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 guide for proper startup and shutdown procedures.
• This product has a lamp which contains a very small amount of mer-
cury. Wash hands after cleaning the area and handling the ruptured
lamp. Dispose of it as required by local, state or federal ordinances and
regulations. For more information see www.eiae.org.
• In the unlikely event of a lamp rupture, particles may exit through the
projector side vents. When the projector is turned on, keep people,
food, and drinks out of the "keep out" area under and around the pro-
jector, 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.
