• If the TEMPERATURE WARNING indicator lights up, follow the above possible solutions and then wait until the projector has
cooled down completely before turning the power back on. (At least 5 minutes.)
• If the power is turned off and then turned on again, as during a brief rest, the LAMP REPLACEMENT indicator may be
triggered, preventing the power from going on. Should this occur, take the power cord out of the wall outlet and put it back
in again.
Lamp
The lamp in this projector operates for approximately 1,500 cumulative hours, depending on the usage environ-
ment. It is recommended that the lamp be replaced after 1,400 cumulative hours of use or when you notice a
significant deterioration of the picture and color quality. The lamp usage time can be checked with the On-screen
Display (see page 39).
CAUTION
• Intense light hazard. Do not attempt to look into the aperture and lens while the projector is operating.
• As the usage environment can vary significantly, the projector lamp may not operate for 1,500 hours.
