SAFETY INSTRUCTIONS

CAUTION

The distance of projection may not allow focusing on the peripheral

area of the screen. Adjust the focus to keep the c enter and the

peripheral area of the screen balanced.

This speci

fi

cations are subject to change without notice.

The zoom lens may cause some distortion of the image on the screen

depending on the zoom position.

Distortion may appear on screen if the keystone correction (trapezoidal

distortion correction) is overly adjusted.

Keystone correction (trapezoidal distortion correction) may be limited

with some lenses.

To maintain a certain level of image quality, depending on the lens

model, the adjustable range of the focus and zoom is limited. As a

result, the area around the upper or lower limit of the dialog in the

projected image is not displayed in maximum zoom, but this is not a

malfunction.
