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.
