Replacing the unit
Lamp unit
The lamp unit is a consumable component. Refer to “When to replace the lamp unit” (x page 131) for details about the replacement cycle.
When purchasing the optional Replacement Lamp Unit (Model No.: ET-LAE300), consult your dealer.
It is recommended that you request a qualified technician to replace the lamp unit. Consult your dealer .
Warning
Replace the lamp unit after the lamp has cooled (after waiting at least\
 one hour).The high temperature inside the cover will cause burns.
Notes on the replacement of the lamp unit
 fA Phillips screwdriver is necessary when replacing the lamp unit.
 fSince the luminous lamp is made of glass, it may burst if dropped or hit with a hard object. Handle with care.
 fDo not disassemble or modify the lamp unit.
 fWhen replacing the lamp unit, be sure to hold it by the handle because i\
ts surface is pointed and its shape is protruded.
 fThe lamp may rapture. Replace the lamp unit carefully so the glass fragm\
ents of the lamp do not scatter. While attaching the projector to the ceiling, do not work right under the lamp unit or do not conduct work wh\
ile your face is near the lamp unit.
 fThe lamp contains mercury. When disposing of used lamp units, contact your local authorities or d\
ealer for correct methods of disposal.

roduct resulting from use of lamp units which are not manufactured by Panasonic. Use only specified lamp units.
Note
 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 4 000 hours, but the lamp may go off before reaching to 4 000 hours, depending on the characteristics of the individual lamp, 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 4 000 hours has elapsed, the lamp turns off automatically after approximately 10 minutes, as it may cause malfunction of the projector.
