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:
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 2 000 hours is the
intended replacement interval,
it is not a period of time
covered by warranty.
