*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, it 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 fixed-focus lens (Model No.: ET-DLE030)" (x page 33) for details.
*3 When the fixed-focus lens (Model No.: ET-DLE055) is attached, the lens shift is not possible. The height position (H) becomes SH/2.
