Care and maintenance
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 contact with 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.
BAfter having removed the old
lamp, carelessly discarding it can
cause the lamp to burst. Dispose
of the lamp with the same care
that would be taken with a
fluorescent light.
BA Phillips screwdriver is
necessary for removing the lamp
unit. Make sure that your hands
are not slippery when using the
screwdriver.
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.
A lamp that has exceeded 2 000
hours of use has a much greater
chance of exploding. In order to
prevent the lamp from exploding,
the lamp will be automatically shut
off when 2 000 hours of use have
been reached.
NOTE:
BThe projector is not supplied
with a replacement lamp unit.
Please ask your dealer for
details. Lamp unit product 
no.: ET-LA735
CAUTION:
BDo not use any lamp unit other
than the one with the product
number indicated above.
NOTE:
BThe usage hours explained
above are for use when the
HIGH setting has been
selected for LAMP POWER in
the OPTION menu. If the
“LOW” setting is selected, the
brightness of the lamp will be
less and life of the lamp can be
extended.
BWhile 2 000 hours is the
intended replacement interval,
it is not a period of time
covered by warranty.
