							3 Important Operating Considerations for Safety
• Refer to this guide for proper startup and shutdown procedures.
• Follow all warnings and cautions in this manual and on the projector.
• Place the projector in a horizontal position no greater than 15 degrees 
off axis.
• Locate the projector at least 4 (1.2m) away from any heating or cooling 
vents.
• Do not block ventilation openings. Locate the projector in a well-
ventilated area without obstructions to intake or exhaust vents. Do not 
place the projector on a tablecloth or other soft covering that may block 
the vents.
• Do not place the projector in direct sunlight, humid, greasy or dusty 
places or in places where the projector may come into contact with 
smoke or steam.
• Do not look directly into the lens while the projector is being used.
• Do not drop the projector.
• Do not spill liquid on the projector. Spilled liquid may damage the 
projector.
• Use the power cord provided. Connect the power cord to a receptacle 
with a protective safety (earth) ground terminal. A surge-protected 
power strip is recommended.
• Do not overload wall outlets.
• When disconnecting the power cord, hold the plug, not the cord.
• Wash hands after handling the cables supplied with this product.
• The projector remote control uses batteries. Make sure the batteries’ 
polarity (+/-) is aligned correctly. Dispose of used batteries in 
accordance with local disposal laws.
• Use an InFocus approved ceiling mount kit for proper fitting, 
ventilation and installation.  The warranty does not cover any damage 
caused by use of non-approved ceiling mount kits or by installing in an 
improper location. 
• When the projector is ceiling mounted, wear protective eyewear to 
prevent eye injury before opening lamp door.
• Refer all service to qualified service personnel. Servicing your own 
projector can be dangerous to you and will void the warranty.
• Only use replacement parts specified by InFocus.  Unauthorized 
substitutions may result in fire, electrical shock, or injury, and may 
void the warranty
• Only genuine InFocus lamps are tested for use in this projector. Use of 
non InFocus lamps may cause electrical shock and fire, and may void 
the projector warranty. 
• Hg – Lamp contains mercury. Manage in accordance with local 
disposal laws. See www.lamprecycle.org.
• The projector uses a high-pressure mercury glass lamp.  The lamp may 
fail prematurely, or it may rupture with a popping sound if jolted, 
scratched, or handled while hot.  The risk of lamp failure or rupture 
also increases as the lamp age increases; please replace the lamp when 
you see the “Replace Lamp” message.
• In the unlikely event of a lamp rupture, particles may exit through the 
projector vents. 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.

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 general 
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.
• Position the projector within 10 feet (3m) of your power source and 
within 6 feet (1.8m) of your video device (unless you purchase 
extension 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, we strongly 
recommend using InFocus approved ceiling mounts for proper fitting, 
ventilation and installation. Refer to the installation guide that comes 
with the InFocus Ceiling Mount Kit (p/n SP-CEIL-UNIV) for more 
information. The warranty does not cover any damage caused by use of 
non-approved ceiling mount kits or by installing in an improper 
location.
• 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 exits the projector at a given angle. IN3902LB image offset is 
115%; IN3904LB image offset is 112.4%. This means that if you have an 
image 10’ high, the bottom of the image will be 1.5 (IN3902LB) and 
1.24 (IN3904LB) above the center of the lens.

Connecting a computer source
DisplayLink or VGA
If you have a Windows or Macintosh computer, connect the USB cable 
between your computers USB port and the projectors DisplayLink 
connector*. Then to begin installation of the DisplayLink software: 
Windows: Follow the instructions on the screen.
Macintosh: A folder will open containing a file named DisplayLink 
Installer.pkg. Open that file and follow the instructions on the screen.
* For detailed DisplayLink instructions and troubleshooting, and to 
download the latest DisplayLink software, go to www.infocus.com/support/displaylink.
Or, connect one end of the provided computer cable to the VGA 1 or VGA 2 
connector on the projector and the other to the VGA connector on your 
computer. If you are using a desktop computer, you will need to disconnect 
the monitor cable from the computer’s video port first (you can connect this 
monitor cable to the Monitor Out connector on the projector, see below).
Connect the black power cord to the Power connector on the side of the 
projector and to your electrical outlet. The Power light on the Status 
Indicator Panel (

Optional computer connections
To get sound from the projector, connect an audio cable (optional cable, not 
included) to your computer and to the Audio In Computer connector on the 
projector. You may also need an adapter.
If you are using a desktop computer and want to see the image on your 
computer screen as well as on the projection screen, connect the computer’s 
monitor cable to the Monitor Out connector on the projector.
NOTE: Only VGA video is sent to the Monitor out connector.
To display a presentation from a USB flash drive, see the Using LitePort 
section on on page 42. This feature converts presentations to JPEG images and eliminates the need for a computer source and can be integrated with 
common wall plates and conference room input/output panels.

plug the USB cable between the projectors DisplayLink connector and your 
computer. Then press the up and down arrow buttons on the remote control 
to move through your slides.
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 
projector’s Serial Control connector. Specific RS-232 commands can be 
found in the Service and Support section of our website.
The projector can be managed by networking software through its Network
(RJ-45) connector. Detailed instructions on this feature can be found on our 
website.

Displaying an image
Touch the Power button.
The Power button blinks green and the fans start to run. When the lamp 
comes on, the start up screen displays and the Power button is steady green. 
It can take a minute for the image to achieve full brightness.
? No start up screen? Get help on on page 19.
Turn on your computer or video device.
The image should appear on the projection screen. If it doesn’t, press the 
Source button on the projector’s keypad or remote.
If you are using a VGA cable to connect your computer to the projector (instead 
of DisplayLink):
If using a laptop, make sure its external video port is active.
Many laptops do not automatically turn on their external video port when a 
projector is connected. Usually a key combination like FN + F8 or CRT/
LCD key turns the external display on and off. Locate a function key labeled 
CRT/LCD or a function key with a monitor symbol. Press FN and the 
labeled function key simultaneously. Refer to your laptops documentation for 
more information about your laptops key combination or go to the InFocus 
website at: http://www.infocus.com/Support/LaptopActivation.aspx. 
? No laptop image? Try pressing the Auto Image button on the keypad. 
Get help 
on page 20.
? Is your laptop connected to the projectors DisplayLink connector? See the 
InFocus DisplayLink Software Users Guide (available on the InFocus 
website at www.infocus.com/displaylink) for troubleshooting information.
