Maintenance	and	Cleaning
Filter	prevents	dust	from	accumulating	on	the	optical	elements	inside	the	projector.	Should	the	filters	become	
clogged	with	dust	particles,	it	will	reduce	cooling	fans’	effectiveness	and	may	result	in	internal	heat	buildup	
and	adversely	affect	the	life	of	the	projector.	If	a	Filter	warning	icon	appears	on	the	screen,	clean	the	filters	
immediately.	Clean	the	filters	by	following	the	steps	below.
CAUTION
Do	not	operate	the	projector	with	the	filters	
removed.	Dust	may...

This	projector	uses	a	high-pressure	lamp	which	must	be	handled	carefully	and	properly.		
Improper	handling	may	result	in	accidents,	injury,	or	create	a	fire	hazard.
●	Lamp	 life	may	 differ	 from	lamp	 to	lamp	 and	according	 to	the	 environment	 of	use.	 There	 is	no	 guarantee	
of	 the	 same	 life	for	each	 lamp.	 Some	 lamps	 may	fail	or	terminate	 their	life	in	a	shorter	 period	of	time	
than	other	similar	lamps.
