*1 The throw ratio is based on the value during projection of 2.03 m (80") projected image size. When the Fixed-focus Lens (Model No.: ET-DLE030) is
attached, the throw ratio is based on the value during projection of 2.54 m (100") projected image size.
*2 When the Fixed-focus Lens (Model No.: ET-DLE030) 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-DLE030)” (
x
page 37) for details.
*3 When the Fixed-focus Lens (Model No.: ET-DLE055) is attached, the lens shift is not possible, therefore the height position (H) becomes SH/2.
