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.
The internal temperature is rising.
Please turn the power off, and allow the projector to cool
down at least 20 minutes. After having confi rmed the
following items, please turn the power ON again.
• Is there blockage of the air passage aperture?
• Is the air fi lter dirty?
• Does the peripheral temperature exceed 35°C?

Please immediately turn the power off, and clean or change
the air fi lter referring to the "Air Filter" section of this manual.
After you have cleaned or changed the air fi lter, please be
