air filter or the filter cover. It could result in a fire or malfunction to the projector.

►Clean the air filter periodically. If the air filter becomes clogged by dust or the like,

internal temperatures rise and could cause a fire, a burn or malfunction to the projector.

the air filter, for a suitable indication about the air filter.

• The projector may display the message such as “CHECK THE AIR FLOW” or
