► Do not maintain the projector during or immediately after use. 
Handling while the projector is hot could cause burn and/or projector malfunction. 
Before maintaining, make sure that the power switch is off, that the power cord is 
unplugged, and that the projector is adequately cool.
► Use only the specified air filter type. Do not use the projector with the air 
filter or the filter cover removed. Doing so could cause fire and/or projector 
malfunction.
► The air filter should be cleaned periodically. If the air filter becomes blocked 
by dust or other debris, the internal temperature will rise, which could cause 
burns, fire and/or projector malfunction, or reduce the lifetime of the projector.
WARNING
• Please replace the air filter when it is damaged or too dirty to be 
cleaned, and also when the lamp is replaced.
• Only reset the FILTER TIME item when you have cleaned or replaced the air 
filter so that the FILTER TIME remains accurate (
53).
• The projector may display the message “CHECK THE AIR FLOW” or 
automatically turn the power off in order to prevent the internal heat level from 
rising.
