Setting Up the Projector
Note
• Allow a margin of error in the value in the diagrams above.
• When the distance from the lens center to the bottom of the image [H] is a negative number, this indicates
that the bottom of the image is below the lens center.
• See page 18 about projection distance [L] and distance from the lens center to the bottom of the image [H].
