							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 touch or block the projector lens with any objects as this can damage 
the projector lens. Scratches, gouges and other lens damage are not covered 
by the product warranty.
• 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/Safety 
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. It must 
be at least 48” (1.2m) from the projection screen.
• 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 PRJ-MNT-UNIV) for mo re information. The warranty does not cover 
any damage caused by use of non-approved  ceiling mount kits or by installing 
in an improper location. To turn the image upside down, see “Ceiling mount” 
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 and the video format determine 
the size of the projected image.
• The image offset is 134% +/-5%.  This  means that if you have an image 60 
inches (1.5 meters) tall from a table- mounted projector, the bottom of the 
image will be 20.4  inches (51.8 cm) above the centerline of the lens.

Connecting a computer source
VGA connection
Connect one end of the provided computer cable to the Computer 1/Computer 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.
HDMI connection
HDMI is a standard, uncompressed, all- digital audio/video interface. HDMI 
provides an interface between sources, su ch 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 either the  HDMI 1 or HDMI 2  connector on the 
projector.
Connecting power
Connect the black power cord to the  Power connector on the rear of the 
projector and to your electrical outlet. If the Power Saving Mode feature is off, the 
Power LED on the Stat us Indicator Panel (
page 11) blinks blue. If the Power Saving Mode feature is on, the Power LED is steady  blue. By default, this feature is off. 
You can change the setting, see page 27. NOTE : Always use the power cord that shipped with the projector.
Optional computer connections
To get sound from the projector, connect an audio cable (optional cable, not 
included) to your computer and to the  Audio 1 or Audio 2  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 to the desktop’s computer 
cable to Computer 1 and the desktop’s monitor cable to the  Monitor out 
connector on the projector.

Displaying an image
Press the Power button.
The Power LED lights blue, and the fans start to run. When the lamp comes on, 
the start up screen displays. It can take  up to a minute for the image to achieve full 
brightness.
No start up screen?  Get help on page 12.
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:
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 co mbination 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 fo r more information about your laptops 
key combination.
No laptop image?  Try pressing the  Auto button on the projector’s keypad or 
Auto Image  button on the remote. Get help on 
page 12.

Adjusting the image
If necessary, adjust the height of the projector by pressing the elevator foot release 
button to extend the foot.
If necessary, rotate the leveling feet located at the rear of the projector.
Position the projector the desired distance from the screen at a 90 degree angle to 
the screen.
See page 6 for a table listing screen sizes and distances.
Adjust the zoom or focus.
If the image is not square, first make sure that the projector is perpendicular to the 
screen. If the image is larger or smaller  on the top or bottom edge of the screen, 
press the top  Keystone button to reduce the upper part of the image, and press 
the bottom  Keystone button to reduce the lower part.
If the left or right side of the screen is larger or smaller the other, you can turn the 
projector to the left or to the right a few degrees to square the image.
Adjust the Contrast or Brightness in the Basic Menu. See page 25 for help with these menu adjustments.
