Replacing the unit
Lamp unit
The lamp unit is a consumable component. Refer to “When to replace the lamp unit” (
x page 135) for details 
about the replacement cycle.
When purchasing the optional Replacement Lamp Unit (Model No.: ET -LAEF100), 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
 
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 i\
ts 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 th\
e 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 d\
ealer for 
correct methods of disposal.
Attention
 
f Panasonic takes no responsibility for any damage or malfunction of the p\
roduct 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.
 
f A Phillips screwdriver is necessary when replacing the lamp unit.
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. 
Time for replacement
When [LAMP POWER] is constantly set to [NORMAL] without switching to other modes = 6 000 hours
When [LAMP POWER] is constantly set to [ECO] without switching to other modes = 8 000 hours
but the lamp may go off before the time above mentioned has elapsed depending on individual la\
mp 
characteristics, usage conditions, and the installation environment. It \
is recommended that the Replacement lamp 
unit be prepared earlier.
In order to predict the lamp replacement time, please refer to the lamp runtime displayed in [ST ATUS] 
( x  page 87) → [RUNTIME] → [LAMP] → [NORMAL]/[ECO]. It also can be obtained by using the following 
formula. (The time which is displayed in [ECO] is the converted usage time when set to [NORMAL].)
Formula for lamp replacement time (rough estimate) = “Lamp runtime \
of [NORMAL]” + “Lamp runtime of 
[ECO]” × 3/4
If the time which is obtained by the above equation 6 000 hours has elapsed, the lamp turns of f automatically after 
approximately 10 minutes, as it will cause malfunction of the projector .
