Calculation of the projection distance for each projection lens (for PT-D9510U)
If there is no reference made to the require picture size, calculate the projection distance using an expression
below after obtaining the diagonal measurement (inch) of the screen you will use.

ET-D95LE1
(1.5 — 2.5 : 1)
ET-D95LE2
(2.5 — 4.0 : 1)
ET-D95LE3
(4.0 — 7.0 : 1)

Adjusting projector feet
The four feet on the bottom of the projector are adjustable for the height ( 0 mm / 0" to 25 mm / 1") and can be
used for its adjustment when the installation position is not level.
