Air Filter Air Filter
WARNING• Please carefully read the “User’s Manual - Safety Guide.
• Before caring, make sure the power switch is off and the power cable is not
plugged in, then wait at least 45 minutes for the lamp to cool sufficiently.
• Use only the air filter of the specified type NJ08081
.
• Do not use the projector with the air filter and filter cover removed. The use without
the air filter could result in damage.
CAUTION
• If the air filter becomes clogged by dust or the like, internal
temperature rises and could cause malfunction. The power is automatically turned
off in order to prevent the projector from overheating internally.
The air filter should be cleaned about every 100 hours. If the indicators or a message
prompts you to clean the air filter, clean the air filter as soon as possible. 
If the soiling will not come off the air filter, or it becomes damaged, then it needs to be
replaced. Please replace the air filter as soon as possible.
memoWhen you replace the lamp, please replace also the air filter.
Turn off the projector, and unplug the power cord. Allow the lamp bulb to cool for at
least 45 minutes.
Apply a vacuum cleaner to the top of the filter cover and
the air filter to clean.
If the soiling will not come off the air filter, or it becomes
damaged, it needs to be replaced.
If the air filter needs to be replaced, contact your dealer
to prepare a new air filter. Tell the dealer your air filter
type.

• 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.
