NOTE • A lamp has 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 projector is equipped with an automatic shut-down
function, such that the power will automatically be turned off when lamp usage
time has reached 2000 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 projector.
