•If the projector is used at an altitude of about 1600 m or higher, set FAN SPEED of the SERVICE item in the

OPTION menu to HIGH. Otherwise, set it to NORMAL. If the projector is used with a wrong setting, it may cause damage to the projector itself or the parts inside.

•Keep a space of 30 cm or more between the sides of the projector and other objects such as walls. Do not place or attach anything that would block the lens or vent holes.

•For the case of installation in special conditions such as on the wall or ceiling, the specied mounting accessories ( 21) and service may be required. Before installing the projector, consult your dealer about your installation.

ENGLISH

•The screen position may shift after installation if the projector is mounted on locations such as the wall or ceiling, due to the exibility of the plastic projector body. If readjustment is necessary, consult with your dealer or service personnel.

•The projected image position and/or focus may change during warm-up (approx. 30 minutes after the lamp is turned on) or when the ambient conditions change. Readjust the image position and/or focus as necessary.

•Since the projector features an ultra short throw, be aware that it is required to select a

screen carefully to have better performance.

-A soft screen such as a pull-down screen may cause serious distortion of a projected image. A hard screen such as a board screen is recommended for use with this projector.

-A high-gain screen such as a bead screen that has narrow viewing angle is not suitable for this projector. A low-gain screen (around 1.0) such as a matte screen that has wide viewing angle is recommended for use with this projector.

-A screen with a weave pattern may cause moiré on the projected image, which is not a failure of the projector. A screen that has less moiré effects is recommended for use with this projector.

WARNING ►Install the projector in a stable horizontal position.

►Place the projector in a cool place, and ensure that there is sufcient ventilation. Do not

place the projector where the air from an air conditioner or similar unit will blow on it directly. ►Do not place the projector anyplace where it may get wet.

►Use only the mounting accessories the manufacturer specied, and leave installing

and removing the projector with the mounting accessories to the service personnel.

►Read and keep the user's manual of the mounting accessories used.

CAUTION ►Avoid placing the projector in smoky, humid or dusty place.

►Position the projector to prevent light from directly hitting the projector’s remote sensor.
