Maintenance

The air filter unit of this projector consists of a filter cover, two kinds of filters, and

a filter frame. The new double large filters system is expected to function longer.

However, please check and clean it periodically to keep ventilation needed for

normal operation of the projector.

When the indicators or a message prompts you to clean the air filter, comply with

it as soon as possible. Replace the filters when they are damaged or too soiled.

To prepare new filters, contact to your dealer and tell the following type number.
