Note: (*1) • Although this message will be automatically disappeared after around 3 minutes, it will be
reappeared 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.
