of the lamp with the same care
that would be taken with a

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 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.
B While 2000 hours is the intended
replacement interval, it is not a
period of time covered by
warranty.

Lamp unit replacement procedure
NOTE:

procedure given in "Turning off
the power" on page 23, and
then disconnect the power
