Replacing the lamp unit
Warning
The lamp unit should only be
replaced by a qualified
technician.
When replacing the lamp, allow it
to cool for at least one hour
before handling it.
BThe lamp cover gets very hot,
and touching it can cause burns.
Notes on replacing the lamp
unit
BThe light generating lamp is
made of glass, so dropping it or
allowing it to hit hard objects may
cause it to burst. Be careful when
handling the lamp.
B Dispose of the removed old lamp
with the same care that would be
taken with a fluorescent light.
B A Phillips screwdriver is
necessary for removing the lamp
unit.
Lamp unit replacement
period
The lamp is a consumable product.
Even when the full life of the bulb
has not been exhausted, the
brightness of the light will gradually
decline. Therefore periodic
replacement of the lamp is
necessary.
The intended lamp replacement
interval is 2 000 hours, but it is
possible that the lamp may need to
be replaced earlier due to variables
such as a particular lamp’s
characteristics, usage conditions
and the installation environment.
Early preparation for lamp
replacement is encouraged.
The lamp will automatically shut off
after approximately 10 minutes
when 2 000 hours of use have been
reached because of a much greater
chance of it exploding after this
time.
NOTE:
BThe projector is not supplied
with a replacement lamp unit.
Please ask your dealer for
details. Lamp unit product 
no.: ET-LAB50
CAUTION:
B Do not use any lamp unit other
than the one with the product
number indicated above.NOTE:
BThe usage hours explained
above are for when “LAMP
POWER” in the “OPTION”
menu has been set to
“STANDARD” and when “AI” in
the “PICTURE” menu has
been set to “OFF”. If “LAMP
POWER” is set to “ECO-
MODE”, or “AI” is set to “ON”,
the life of the lamp can be
extended.
B While 2 000 hours is the
intended replacement interval,
it is not a period of time
covered by warranty.
