For instructions on projecting images, see “Projecting Images (Basic Operation)” of the
user’smanual(CD-ROM)suppliedwiththeprojector.
- At “Installation” or “Settings” on the on-screen menu, select “Ceiling/Front” for the projec-
tion method.
- For projectors with a test pattern function, adjustment is easier by projecting the test pat-
tern.
The descriptive diagrams only indicate changes in the projected image for one adjustment
at a time. In real circumstances, distortion is compound.
1. Adjust the projector’s orientation in the horizontal
direction.
Turn the horizontal tilt adjustment knob and adjust so that the top and bottom edges of the pro-
jected image are parallel.
- The adjustment range is ±5°.
