Maintenance
Maintaining the air-filter  (continued)
►Before taking care of the air-filter, make sure the power switch 
is off and the power cable is not plugged in, then allow the projector to cool 
sufficiently. Taking care of the air-filter in a high temperature state of the projector 
could cause an electric shock, a burn or malfunction to the projector.
►Use only the air-filter unit 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.WARNING
• A filter unit of specified type will come with the replacement lamp 
for this projector. Replacing the filter unit at the same time with the lamp is 
recommended.
• Please reset the filter time only when you have cleaned 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. NOTE
