Cleaning the Filter
Important!
Important!
z Continued use of the projector after dust has 
accumulated around its intake vents or in the 
filter can cause overheating of internal projector 
components, which can lead to loss of projection 
brightness and malfunction. Use a vacuum 
cleaner to carefully clean dust from the 
projector’s intake vents and the filter.
z Vacuum the filter from the outside. Strong 
vacuuming power inside the filter can cause 
components to become detached.
z If cleaning cannot remove all of the dirt and dust 
from the filter, replace it with a new YA-F10 or 
YA-F20.
z Do not wash the filter in water. Doing so will 
cause a loss of filter performance.
Use a vacuum cleaner to carefully clean dust from the 
filter.
