8. Maintenance
This	section	describes	the	simple	maintenance	procedures	you	should	follow	to	clean	the	filters,	the	projection	window ,	
the	cabinet,	and	to	replace	the	lamp	and	the	filters.
❶ Cleaning the Filters
Filters	are	fixed	at	two	positions	on	this	projector.
Intake	vent	filter:
At	the	bottom	of	control	panel.
Prevent	the	projector	inside	from	dust	and	dirt	accumulation.
Color	wheel	filter:	
Fixed	inside	the	lamp	cover.	
Prevent	the	color	wheel	from	dust	and	dirt	accumulation.
In	this	manual,	call	the	intake	vent	filter	“Filter	(A)”	and	the	color	wheel	filter	“Filter	(B)”.
If	dust	and	dirt	accumulates	on	the	Filter	(A),	it	may	cause	of	trouble	by	overheat.	Clean	it	periodically .	Cleaning	is	not	
necessary	for	the	Filter	(B).
 WARNING
•	 Do	not	use	a	spray	containing	flammable	gas	to	get	rid	of	accumulated	dust	and	dirt	on	the	filters.	It	may	cause	
of	fire.
NOTE:	The	message	for	filter	cleaning	will	be	displayed	for	one	minute	after	the	projector	is	turned	on.	When	the	message	is	dis-
played,	clean	the	filter.
To	cancel	the	message,	press	any	button	on	the	projector	cabinet	or	the	remote	control.
 CAUTION
•	 Before	cleaning	the	filter,	turn	off	the	projector	and	unplug	the	pow er	cord	first.	Wait	and	make	sure	until	the	
unit	has	cooled	down	completely.	Removing	the	filter	co ver	when	the	unit	is	r unning	could	result	in	b urns.
Turn	off	the	projector	and	unplug	the	power	cord	before	cleaning	the	cabinet	or	replacing	the	lamp.

1. Turn off the power supply and pull out the plug from the wall 
outlet.
2. Pinch the knob at the bottom of the filter case and pull it out.
•	 If	you	put	the	projector	upside	down	for	cleaning	as	the	illustra-
tion, please lay a mat as a cloth for protecting the cabinet top 
from damage.

4.	 Vacuum	all	the	dust	on	the	Filter	(A)	and	the	filter	case.
•	 Get	rid	of	dust	accumulated	on	the	intake	vent	on	the	projector.
•	 Make	sure	to	use	a	br
ush	ad aptor	on	the	vac uum	cl eaner.	Ne ver	
apply the vacuum hose or the hard nozzle directly on the filter 
and filter case without fixing on a brush adaptor.
•	 Pay	enough	attention	not	to	damage	the	filter	(A).
•	 Do	not	wash	the	filters	with	soap	and	water.	Soap	and	water	will	
damage the filter membrane.

❷ Cleaning the Lens
•	 Turn	off	the	projector	before	cleaning.
•	 Do	not	scratch	or	mar	the	projection	window	as	it	is	made	of	glass.
•	 Use	a	blower	or	lens	paper	to	clean	the	projection	window,	and	be	careful	not	to	scratch	or	mar	the	glass	surface .
•	 Never	use	alcohol	or	glass	lens	cleaner	as	doing	so	will	cause	of	damage	to	the	plastic	lens	surface.
 WARNING

❸ Cleaning the Cabinet
Turn	off	the	projector,	and	unplug	the	projector	before	cleaning.
•	 Use	a	dry	soft	cloth	to	wipe	dust	off	the	cabinet.
	 If	heavily	soiled,	use	a	mild	detergent.	
•	 Never	use	strong	detergents	or	solvents	such	as	alcohol	or	thinner.	
•	 For	cleaning	the	vents	or	the	speaker,	use	a	vacuum	cleaner	with	a	brush	attachment.	Do	not	apply	the	vacuum	
hose	or	the	nozzle	adaptor	directly	onto	the	vents	and	speaker.
Vacuum the dust off the vents.
•	 Clogged	vents	may	cause	a	rise	in	the	internal	temperature	of	the	projector,	resulting	in	malfunction.
•	 Do	not	scratch	or	hit	the	cabinet	with	your	fingers	or	any	hard	objects
•	 Contact	your	dealer	for	cleaning	the	inside	of	the	projector.
NOTE:	Do	not	apply	volatile	agent	such	as	insecticide	on	the	cabinet,	the	projection	window,	or	the	screen.	Do	not	leave	a	rubber	
or	vinyl	product	in	prolonged	contact	with	it.	Otherwise	the	surface	finish	will	be	deteriorated	or	the	coating	may	be	stripped	off.

❹ Replacing the Lamp and the Filters
When	the	lamp	reaches	the	end	of	its	life,	the	LAMP	indicator	in	the	cabinet	will	blink	red	and	the	message	“THE	
LAMP	HAS	REACHED	THE	END	OF	ITS	USABLE	LIFE.	PLEASE	REPLACE	THE	LAMP	AND	FILTER. ”	will	appear	
(*).	Even	though	the	lamp	may	still	be	working,	replace	the	lamp	to	maintain	the	optimal	projector	perfor mance.	After	
replacing	the	lamp,	be	sure	to	clear	the	lamp	hour	meter.	(→	page	68)
 CAUTION
•	 DO	NOT	TOUCH	THE	LAMP	immediately	after	it	has	been	used.	It	will	be	extremely	hot.	Turn	the	projector	off	
and	then	disconnect	the	power	cord.	Allow	at	least	one	hour	f or	the	lamp	to	cool	bef ore	handling.
•	 Use	the	specified	lamp	for	safety	and	performance.	
	 To	order	the	replacement	lamp,	specify	your	lamp	type.
	 Replacement	lamp:
	 NP39LP:	P502H/P502W
	 NP38LP:	P452H/P452W
	 The	replacement	lamp	comes	with	filters.	Replace	the	lamp	and	the	filters	(A)	(B)	at	the	same	time .
•	 DO	NOT	REMOVE	ANY	SCREWS	except	one	lamp	cover	screw	and	three	lamp	housing	screws .	You	could	receive	
an	electric	shock.
•	 Do	not	break	the	glass	on	the	lamp	housing.
	 Keep	finger	prints	off	the	glass	surface	on	the	lamp	housing.	Leaving	finger	prints	on	the	glass	surface	might	cause	
an	unwanted	shadow	and	poor	picture	quality.
•	 The	projector	will	turn	off	and	go	into	standby	mode	when	you	continue	to	use	the	projector	for	another	100	hours	
after	the	lamp	has	reached	the	end	of	its	life.	If	this	happens,	be	sure	to	replace	the	lamp.	If	you	continue	to	use	
the	lamp	after	the	lamp	reaches	the	end	of	its	life ,	the	lamp	bulb	may	shatter,	and	pieces	of	glass	may	be	scattered	
in	the	lamp	case.	Do	not	touch	them	as	the	pieces	of	glass	may	cause	injury .	If	this	happens,	contact	your	NEC	
dealer	for	lamp	replacement.
*NOTE:	This	message	will	be	displayed	under	the	following	conditions:
•	 for	one	minute	after	the	projector	has	been	powered	on
