t it against a hard surface or drop it.  Please handle with care. fA Phillips screwdriver is required for replacement of the lamp unit. fWhen replacing the lamp unit, be sure to hold it by the handle. fWhen replacing the lamp because it has stopped illuminating, there is a possibility that the lamp may be broken. If replacing the lamp of a projector which has been installed on the ceiling, you sho\
uld always assume that the lamp is broken, and you should stand to the side of the lamp cover, not underneath it. Remove the lamp cover gently. Small pieces of glass may fall out when the lamp cover is opened. If pieces of glass get into your eyes\
 or mouth, seek medical advice immediately. fThe lamp may be ruptured. Care should be taken not to scatter pieces of the broken lamp glass when replacing the lamp unit. Pieces of the broken lamp may fall from the lamp unit especially w\
hen the projector is mounted on the ceiling, so when replacing the lamp unit do not stand directly underneath it or position \
your face close to it. fThe lamp contains mercury. Consult your local municipality or your dealer about correct disposal of used lamp units.

 fThe model numbers of accessories and optional accessories are subject to\
 change without prior notice.
When to replace the lamp unit
The lamp unit is a consumable component. Since its brightness gradually \
decreases over time, it is necessary to replace the lamp unit regularly. The estimated duration before replacement is 5 000 hours, but the lamp may go off before 5 000 hours has elapsed depending on individual lamp characteristics, usage conditions, \
and the installation environment. It is recommended that the Replacement lamp unit be prepared earlier.
If you continue to use the lamp unit after 5 000 hours has elapsed, the lamp turns off automatically after approximately 10 minutes, as it will cause malfunction of the projector.
