*1 The throw ratio is based on the value during projection with the projected image size of 3.81 m (150").
*2 When the Fixed-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 the Fixed-focus Lens (Model No.: ET-D75LE90)" (x page 37) for details.
Formula for calculating the projection distance per projection lens
To use a projected image size not listed in this manual, check the projected image size SD (m) and use the
respective formula to calculate projection distance.
The unit of all the formulae is m. (Values obtained by the following calculation formulae contain a slight error.)
When calculating a projection distance using image size designation (value in inches), multiply the value in inches
by 0.0254 and substitute it into SD in the formula for calculating the projection distance.
