NOTE
• A lamp has a fi nite 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.
