I Replacing the lamp cartridge
Important
• Make sure to use the lamp cartridge PJL-112 for
replacement. Other cartridge is not applicable to
this unit.
The lamp used as the source of light is a consumable and will
gradually lose its brightness over the course of usage. It is
recommended that the lamp should be replaced when its usage
exceeds 1000 hours in order to enjoy the best image possible.
"LAMP RUNNING TIME" in the menu group 3 <INITIAL> tells
you how many hours the lamp has been used so far. The LAMP/
COVER indicator also lets you know the lamp replacement timing
by flashing in red after the lamp usage has exceeded 1000 hours.
(See page 14.) A message to replace the lamp will be displayed on
the screen as well. Follow the following steps to replace the lamp
with a new one.
For details, consult the store where this unit was purchased.
