• If the TEMPERATURE WARNING indicator illuminates, follow the solution listed above and then wait until the projector has cooled down
completely before turning the power back on. (At least 5 minutes.)

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 colour quality. The lamp usage timer can be checked with the On-
screen Display. (See page 34.)

• As the usage environment can vary significantly, the projector lamp may not operate for 1,500 hours.

• For safety, the power will not be turned on from the fourth times when turning on the power without changing the lamp after use for 1,500
hours.
