Replacement
Lamp unit
The lamp unit is a consumable component. Refer to “When to replace the lamp unit” (x page 166) for details
about the replacement cycle.
When purchasing the optional Replacement lamp unit (Model No.: ET-LAD70 (1 pc), ET-LAD70W (2 pcs)), consult
your dealer.
It is recommended that you request a qualied 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.
Checking the lamp unit to be replaced
1) Check the status of the lamp indicators <LAMP1>/<LAMP2>.
f The lamp unit corresponding to the lamp indicator that is lit in red is required to be replaced.
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 that 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 specied 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 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.
