Maintenance and Cleaning
When the projection lamp of the projector
reaches its end of life, the Lamp replacement
icon appears on the screen and LAMP
REPLACE indicator lights yellow. Replace the
lamp with a new one promptly. The timing when
the LAMP REPLACE indicator should light is
depending on the lamp mode.
For continued safety, replace with a lamp of
the same type. Do not drop a lamp or touch
a glass bulb! The glass can shatter and may
cause injury.
Allow a projector to cool for at least one hour
before you open the Lamp Cover. The inside
of the projector can become very hot.

CAUTION
When replacing the lamp because it has stopped illuminating, there is a possibility that
the lamp may be broken.
If replacing the lamp of a projector which has been installed on the ceiling, you should always
assume that the lamp is broken, and you should stand to the side of the lamp cover, not
underneath it. Remove the lamp cover gently. Small pieces of glass may fall out when the
lamp cover is opened. If pieces of glass get into your eyes or mouth, seek medical advice
immediately.
 Note:
- The Lamp replacement icon will not appear when the Display function is set to Off (p.48), during Freeze (p.27), or
Blank (p.28).
- When Mode 2 is selected in the Lamp life control menu, if the projection lamp of the projector reaches its
end of life, the lamp replacement icon appears on the screen, and the projector is turned off automatically
after 3 minutes.
