Projection distance of each projection lens
A ±5 % error in listed projection distances may occur.
In addition, when [GEOMETRY(2D)] and [KEYSTONE] are used, distance is corrected to become smaller than the specified screen size.

*1 The throw ratio is based on the value during projection onto a 2.03 m (80") screen size.
*2 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.
