Notes on replacing the lamp

B The 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.

lamp, carelessly discarding it can
cause the lamp to burst. Dispose
of the lamp with the same care
that would be taken with a

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 2000 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 2000
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 2000 hours of use have
been reached.
NOTE:
B The projector is not supplied
with a replacement lamp unit.
Please ask your dealer for
details. Lamp unit product
no.:

CAUTION:

Do not use any lamp unit other
than the one with the product
number indicated above.
NOTE:
B
The usage hours explained
above are for use when the
HIGH setting has been
selected for LAMP POWER in
the OPTION2 menu. If the
LOW setting is selected, the
brightness of the lamp will be
less and life of the lamp can be
extended.
B
While 2000 hours is the
intended replacement interval,
it is not a period of time
covered by warranty.

has been set to “HIGH”), the projector will switch to standby mode after
approximately 10 minutes of operation. The steps
