*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-D75LE90) is attached, the projection relation between the screen and the projector differs from that of
other lenses. Refer to “For the Fixed-focus Lens (Model No.: ET-D75LE90)” (
x
page 36) for details.
