INSTALLING THE PROJECTOR Determining the Distance to the Screen The projected image size is determined by the distance between the projector lens and the screen. Select the place where the desired image size is obtained according to the figure shown below. The image size can be adjusted using the Zoom lever by the lens. 9.1 m (29.9′) 6.0 m (19.7′) 4.5 m (14.8′) 2.4 m (7.9′) 1.2 m (3.9′) Zoom (max.) Zoom (min.) INSTALLING THE PROJECTOR Optical axis when image is projected at right angle to the screen. Screen H1 and H2: H1 is the height of the screen from the intersection of optical axis and screen surface, and H2 is the height of the intersection when an image is projected at right angle to the screen.

If the installation position is too close, the image is out of focus. If the installation position is too far, the screen becomes dark. • The sizes in the above table have been obtained assuming that the aspect ratio is 4:3. They may vary from the actual sizes depending on the type of the projected image. For the relationship between the screen size and projection distance, see the table on page 85. 20
