• 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

in again.
Lamp
The lamp in this projector operates for approximately 2,000 cumulative hours, depending on the usage environ-
ment. It is recommended that the lamp be replaced after 1,900 cumulative hours of use or when you notice a
significant deterioration of the picture and colour quality. At this point, take the projector to your nearest Authorised
Sharp Iudustrial LCD Products Dealer or Service Centre to have the lamp replaced. 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 2,000 hours.
