■ Do Not Use in the Following Environments
• Do not install the projector in a humid or dusty location or a position where there is a lot
of oily smoke or cigarette smoke. Optical parts such as the lens and mirror may be
stained, resulting in poor picture quality.
• Do not install close to high-voltage power lines or power sources. The projector may not
operate correctly.
• Do not use the projector on a soft surface such as a carpet or sponge mat. Heat may
accumulate inside the projector, causing a malfunction.
• Do not use the projector in a location that is subject to very high temperatures, very low
temperatures, or high levels of humidity. Doing so may cause a malfunction. The tem-
perature and humidity ranges for operation and the temperature range for storage are
shown below.

■ Do Not Touch the Lens with Bare Hands
Do not touch the lens with bare hands. Doing so may adversely affect picture quality.
■ Install at a Sufficient Distance from Walls and Other Obstructions
If the air intake or
exhaust vent is blocked,
heat will accumulate
inside the projector,
possibly resulting in a
shortened projector life-
time or a malfunction.
Do not install in a
closet, on a bookshelf,
or other narrow location
with poor ventilation.
Install in a well venti-
lated location. (Install
with a minimum of 50
cm (1.6') clearance on
the top and sides, and
50 cm (1.6') to the rear.)
■ Be Careful of Condensation
If the temperature of the room rises suddenly, moisture in the air may condense on the
projector lens and mirror, causing the image to become blurred. Wait until condensation
evaporates and a normal picture is shown.
■ When Using the Projector at Altitudes Greater than 2,300 m
Contact the Canon Customer Support Center if you intend to use this projector at altitudes
of 2,300 m or higher.
