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. Use the lens cap when the projector is not in use and during 
transport. 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 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 betw een 30 inches (.75m) and 65 inches (1.65m) from 
the screen. To ensure adequate cable access, do not place the projector within 
24 inches (.61m) of a wall or other object.
• If you are installing the projector on the  ceiling, we strongly r
 ecommend 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. To  turn the image upside down, see “Ceiling 
mount” on page 31. We recommend using an InFocus authorized ceiling 
mount.
• Position the projector the  de
 sired 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.
• IN3914 image offset is 107% +/-2%.  Th is 
 means that if you have an image 40 
inches (1 meter) tall from a table-mounted projector, the bottom of the image 
will be 2.8 inches (.07 meter) ab ove the centerline of the lens.
