Projection distance of each projection lens
A ±5 % error in listed projection distances may occur.
When [GEOMETRY] is used, distance is corrected to become smaller than the specified image size.

*1
The throw ratio is based on the value during projection with the projected image size of 3.81 m (150").
*2
When the Fixed-focus Lens (Model No.: ET-D75LE95, ET-D75LE90) is used, the projection relation between the screen and the projector differs
from that of other lenses. Refer to “Fixed-focus Lens (Model No.: ET-D75LE95, ET-D75LE90)” (
x
page 42) for details.
