Notes on the replacement of the lamp unit
f
The luminous source of the lamp is made of glass and may burst if you hit it against a hard surface or drop it.
Please handle with care.
f
A Phillips screwdriver is required for replacement of the lamp unit.
f
When replacing the lamp unit, be sure to hold it by the handle.
f
When 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 should 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.
f
The luminous lamp may be ruptured. Care should be taken not to scatter pieces of the broken luminous lamp
glass when replacing the lamp unit. Pieces of the broken luminous lamp may fall from the lamp unit especially
when 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.
f
The luminous lamp contains mercury. Consult your local municipality or your dealer about correct disposal of
used lamp units.
Attention

by Panasonic. Use only specified lamp units.

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 luminous lamp
may go off before 5 000 hours has elapsed depending on individual lamp unit 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.
