Arrangement

Refer to table T-1 and figures F-1 and F-2 at the end of User's Manual (concise) to determine the screen size and projection distance.

The values shown in the table are calculated for a full size screen: 1280 x 800

a Screen size (diagonal) b1 , b2 Projection distance (±8%) c1 , c2 Screen height (±8%)

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

•The screen position may shift after installation if the projector is mounted on locations such as the wall or ceiling, due to the flexibility 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.

NOTE • The projector may make a rattling sound when tilted, moved or shaken, since a flap to control the air flow inside of the projector has moved. Be aware that this is not a failure or malfunction.

WARNING ►Place the projector in a stable horizontal position. If the projector falls or is knocked over, it could cause injury and/or damage to the projector. Using a damaged projector could then result in fire and/or electric shock.

•Do not place the projector on an unstable, slanted or vibrational surface such as a wobbly or inclined stand.

•Do not place the projector on its side, front or rear position.

•Consult with your dealer before a special installation such as on the wall or ceiling.
