ON USE/INSTALLATION
Do not put your weight on this projector.
You could fall or the projector could break, and injury
will result.
Be especially careful not to let young children stand
z
or sit on the projector.
Do not place the projector in extremely
hot locations.
Doing so will cause the outer casing or internal com-
ponents to deteriorate, or result in fire.
Take particular care in locations exposed to direct
z
sunlight or near stoves.
Always disconnect all cables before mov-
ing the projector.
Moving the projector with cables still attached can
damage the cables, which will cause fire or electric
shocks to occur.
ACCESSORIES
Do not use the old lamp unit.
If used it could cause lamp explosion.
If the lamp has broken, ventilate the room
immediately. Do not touch or bring your
face close to the broken pieces.
Failure to observe this will cause the user to absorb
the gas which was released when the lamp broke and
which contains nearly the same amount of mercury as
fluorescent lamps, and the broken pieces will cause
injury.
If you believe that you have absorbed the gas or that
the gas has got into your eyes or mouth, seek medi-
cal advice immediately.
Ask your dealer about replacing the lamp unit and
check the inside of the projector.
Do not use projectors with the adjustable
feet or lens cover removed.
If this not observed, the sets will not operate correctly
or accidents will result.

Lens Focus
Do not adjust the lens focus in the initial period after
switching the projector on. The high clarity projector
lens is thermally affected by the light from the light
source, making the focus unstable in the period just
after switching on. Please allow a warm-up time of at
least 30 minutes before adjusting the lens focus.
