Cleaning and replacing the air filter
WARNING ►Before taking care of the air filter, make sure the power cable
is not plugged in, then allow the projector to cool sufficiently.
►Use only the air filter of the specified type. Do not use the projector without the
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.
NOTE • Please reset the filter time only when you have cleaned or replaced
the air filter, for a suitable indication about the air filter.
• The projector may display the message such as “CHECK THE AIR FLOW” or
turn off the projector, to prevent the internal heat level rising.
