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.)

(Factory default setting)

NOTE:
B You will need to purchase the separate ceiling bracket (ET-PK730) when

using the ceiling installation method.

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:
B The dimensions in the table above and the values obtained from the

above formulas may contain slight errors.

B If you use the projection distance for the 16:9 screen, the

4:3 projection image overflows the screen at the top and
bottom.

B If 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.
