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.

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.
Caring For The Air Filter
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.
