Air ﬁlter

WARNING ►Do not replace the air ﬁlter during use or immediately after use. Handling while the projector is in a high temperature could cause a burn and/or malfunction to the projector. Before operating, make sure that the power switch is off, that the power cord is not plugged in, and that the projector is cool adequately. ►Use only the air ﬁlter of the speciﬁed type. Do not use the projector with the air ﬁlter and ﬁlter cover removed.

►Avoid wetting the projector or inserting liquids in the projector. It could result in a ﬁre, an electric shock, and/or malfunction to the projector.

CAUTION ►Please replace the air ﬁlter when it is damaged or too soiled, and also when you replace the lamp.

When the indicators or a message prompts you to clean the air ﬁlter, clean the air ﬁlter as soon as possible. If the air ﬁlter becomes clogged by dust or the like, internal temperatures rise and the power may be automatically turned off for malfunction prevention.

1. Disconnect all the connectors and adapters that were connected to the projector’s ports. Then slowly turn the projector so that the lens-side is facing

up. Please be careful for a projector not to fall. While the projector is placed lens-side up, hold the projector.
