Before Setting Up Your Projector
1-3. Selecting the lens unit
This section provides the guideline information on how to select a screen size, projector mounting position, and type of lens
units, which is appropriate for your presentation purposes. Select the lens unit for your projector according to the environment
in which it is installed.
Note that all descriptions given in this manual assume that the angle of projection is zero degree. In case of projection from an
upper position or from the right or left, it is necessary to calculate the width for the minimum projected image that is a little
larger than the screen size.
