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.
The possibility of explosion of the lamp increases if 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.
