7. Maintenance
❷ Cleaning the Lens
•	 Turn	off	the	projector	before	cleaning.
•	 The	projector	has	a	plastic	lens.	Use	a	commercially	available	plastic	lens	cleaner.
•	 Do	not	scratch	or	mar	the	lens	surface	as	a	plastic	lens	is	easily	scratched.
•	 Never	use	alcohol	or	glass	lens	cleaner	as	doing	so	will	cause	damage	to	the	plastic	lens	surface.
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. 	
•	 When	cleaning	the	ventilation	 slits	or	the	 speaker	 using	a	vacuum	 cleaner,	 do	not	 force	 the	brush	 of	the	 vacuum	
cleaner	into	the	slits	of	the	cabinet.
Vacuum the dust off the ventilation slits.
•	 Clogged	ventilation	slits	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	lens,	 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	 performance. 	After	
replacing	the	lamp,	be	sure	to	clear	the	lamp	hour	meter. 	(→	page	117)
 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	for	the	lamp	to	cool	before	handling.
•	 Use	the	specified	lamp	for	safety	and	performance.
	 To	order	the	replacement	lamp,	specify	your	lamp	type.
	 Replacement	lamp:
	 NP23LP
	 The	replacement	lamp	comes	with	filters. 	
•	 DO	NOT	REMOVE	 ANY	SCREWS	 except	one	lamp	 cover	 screw	 and	two	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
•	 when	the		(POWER)	button	on	the	projector	cabinet	or	the	POWER	OFF	button	on	the	remote	control	is	pressed
To	turn	off	the	message,	press	any	button	on	the	projector	cabinet	or	the	remote	control.
Optional	lamp	and	tools	needed	for	replacement:
•	 Phillips	screwdriver	(plus-head)
•	 Replacement	lamp

7. Maintenance
This	completes	the	lamp	replacement.
Go	on	to	the	filter	replacement.
NOTE:	When	you	continue	 to	use	 the	projector	 for	another	 100	hours	 after	the	lamp	 has	reached	 the	end	 of	its	 life,	 the	projector	
cannot	turn	on	and	the	menu	is	not	displayed.
If	this	happens,	press	the	HELP	button	on	the	remote	control	for	10	seconds	to	reset	the	lamp	clock	back	to	zero.
When	the	lamp	time	clock	is	reset	to	zero,	the	LAMP	indicator	goes	out.
	
4.	 Reattach	the	lamp	cover.
(1)	Slide	the	lamp	cover	back	until	it	snaps	into	place.
(2)	Tighten	the	screw	to	secure	the	lamp	cover.
	 •	Be	sure	to	tighten	the	screw.
3.	 Install	a	new	lamp	housing.
(1)	Insert	a	new	lamp	housing	until	the	lamp	housing	is	plugged	into	the	socket. 	
(2)	Push	the	top	center	of	the	lamp	housing	to	secure	it.
(3)	Secure	it	in	place	with	the	two	screws.

7. Maintenance
To	replace	the	filters:
Four	filters	are	packaged	with	the	replacement	lamp.
Honeycomb	filter	(coarse	mesh):	Large	and	small	sizes	(attached	to	the	outside	of	the	filter	unit)
Accordion	filter	(fine	mesh):	Large	and	small	sizes	(attached	to	the	inside	of	the	filter	unit)
NOTE:	
•	 Replace	all	four	filters	at	the	same	time.
•	 Before	replacing	the	filters,	wipe	off	dust	and	dirt	from	the	projector	cabinet.	
•	 The	projector	is	precision	equipment.	Keep	out	dust	and	dirt	during	filter	replacement.
•	 Do	not	wash	the	filters	with	soap	and	water.	Soap	and	water	will	damage	the	filter	membrane.	
•	 Put	filters	into	place.	Incorrect	attachment	of	a	filter	may	cause	dust	and	dirt	to	get	into	the	inside	of	the	projector.	
Before	replacing	the	filters,	replace	the	lamp. 	(→	page	160)
1.	 Push	up	the	buttons	on	the	left	and	right	to	release	the	filter	unit	and	pull	it	out.

5.	 Attach	four	new	filters	to	the	filter	unit.
(1)	Insert	 the	left	end	 of	each	 hard	honeycomb	 filter	(large	 and	small)	 first	and	 then	 the	right	 end	of	each	 hard	
honeycomb filter to the filter unit.
	 •		The	large	filter	cannot	be	fitted	if	its	right	end	is	inserted.
(2) Turn the filter unit over.
	 •		 Attach	 the	two	 soft	 accordion	 filters	(large	 and	small). 	Each	 accordion	 filter	has	a	slit	 on	it.	Align	 the	slit	with	
each protrusion of the filter unit.
6.	 Put	the	filter	unit	back	to	the	projector	cabinet.
	 Make	sure	that	the	filter	unit	is	placed	in	the	correct	orientation.
7.	 Put	the	filter	cover	back	to	the	projector	cabinet.
	 Insert	 two	catches	 of	the	 top	side	 of	the	 filter	 cover	 into	the	groove	 of	the	 cabinet,	 and	push	 the	buttons	 on	the	 left	
and right to close the filter cover.

❷ Using the Computer Cable (VGA) to Operate the Projector 
(Virtual Remote Tool)
Using	 the	utility	 software	 “Virtual	Remote	 Tool”,	Virtual	 Remote	 screen	(or	toolbar)	 can	be	displayed	 on	your	 computer	
screen.
This	 will	help	 you	perform	 operations	 such	as	projector’s	 power	on	or	off	 and	 signal	 selection	 via	the	 computer	 cable	
(VGA),	serial	cable,	 or	LAN	 connection. 	Only	 via	serial	 or	LAN	 connection	 it	is	 also	 used	 to	send	 an	image	 to	the	
projector	 and	register	 it	as	 the	 logo	 data	 of	the	 projector. 	After	 registering	 it,	you	 can	 lock	 the	logo	 to	prevent	 it	from	
changing.
Control	Functions
Power	 On/Off,	 signal	selection,	 picture	freeze,	 picture	mute,	audio	mute,	 Logo	transfer	 to	the	 projector,	 and	remote	
control	operation	on	your	PC.
Virtual	Remote	screen
Remote	Control	 WindowToolbar
This	section	provides	an	outline	of	preparation	for	use	of	 Virtual	Remote	Tool.
For	information	on	how	to	use	 Virtual	Remote	Tool,	see	Help	of	 Virtual	Remote	Tool.	(→	page	172)
TIP:
•	 Virtual	Remote	Tool	can	be	used	with	a	LAN	and	a	serial	connection.
•	 For	update	information	on	Virtual	Remote	Tool,	visit	our	website:	
	 http://www.nec-display.com/dl/en/index.html
NOTE:
•	 When	 [COMPUTER]	 is	selected	 from	your	source	 selection,	 the	Virtual	 Remote	 screen	or	the	 toolbar	 will	be	displayed	 as	well	 as	
your	computer	screen.
•	 Use	 the	supplied	 computer	 cable	(VGA)	 to	connect	 the	COMPUTER	 IN	connector	 directly	with	the	monitor	 output	connector	 of	
the	computer	to	use	Virtual	Remote	Tool.
	 Using	a	switcher	or	other	cables	than	the	supplied	computer	cable	(VGA) 	may	cause	failure	in	signal	communication.
	 VGA	cable	connector:
	 Pin	Nos.	12	and	15	are	required	for	DDC/CI.
•	 Virtual	Remote	Tool	may	not	work	depending	on	your	computer’s	specifications	and	version	of	graphic	adapters	or	drivers.
•	 Logo	data	(graphics)	that	can	be	sent	to	the	projector	with	Virtual	Remote	Tool	has	the	following	restrictions:
	 (Only	via	serial	or	LAN	connection)
-	 File	size:	Less	than	1	MB	
-	 Image	size	(resolution):	
	 P501X/P451X/PE501X:	Horizontal	1024	dots	×	vertical	768	dots	or	less
	 P451W/P401W:	Horizontal	1280	dots	×	vertical	800	dots	or	less
-	 Number	of	colors:	256	colors	or	less
TIP:
•	 The	projector’s	 COMPUTER	 IN	connector	 supports	DDC/CI	(Display	 Data	Channel	 Command	 Interface).	DDC/CI	is	a	standard	
interface	for	bidirectional	communication	between	display/projector	and	computer.
