Epson PowerLite 1705c Benutzerhandbuch

Clean the air filter and air intake vent after every 100 hours of use. If 
they are not cleaned periodically, they can become clogged with dust, 
preventing proper ventilation. This can cause overheating and damage 
the projector. 

Follow these steps:

1. Turn off the projector. Wait for the 

Power

 light to stop flashing, 

then unplug the power cord.

2. Turn the projector upside down.

3. To clean the intake vent and filter, use a small vacuum cleaner 

designed for computers and other office equipment. If you don’t 
have one, gently clean the vent with a soft brush (such as an 
artist’s paintbrush).

4. If the dirt is difficult to remove or the filter is broken, replace the 

filter as described on page 150. Contact your dealer or call Epson 
at 800-GO-EPSON (800-463-7766) to obtain a new filter.
