Unpacking and Setting Up
19
Your projector should be directly in front of the screen or
wall, facing straight ahead (at a 90-degree angle to the
surface).
If the image is too low, you can raise it by extending the feet
and tilting the projector up. This causes the image to lose its
rectangular shape, but the projector will correct it
automatically. If necessary, you can adjust the shape using
the keystone buttons on the remote control or the Visual
Setup menu. See page 26 for instructions.
The farther you place the projector from the screen or wall,
the larger the image will be.
The following tables list the distances required for various image sizes (measured diagonally).
Note that the zoom adjustment also affects image size.
