Setting up your projector
Before setting up
Before setting up the projector, check the operating environment.
If the environmental requirements are not satisfi ed, the projector may break down or fail.
Setting up the screen
Install the screen perpendicularly to the projector. If the screen can not be installed in such a way, adjust the
projection angle of the projector. (See page 12.)
• Install the screen and projector so that the projector's lens is placed at the same height and horizontal position of
the screen center.
• Do not install the screen where it is exposed to direct sunlight or lighting. Light directly refl ecting on the screen
makes the projected images whitish and hard to view.
Screen size and projection distance
Refer to the following table to determine the screen size and projection distance.
• For the aspect ratio setting, see page 22.
• The fi gures in the tables are approximate and may be slightly different from the actual measurements.
