digital images. This projector uses the M1-DA conne ctor, which has the following advan

ing they have vertical scanning line s of 720 progressive, 1080 interlaced or 
higher. The IN72 and IN74 are EDTV  (Enhanced Definition Television) 
monitors, meaning they ha ve vertical scanning lines of 480 progressive or 
higher. HD content can be displayed on  an EDTV monitor, the resolution is 
just less than that of an HDTV.DVI connectionIf your video device uses a DVI conne ctor, plug the DVI end of an M1-DA 
cable into the video-out connector on  the video device. This connector may 
be labeled “To Monitor” on the video device. Plug the M1-DA end of the 
cable into the  M1-DA/DVI connector on the projector. 
HDMI connectionHDMI is a standard, uncompressed,  all-digital audio/video interface. 
HDMI provides an interface between sources, such as set-top boxes, DVD 
players, and receivers and your proj ector. Plug an HDMI cable into the 
video-out connector on the  video device and into the HDMI connector on 
the projector.An M1-DA to HDMI adapter is included  with the IN78. This plugs inot the 
M1-DA connecotr and allows a second HDMI source to be connected. Note:
