■ Dimensional relationship
For details on the projection distance (L), refer to "Projected image size and Projection
distance" and "Projection distance formulas" in the Appendix.
Note
z For details on "Projected image size and Projection distance" for projector models other
than PT-MZ880 / PT-MZ780 / PT-MZ680, refer to "Setting up" in the operating instructions
of the projector.
