Air filter

Please check and clean the air filter periodically. If the air filter becomes clogged
by dust or the like, internal temperatures rise, which could cause a fire, a burn or
malfunction to the projector. When the indicators or a message prompts you to
clean the air filter, comply with it as soon as possible. Note that the projector may
shut down, when the projector heats too much.
Please replace the air filter when it is damaged or too soiled. Preparation of a new
air filter is recommended. To prepare a new air filter, contact with your dealer and
tell the air filter type number.
Type number = MU03642
