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.
NOTE:	 The	message	 for	filter	 cleaning	 will	be	displayed	 for	one	 minute	 after	the	projector	 is	turned	 on	or	off.	 When	 the	message	 is	
displayed,	clean	the	filters.	The	time	to	clean	the	filters	is	set	to	[OFF]	at	time	of	shipment.
To	cancel	the	message,	press	any	button	on	the	projector	cabinet	or	the	remote	control.
The	two-layer	 filter	on	the	 projector	 improves	 cooling	and	dust-proof	 capabilities	 compared	with	the	conventional	
models.
The	outsides	(intake	side)	of	the	first	and	second	layer	filters	remove	dust.
To	clean	the	filter,	detach	the	filter	unit	and	the	filter	cover.
Filter	removal	procedure	is	different	depending	on	the	model.
 CAUTION
•	 Before	 cleaning	the	filters,	 turn	off	the	 projector,	 disconnect	 the	power	 cord	and	then	 allow	 the	cabinet	 to	cool. 	
Failure	to	do	so	can	result	in	electric	shock	or	burn	injuries.
