Setting Up 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 illustra-
tion shown below.

H1 and H2: The height of the screen from the intersection of optical axis and screen surface when an
image is projected at right angle to the screen.
Install the projector at the position where the projection distance is between approxi-
mately 1.2 m (3.9') to 9 m (29.5'). If the installation position is too close or too far, the
image is out of focus or the screen becomes dark, respectively.
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
119.
You can also adjust the image size with the zoom function (P37).
