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.

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.

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.

• 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 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 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 ).

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.

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.
