Front projection, ceiling mounting

For ceiling mounting, 

you need the ceiling 

mount kit designed 

for this projector. Ask 

a specialist for instal-

lation. For details, con-

sult 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 25.

•  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 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 projec-

tion, set IMAGE 

REVERSE in the 

INSTALLATION menu to MIRROR. See page 25.

TRIGGER terminal

The TRIGGER terminal on the rear of the projector 
is a terminal that outputs a 12 V signal to control an 
externally connected device (electric screen) when 
images are projected. 

To use the TRIGGER terminal, set TRIGGER OUT to 
ON in the INSTALLATION menu. (The factory default is 
OFF.) Use the following steps to change the setting.

4.  Press the MENU button. 

Caution:

•  Do not use the signal output from the TRIGGER 

terminal as a power for other devices. 

•  Do not link the TRIGGER terminal with an audio 

terminal of other device because that device may 
be damaged. 

•  The rated current for the TRIGGER terminal is 200 mA. 

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

•  For information about electric screens, please con-

tact screen manufacturers.

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 or upside-down position.

•  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 ).
