The POWER
indicator flashes in
red when the
projector is on.
• 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
It is recommended that the lamp be replaced after approximately 1,500 cumulative hours of use or when you
notice a significant deterioration of the picture and colour quality. The lamp usage time can be checked with the
On-screen Display. (As the usage environment can vary significantly, the projector lamp may not operate for 1,500
hours.)
CAUTION
• Intense light hazard. Do not attempt to look into the aperture and lens while the projector is operating.
