Authorised LCD Projector Dealer or Service
Centre for repair.

• Securely install the filter cover.

• The warning lights on the projector indicate problems

inside the projector.

• There are two warning lights: a TEMPERATURE

WARNING indicator that warns you when the projector
is too hot, and two LAMP REPLACEMENT indicators
that warn you when to change a lamp.

• If a problem occurs, either the TEMPERATURE

WARNING indicator or the LAMP REPLACEMENT
indicators will light up red. After turning off the power,
follow the procedures given below.

• 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 indicators 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.

It is recommended that the lamp be replaced after approximately 1,000 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 1,000
hours.)

• Intense light hazard. Do not attempt to look into the aperture and lens while the projector is operating.
