Projection distance of each projection lens
A ±5 % error in listed projection distances may occur.
When [GEOMETRY] is used, distance is corrected to become smaller than the specied image size.
For PT-DZ21K2
r When the image aspect ratio is 16:10

*1 The throw ratio is based on the value during projection with the projected image size of 3.81 m (150").
*2 When the xed-focus lens (Model No.: ET-D75LE90) is attached, the projection relation between the screen and the projector differs from that of
other lenses. Refer to “For xed-focus lens (Model No.: ET-D75LE90)” (x page 35) for details.
