14-ENGLISH
If you are using a projection screen size not listed in these Operating Instructions, measure the diagonal screen
size SD (m). Then use the calculation methods provided to determine projection distance (L1) and the distance
from the top of the projector to the bottom edge of the screen (A1)
.
Establishing dimensions L1 and A1 allows you to calculate all other dimensions.
(Units for calculations: m) (Note that the values obtained in the following calculations are approximations.)
