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%.
NOTE: Visit the Service section of our website at www.infocus.com/calculator for an interactive image size calculator.

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.
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.
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.
9
Digital connections
The M1-DA/DVI and HDMI (High-Definition Multimedia Interface) connectors 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 connector, which has the following advantages:
• allows connection to a digital DVI source
• allows connection to a component source
• allows connection to an analog computer source
• carries a USB control signal which allows you to easily update your
projector’s software as enhancements become available.
• has output pins that can power accessories.
The IN76 is an HDTV (High Definition Television) monitor, meaning it has
vertical scanning lines of 720 progressive, 1080 interlaced or higher. The
IN72 and IN74 are EDTV (Enhanced Definition Television) monitors, meaning they have 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 connection
If your video device uses a DVI connector, 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 connection
HDMI 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 projector. Plug an HDMI cable into the
video-out connector on the video device and into the HDMI connector on
the projector.
Note that the projector has no audio capabilities, so audio signals transferred through HDMI will not be audible.
Computer connections
You can connect a computer’s VGA connector to the M1-DA/DVI input on
the projector using an M1-A cable.
RS-232 connections (IN74 and IN76 only)
You can control the projector from an LCD control panel or computer by
connecting an RS-232 cable to the projector’s Serial control connector. Specific RS-232 commands can be found in the Service section of our website at
www.infocus.com/support.

in the Presets menu, then choose Save User 1, 2, or 3. You can recall these
settings in the future by selecting the appropriate user presets. All settings
in the Picture menu (except Keystone) are saved and recalled.
Gamma: Gamma tables contain preset intensity configurations optimized
for the input source. You can select a gamma table that has been specifically
tuned for either film, CRT (Cathode Ray Tube), video, PC, or Bright Room
input. (Film input is material originally captured on a film camera, like a
movie; video input is material originally captured on a video camera, like a
TV show or sporting event.) White Peaking increases the brightness of
whites that are near 100%.
NOTE: Your viewing preferences may vary. Cycle through the gamma
options and pick the one you like the best.

Remember that not all options in the menus are available for all sources/
signals.
Phase: adjusts the horizontal phase of a computer source.
Tr a ck i n g : adjusts the vertical scan of a computer source.
Horizontal/Vertical Position: adjusts the position of a computer source.
Sync Threshold Adjust: (progressive signals only) If a hardware device,
such as a DVD player, is not syncing properly with the projector, adjust this
option to help it to sync when connected to the projector.
Flesh Tone Correction: this modifies colors to make the skin complexion
better.
Film Mode: controls deinterlacing and is On by default. When checked, it
assumes the incoming signal is film material and optimizes the image
accordingly.
Sharpness: (video sources only) changes the clarity of the edges of a video
image. Select a sharpness setting.
Color Space: This option applies to computer and component video
sources. It allows you to select a color space that has been specifically tuned
for the input signal. When Auto is selected, the projector automatically
determines the standard. To choose a different setting, turn off Auto, then
choose RGB for computer sources, choose either REC709 or REC601 for
component video sources.

Color Temperature: changes the intensity of the colors. Select a value.
Native means an uncorrected/unchanged color temperature. Other values
change the white point of the colors. 6500K is generally used for film content and 9300K is used for TV video.
Color Control: allows you to individually adjust the gain and offset of the
red, green, and blue colors. These advanced controls have the same effect as
contrast and brightness, but each controls a single color only.
Video Standard: when it is set to Auto, the projector attempts to automatically pick the video standard based on the input signal it receives. (The
video standard options may vary depending on your region of the world.) If
the projector is unable to detect the correct standard, the colors may not
look right or the image may appear “torn.” If this happens, manually select
a video standard by selecting NTSC, PAL, or SECAM from the Video Standard menu.
Overscan: removes noise around the edges of the video image. Select Zoom
to remove the outer 3% of the image and scale the image back up to its original size. Select Crop to remove the outer 3% of the image without rescaling
the image.
Noise Reduction: adjusts signal noise reduction. Choose Enable then adjust
the level. The software determines the differences between successive image
frames and averages the changes out to reduce the noise.

Settings menu
Sources: allows programming of source buttons, enables autosource, and
enables the SCART RGB source. When Autosource is selected, the Source
Enable feature indicates which sources the projector attempts to lock onto.
You can use the Source Enable feature to eliminate certain sources from this
search, which will speed the search. By default, the check boxes for all
sources are checked except SCART RGB. Uncheck a source box to eliminate
it from the search. When Autosource is not checked, the projector defaults
to Component initially, then defaults to whatever the last active source was
when the projector was powered down. To display another source, you
must manually select one by pressing the Source button on the remote or
keypad. This cycles through all the sources that are selected in the Source
Enable menu.
The Source 1, 2, and 3 menus in the Sources menu allow you to assign a
source to the Source 1, 2, and 3 buttons on the remote. The Source 4 menu
selection would apply to the Custom key if that option is chosen in the Custom key menu, see page 27.
To use the SCART RGB source, you must first select it in the Source Enable
menu (the projector cannot automatically detect this source). Enabling
SCART will disable Component and Composite sources.
System>Rear: reverses the image so you can project from behind a translucent screen. Ceiling: turns the image upside down for ceiling-mounted projection. Auto Ceiling: uses an internal sensor to automatically turn on
ceiling mount mode if the projector is inverted. High Power: maximizes the
light output of the lamp. Auto Power: When Auto Power is checked, the
projector automatically goes into the startup state after the projector
receives power. This allows control of ceiling mounted projectors with a
wall power switch Display Messages: displays status messages (such as
“Searching”) in the lower-left corner of the screen.Tr a ns lu c en t O S D: makes
the menus translucent. This prevents the image from being completely cov
ered by the menus while you are making image adjustments. Sleep Timer:
automatically turns off the projector after 4 hours. Powe r S ave: automatically turns the lamp off after no signals are detected for 20 minutes. After 10
additional minutes with no signal, the projector powers down. If an active
signal is received before the projector powers down, the image is displayed.

Maintenance
Cleaning the lens
1 Apply a non-abrasive camera lens cleaner to a soft, dry cloth.
• Avoid using an excessive amount of cleaner, and don’t apply the
cleaner directly to the lens. Abrasive cleaners, solvents or other harsh
chemicals might scratch the lens.
2 Lightly wipe the cleaning cloth over the lens in a circular motion.
Replacing the projection lamp
The lamp hours timer in the Service Info menu counts the number of hours
the lamp has been in use. Twenty hours before the lamp life expires, a message appears on the screen at startup indicating that you should change the
lamp. The LED on top of the projector also blinks red twice to indicate that
the lamp should be changed.
NOTE: You can order new lamp housings from www.infocus.com (in select
areas), your retailer or your dealer. Use only a replacement lamp with the
same type and rating as the original lamp.
1 Turn off the projector and unplug the power cord. If ceiling mounted,
disconnect all cables and detach the projector from the ceiling mount.
2 Wait 60 minutes to allow the projector to cool thoroughly.
3 Turn the projector upside down on a soft cloth so that the lamp door is
facing you. Remove the base or ceiling mount plate, if attached, by
removing the 3 screws.

Push the 2 tabs on the lamp door toward the front of the projector and
lift the lamp door off.
5 Loosen the two captive screws that attach the lamp housing to the pro-
jector.
6 Detach the lamp connector from the projector by depressing the locking
tab on the connector and lightly pulling it free.
WARN IN G:
To avoid burns, allow the projector to cool for at least 60 minutes
before you replace the lamp.
Be extremely careful when removing the lamp housing. In the
unlikely event that the bulb ruptures, small glass fragments may be
generated. The lamp housing is designed to contain these fragments, but use caution when removing the lamp housing. Before
replacing the lamp, clean the lamp compartment and dispose of
cleaning materials. Wash hands after lamp replacement. 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.
7 Carefully remove the lamp housing. Dispose of the lamp in an environ-
mentally proper manner.
8 Install the new lamp housing and tighten the screws.
9 Re-attach the lamp connector to the projector. The locking tab should
engage when the connector is fully plugged in.

Red LED behavior and projector errors
If the projector is not functioning properly and the LED is blinking red, consult Ta b le 4 to determine a possible cause. There are two-second pauses
between the blinking cycles. Visit our website for more details on the red
LED error codes.
Table 4: LED Behavior
Red LED Behavior Explanation
One (1) blink The lamp won't strike after five (5)
attempts. Check the lamp and lamp door
installations for loose connections.
Two (2) blinks The lamp counter hours have exceeded
lamp life hours. Replace the lamp and
reset the lamp hours counter.
Three (3) blinks The projector has shut down. Check to
see if the lamp door is open. If the lamp
door is closed, toggle off the projector
and wait one minute, then toggle the projector on again. If the lamp does not strike
after one minute, replace the lamp. Contact Technical Support for repair if replacing the lamp does not solve the problem.
Four (4) blinks The fan has failed. Contact Technical Sup-
port for repair or replacing the fan.
Five (5) blinks The projector is overheating. Check for a
blocked air vent (page 16). Contact Technical Support for repair if clearing the
vents/screens does not solve the problem.

Communication configuration
To control the projector from an LCD control panel, connect an RS-232 cable
to the serial control connector on the projector and set your computer’s
serial port settings to match this communication configuration:
Command format
All commands consist of 3 alpha characters followed by a request, all
enclosed in parentheses. The request can be a read request (indicated by a
“?”) or a write request (indicated by 1 to 4 ASCII digits).
A read request format: (AAA?) where
( starts the command
AAA denotes the command
? denotes the read request
) ends the command
A read command returns the range and the current setting, for example
:
A write request example: (AAA####) where
( starts the command
AAA denotes the command
#### denotes the value to be written
(leading zeros not necessary)
) ends the command
Some commands have ranges, while others are absolute. If a number
greater than the maximum range is received, it is automatically set to the
maximum number for that function. If a command is received that is not
understood, a “?” is returned. With absolute settings, “0” is off, 1-9999 is on.
The one exception is the Power command, where 0 is off and 1 is on
.
