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.
