accordance with the projector
setting-up method.

projector on a desk or similar, and
set to “CEILING” when suspending
the projector from the ceiling using

LAMP POWER
This setting changes the lamp
brightness. When set to “LOW”, the
luminance of the lamp is reduced, but
the projector uses less power, and
the operating noise is also reduced.
This can help to extend the lamp’s
operating life. If using the projector in
small rooms where high luminance is
not required, it is recommended that
you set the LAMP POWER to “LOW”.

This setting displays the usage time
for the lamp unit which is currently
being used. If the lamp unit is
replaced in the way described on
page 64, the cumulative usage time
for the lamp unit will be reset to
zero.
NOTE:
BThe lamp’s operating life varies
depending on the usage conditions
(such as the LAMP POWER
setting and the number of times
the power is turned on and off).
