*1
When the Fixed-focus Lens (Model No.: ET-DLE030, ET-DLE035) 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, ET-DLE035)” (
x
page 38) for details.
*2
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,
ET-DLE035) is attached, the throw ratio is based on the value during projection of 2.54 m (100") projected image size.
*3
When the Fixed-focus Lens (Model No.: ET-DLE055) is attached, the lens shift is not possible, therefore the height position (H) becomes the fixed
value of SH/2.
