Adjusting the feet

The four adjustable feet mounted at the bottom of the projector are level-adjustable (0 mm–15 mm) which can be
used when the floor surface is not horizontal.

Projection scheme

This projector can use any of the four projection schemes. Select the most suitable scheme to the situation of your
location. Use the OPTION menu on the menu screen 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.
