Adjusting the feet
The four adjustable feet (p. 14) mounted at the bottom of the projector are level-adjustable (0 mm–15 mm) which
can be used when the mounting surface is uneven.

Projection scheme
All four combinations of Front, Rear, Ceiling or Floor mounting are available. Use the INSTALLATION menu to
choose the desired projection scheme. (p. 78)
Installation geometry
When planning the projector and screen geometry, refer to the figures below and the information on the next page
for reference. After the projector is roughly positioned, picture size and vertical picture positioning can be finely
adjusted with the powered zoom lens and lens shifting mechanism.

* For PT-D12000U: H = 0 to SH
For PT-DZ12000U: H = -0.1 × SH to 1.1 × SH
* However, if the ET-D75LE5 has been installed,
the value will be fixed at H=SH/2 for both the
PT-D12000U and PT-DZ12000U. If the ET-D75LE6
has been installed, the values will be H = 0.1 × SH
to 0.9 × SH for the PT-D12000U, and H = 0 to SH
for the PT-DZ12000U.
