Notes
• When the projector is moved from a cold
location to a warm location, or when the
ambient temperature in the projection room
has risen suddenly, moisture may condense
on the lens or the mirror to blur the projected
pictures.In such a case, leave the projector
for an adequate time (1 to 2 hours, depending
on the room’s condition) before using it so it
adjusts to the ambient temperature.
• If the screen is exposed to direct sunlight or
other strong light, the projected picture
becomes too faint to see. Shut out the light
with curtains or other means.
• If the screen and the projector are not
installed properly, the projected picture may
be distorted.
• If the projector is tilted, the picture may be
distorted.To obtain the best possible picture,
place the projector so it faces the screen
squarely.
(Continued) How to use the foot adjuster
The tilt of the projector can be adjusted using
the foot adjuster.
1) Lift the front of the projector until a tilt
angle desired is obtained and hold down
the foot adjuster release button.
The foot adjuster will stretch.
Release the button to lock in position.
2) Turn the foot adjuster to make fine
adjustment of the height.
Turn clockwise to lift up.
Turn counterclockwise to lower.
3) To put the foot adjuster back, hold down
the foot adjuster release button and
lower the front slowly.
The foot adjuster will put back.
Note
Be sure to hold the projector when putting the
