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 32.

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.

Caution:

Installation must be done by a qualified professional.

When the projector is installed on the ceiling using the ceiling mount kit, it is recommended to hold the mount kit and the projector using a metal bar or wire in addition to the mount kit fixing screws to prevent the projector from falling due to an earthquake or other cause. For that purpose, use a metal bar, wire, or screw that bears a load of at least 70 kgf. When using a metal wire, secure one end to a screw hole marked with an arrow on the rear terminal panel and the other end to the mount

kit. (Don’t use screw holes without arrow marks.) In this case, make sure that the screw is inserted in the projector at least 5 mm. The length of the screw should be 20 mm or shorter. Also make sure that no electrical current is flowing in the mount kit due to current leakage or other cause.

Ask a specialist for installation. For details, consult your dealer.

For rear projection, set IMAGE REVERSE in the

INSTALLATION menu to MIRROR. See page 32.

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 intake vents and the exhaust vents 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 ).

Keep foliage plants and pets away from the projector. The temperature around the exhaust vents and that of the cabinet on the top of the exhaust vents become high. Take special care for small children.

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.
