Front projection, ceiling mounting

For ceiling mounting, you need the ceiling mount kit 
designed for this projector. Ask a specialist for installa-
tion. 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 24.

•  When the projector is mounted on the ceiling, im-

ages may appear darker than those projected in 
the case of tabletop mounting. This isn’t a product 
malfunction.

•  Ask your installation specialist to provide a breaker.
 

When you do not use the projector, be sure to shut 
down the main power by the breaker.

•  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 IN-

STALLATION menu to MIRROR. See page 24.

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 inches) 

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 alti-

tude of 1500 meters or higher. Use at an altitude of 
1500 meters or higher may affect the projector’s life.
