Setting up your projector (continued)
Front projection, ceiling mounting
For ceiling mounting, you need the ceiling mount
kit designed for this projector. Ask a specialist for
installation. For details, consult your dealer.
• The warranty on this projector does not cover any
damage caused by use of any non-recommended
ceiling mount kit or installation of the ceiling mount
kit in an improper location.
• When using the projector mounted on the ceiling,
set IMAGE REVERSE in the INSTALLATION menu
to MIRROR INVERT. See page 32.
• When the projector is mounted on the ceiling,
images may appear darker than those projected in
the case of tabletop mounting. This isn't a product
malfunction.
• Ask your installation specialist to provide an A/C
power switch. When you do not use the projector,
be sure to shut down the main power by the
switch.
• Do not install the projector where the exhaust vents
are exposed to air emitted by an air conditioning.
Such installation may cause a breakdown.
• Do not install the projector near a fire alarm
because it emits hot air from its exhaust vents.

Rear projection

Ask a specialist for installation. For details, consult
your dealer.
• For rear projection, set IMAGE REVERSE in the
INSTALLATION menu to MIRROR. See page 32.
Caution:
• Placing the projector directly on a carpet impairs
ventilation by the fans, causing damage or failure.
Put a hard board under the projector to facilitate
ventilation.
• Place the projector at least 50 cm (or 20 inch) away
from the wall to prevent the air inlet grille and the air
outlet grilles that emit hot air from being blocked.
• Do not use the projector in the following locations
and manners, which may cause fire or electric
shock.
• In a dusty or humid place.
• In a sideways position, or with the lens facing
down.
• Near a heater.
• In an oily, smoky, or damp place such as a kitchen.
• In direct sunlight.
• Where the temperature rises high, such as in a
closed car.
• Where the temperature is lower than +41ºF (or
+5ºC) or higher than +95ºF (or +35ºC ).
• Keep foliage plants and pets away from the
projector. The temperature around the exhaust
vents and that of the cabinet on the top of the
exhaust vents become high. Take special care for
small children.
Important:
• We don't recommend using the projector at an
altitude of 1500 meters or higher. Use at an altitude of
1500 meters or higher may affect the projector's life.
