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 guide for proper startup and shutdown procedures.

• This product has a lamp which contains a very small amount of mer­cury. 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 side 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.

Connector Panel

The projector provides the following connection options:

• M1-DA/DVI (Digital Visual Interface)

• HDMI™ (High Definition Multimedia Interface)

• Component (RCA)

• SCART RGB (you must enable this connector, see page 26)

•S-video

• Composite video (RCA)

See “Video connectors” on page 7 for details.
The projector also provides the following connectors:

• RS-232 for serial control (not included on the IN72)

• 12 volt DC output (see below)





12 volt DC output

The 3.5mm mini-jack trigger provides a 12 volt, 0.25 amp DC output. It pro­vides a constant output while the projector is on. It has numerous uses. For
example, 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.

Positioning the projector

To 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 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 projector 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 Mount 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 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 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 and IN76, the image offset is 115%.

Choosing the aspect ratio

Aspect ratio is the ratio of the image width to image height. HDTV and
most DVDs are 16:9, which is the default 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 the internal scaler so that any resolu­tion larger than the native projector resolution is cropped on the edges. Let­terbox 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 anamorphic movies or HDTV, but you also have the
option of using 4:3, Native, or Natural Wide for 4:3 content. Keep in mind
that anamorphic movies only appear correctly if the DVD player is set to
output to a 16:9 television. Natural Wide stretches a 4:3 image to fill the
entire 16:9 screen. The center two-thirds of the image is unchanged; the
edges of the image are stretched.

Video connectors

The first step for connecting video is determining what type of output con­nectors your video device has. If there is more than one output, select the
one with the highest quality. The 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.

Connecting a video device

You can connect video devices such as VCRs, DVD players, camcorders,
digital cameras, video game consoles, HDTV receivers, and TV tuners to the
projector. Connect the audio from your video device to your stereo system
to get sound.

You can connect the projector to most video devices that can output video.
You cannot directly connect the coaxial cable that enters your house from a
cable or satellite company, the signal must pass through a tuner first. Exam­ples of tuners are digital cable boxes, VCRs, digital video recorders, and sat­ellite TV boxes. Basically, any device that can change channels is considered
a tuner.

A composite video cable is provided with your projector so you can quickly
and easily connect a video source to the projector and see the amazing
image that is displayed. Once you have determined a more permanent loca­tion for your projector, we recommend purchasing higher quality cables in
the proper length to get the best image from your particular video equip­ment. High quality cables optimized for your projector can be purchased
from www.infocus.com/store (in select areas) or from your dealer or
retailer.

Component (RCA) connection

If your device uses component connectors, plug a component video cable with red, green, and blue RCA connectors into the source device’s compo­nent connectors and the Component connectors on the projector.

SCART RGB connection

SCART (from Syndicat des Constructeurs d'Appareils Radiorécepteurs et
Téléviseurs) is a French-originated standard and connector for connecting
audio and video equipment to display devices. The video signal is sepa­rated into its primary components for brighter, more accurate colors and
sharper detail. You must enable this connector in the Source Enable menu to
use it, see page 26. You will also need a SCART to 4-RCA adapter to connect
to your SCART device.

Composite (RCA) video connection

Plug the composite video cable’s yellow connector into the video-out con­nector on the video device. Plug the other yellow connector into the yellow

Composite connector on the projector.

S-video connection

If your video device uses a round, four-prong S-video connector, plug the 
S-video cable into the S-video connector on your video device and into the

S-video connector on the projector.
