Setting-up
Projection methods
In way of installing projector, any one of the following four projection methods
are used. Select whichever projection method matches the setting-up
method. (The projection method can be set from the OPTION2 menu. Refer
to page 41 for details.)

NOTE:
BYou will need to purchase the separate ceiling bracket (ET-PK730) when
using the ceiling installation method.

Projection distances
Setting-up dimensions which are not given in the above table can be
calculated using the formulas below.
If the screen size (diagonal) is SD (m), then the following formula is used to
calculate the projection distance for the wide lens position (LW) and the
projection distance for the telephoto lens position (LT).
For 16:9 aspect ratios, the following formula can be used to calculate the
projection distance.
NOTE:
BThe dimensions in the table above and the values obtained from the
above formulas may contain slight errors.
BIf you use the projection distance for the 16:9 screen, the
4:3 projection image overflows the screen at the top and
bottom.
BIf you set up the projector vertically, it may cause to
damage the projector.
B
It is recommended that you set up the projector in
a place that is tilted at less than
±30°. Setting up
the projector in places that are tilted at more than
±30° may cause malfunctions.
