Diagonal image size and mounting position
The numbers on the slider measure (b) are the same as the projection distance (a) when the diagonal image
size (S) is 70 inches or more. Because the installation position of the projector changes when (S) is less than 70
inches, the numbers for (a) and (b) differ.
In order to see the stamp and the numbers on the slider scale, you need to slide out the arm extension.
When the diagonal image size is 70 inches or more, mount the 3-axis adjustment unit at the position marked
with a stamp.
When the diagonal image size is less than 70 inches, mount the 3-axis adjustment unit at the position marked
