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 26.
• 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 fi re 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 26.
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 fi re 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 ).
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.

200 mA. If you use a current exceeding this rating,
a failure may occur.
