and the projected image. Adjust the brightness, color and/or
contrast in the Main menu. See page 22.

The lamp begins to lose brightness when it has been in use for
•
a long time. Replace the lamp as described in "Replacing the
Projection Lamp" on page 31.

A minor power surge may cause the lamp to shut off. Turn off
•
the projector, wait at least a minute, then turn it back in.
