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 p\
rojection distance.For PT
