Important Operating Considerations for Safety
 Place the projector in a horizontal position no greater than 15 degrees 
off axis.
 Locate the projector in a well-ventilated area without any obstructions 
to intake or exhaust vents. Do not place the projector on a tablecloth or 
other soft covering that may block the vents. 
 Locate the projector at least 4 (1.2 m) away from any heating or cooling 
vents.
 Use only InFocus-approved ceiling mounts.
 Use only the power cord provided. A surge-protected power strip is 
recommended. 
 Refer to this manual for proper startup and shutdown procedures.
 In the unlikely event of the lamp rupturing, discard any edible items 
placed in the surrounding area and thoroughly clean the area along all 
sides of the projector. Wash hands after cleaning the area and handling 
the ruptured lamp. This product has a lamp which contains a very 
small amount of mercury. Dispose of it as required by local, state or fed-
eral ordinances and regulations. For more information see 
www.eiae.org
.
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 section at 
the end of this users guide.
