may result in a breakdown.
• Thisprojectorusesahigh-pressuremercurylamp
as the light source. The high-pressure mercury
lamp may explode or fail to illuminate permanently
because of an impact, scratch, or deterioration
through use. The period of time until explosion or
permanent failure to illuminate varies considerably
from lamp to lamp, depending on operation
conditions. Therefore, the lamp may explode soon
after the start of use.

you use it beyond its replacement period. When the
instruction of lamp replacement appears, replace it
with a new one immediately even if the lamp is still
lighting normally.
• Whenthehigh-pressuremercurylampexplodes,
glass fragments will scatter inside or outside the
lamp box and the gas charged inside the lamp
will diffuse inside or outside the projector. The gas
inside the lamp contains mercury. Be careful not
to breathe it or avoid it from entering your eye or
mouth. If you should breathe it or if it should enter
your eye or mouth, see a doctor immediately.
• Intheeventthatthehigh-pressuremercury

scattered inside the projector. Ask your dealer to
replace the lamp and to inspect the inside of the
projector. When you clean or replace the lamp by
yourself, be sure to hold the handle of the lamp.
You may get injured by glass fragments.
• Whenremovingthelampfromtheceiling-mounted

fragments from scattering.
