7. Maintenance
This	section	 describes	 the	simple	 maintenance	 procedures	you	should	 follow	to	clean	 the	filters,	 the	lens,	 the	cabinet, 	
and	to	replace	the	lamp	and	the	filters.
1 Cleaning the Filters
The	air-filter	 sponge	keeps	dust	and	dirt	from	 getting	 inside	the	projector	 and	should	 be	frequently	 cleaned.	If	 the	 filter	
is	dirty	or	clogged,	your	projector	may	overheat.
