Note: (*1) • Although this message will be automatically disappeared after around 3 minutes, it will be reap-
peared every time the power is turned ON.
(*2) • Lamps have a finite product life. Lamps are characterized by the fact that, after long hours of usage, a
lamp will no longer light up, or the lamp will break or burst, etc. This unit is equipped with an automatic shut-
down function, such that the power will automatically be turned OFF when lamp usage time has reached 2,000
hours. Please be aware, however, that among lamp types, there are major differences in product lifetimes; a
lamp may thus fail to light even prior to the functioning of the automatic shut-down function of this unit.
Caring Of The Transparent Area Of Filter Cover And The Dust-detecting Window
The transparent area of filter cover and the dust-detecting window should be cleaned for normal operation of the
optical dust detecting system. Please pay attention not to remain fiber or fragment of cloth inside the duct.

2. After making sure that the projector has cooled
adequately, remove the fi lter cover.

a swab or a soft cloth.
4. Remove the air fi lter.

down it.
