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 witho

ut 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 projec
 tor 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  protectiv e

 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  installati
 on.  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  dange

rous to you and will void the warranty.
• Only use replacement parts specified by InFocus.  Unauthorized substitutions  may r
 esult 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 lam
 ps may cause electrical shock and fire, and may void the projector 
warranty. 
• Hg – Lamp contains mercury. Ma nage 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 fa ilure 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  projec tor v

ents. Please keep people, food, and drinks at least 3’ (1m) away 
from all projector vents. For ceiling applications, keep people, food and drinks 
out of the keep out area under and around the projector, as indicated by the 
illustration.
Follow these instructions to help ensure image quality and lamp life over the life of 
the pr o
jec

tor. 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 39.4” (1.0m) from the projection screen.
• If you are installing the projector on the ceiling, we strongly recommend using  InFocus a

pproved ceiling mounts for proper  fitting, ventilation and installation. 
Refer to the installation guide that come s with the InFocus Ceiling Mount Kit (p/n 
PRJ-MNT-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. 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.

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.

Displaying an image
Press the Power button.
The Power LED blinks green, and the fans start to  
 run. When the lamp comes on, 
the start up screen displays and the Power LED turns solid green. It can take up to 
a minute for the image to achieve full brightness. Note: When the feature, AC 
Power On, is enabled, the projector automatically turns on when power is 
connected. This allows control of ceiling mounted projectors with a wall power 
switch.
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

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
