Adjusting The Feet; Projection Scheme; Installation Geometry - Panasonic PT-DW100U Operating Instructions Manual

Installation (continued)

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. 76)

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.
