Notes on the replacement of the lamp unit
f A Phillips screwdriver is necessary when replacing the lamp unit.
f Since the luminous lamp is made of glass, it may burst if dropped or hit with a hard object. Handle with care.
f Do not disassemble or modify the lamp unit.
f When replacing the lamp unit, be sure to hold it by the handle because its surface is pointed and its shape is protruded.
f The lamp may rapture. Replace the lamp unit carefully so the glass fragments 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 while your face is near the lamp unit.
f The lamp contains mercury. When disposing of used lamp units, contact your local authorities or dealer for correct methods of disposal.
Attention
f Panasonic takes no responsibility for any damage or malfunction of the product resulting from use of lamp units which are not manufactured
by Panasonic. Use only specified lamp units.
Note
f The 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 3 000 hours, but the lamp may go off before reaching to 3 000 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 3 000 hours has elapsed, the lamp turns off automatically after approximately 10 minutes, as it may
cause malfunction of the projector.
Over 2 800 hours
Over 3 000 hours
Note
f To predict when to replace the lamp, check the lamp runtime displayed at [LAMP : TOTAL] in [STATUS] (x page 92).
f 3 000 hours is only the target for replacement and not the warranty time.
