*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. For details, refer to "Fixed‑focus Lens (Model No.: ET‑D75LE95, ET‑D75LE90)" (x page 39).
