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. 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.

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. IN2124a 
must be at least 45.3” (1.2m) from the projection screen, and IN2126a must 
be at least 55.4” (1.4m) 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 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 28. 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.
