6. Installation and Connections
Connecting to a Wired LAN
The	projector	comes	standard	with	a	LAN	port	(RJ-45)	which	provides	a	LAN	connection	using	a	LAN	cable.	
To	use	 a	LAN	 connection,	 you	are	required	 to	set	 the	 LAN	 on	the	 projector	 menu.		Select	 [SETUP]	→	[WIRED	 LAN].	
(→	page	106).

6. Installation and Connections
Connecting to a Wireless LAN (Optional: NP02LM series)
The	USB	 Wireless	 LAN	Unit	also	 provides	 a	wireless	 LAN	connection. 	To	 use	 a	wireless	 LAN	connection,	 you	are	
required	to	assign	an	IP	address	to	the	projector.
Important:
•	 If	 you	use	 the	projector	 with	the	USB	 Wireless	 LAN	Unit	in	the	 area	 where	 the	use	 of	wireless	 LAN	equipment	 is	
prohibited,	remove	the	USB	 Wireless	LAN	Unit	from	the	projector.
•	 Buy	the	appropriate	USB	 Wireless	LAN	Unit	for	your	country	or	area.
NOTE:	
•	 When	the	projector	 is	turned	 on	with	 the	optional	 wireless	 LAN	unit	inserted,	 the	indicator	 will	light	 up	blue	 and	the	green	 LED	
on	the	USB	Wireless	LAN	Unit	flashes	to	show	that	the	USB	Wireless	LAN	Unit	is	working.
•	 Your	computer’s	wireless	LAN	adapter	(or	unit)	must	be	complied	with	Wi-Fi	(IEEE802.11b/g/n)	standard.
Flow of Setting Wireless LAN
Step 1: Attach the USB Wireless LAN Unit to the projector.
Step 2:	 Connect	the	computer	to	the	projector	via	wired	LAN. 	(→	page	123)
	 Use	the	computer’s	browser	to	display	the	projector’s	HTTP	server. 	(→	page	45)
Step 3:	 Use	an	HTTP	server	to	set	the	wireless	LAN.	(→	page	48)
	 Access	the	HTTP	 server	 function	 to	set	 [NETWORK	 SETTINGS]	→	[SETTINGS]	→	[WIRELESS]	→ 
[EASY	CONNECTION], 	[SIMPLE	ACCESS	POINT], 	[PROFILE1]	or	[PROFILE2].
NOTE:	
•	 To	use	the	HTTP	server	function,	the	projector	must	be	connected	to	a	network.
	 First	use	the	wired	LAN	to	connect	the	projector	to	a	network	and	then	use	the	HTTP	server	to	set	the	wireless	LAN.
•	 After	setting	the	wireless	LAN	by	using	the	HTTP	server,	set	[NETWORK	SETTINGS]	→	[SETTINGS]	→	[WIRED]	→	[DISABLE]
When	switching	to	set	on	the	projector	after	connecting	to	the	wireless	LAN:
Use	the	menu	to	set	the	wireless	LAN	connection	for	the	projector. 	
(→	page	107)
Select	[DISABLE],	[EASY	CONNECTION]	,	[PROFILE1]	or	[PROFILE2]	you	set	from	the	HTTP	server.
Attaching the USB Wireless LAN Unit
NOTE:
•	 The	USB	Wireless	 LAN	Unit	must	 be	inserted	 into	the	USB	 Wireless	 LAN	Unit	port	in	the	 correct	 direction.	 It	cannot	 be	inserted	
in	the	 reverse	 direction.	 If	the	 USB	 Wireless	 LAN	Unit	is	inserted	 in	the	 reverse	 direction	 with	excessive	 force	applied,	 the	USB	
port	may	break.
•	 Before	 touching	the 	USB 	Wireless 	LAN 	Unit,	 touch	 a	metallic 	object	 (such	as	a 	door 	knob 	or 	aluminum 	window	 frame)	to	discharge	
the	static	electricity	from	your	body.
•	 Always	 insert	or	remove	 the	USB	 Wireless	 LAN	unit	when	 the	main	 power	 is	turned	 off.	Failure	 to	do	 so	may	 cause	 projector	
malfunction	 or	damage	 to	the	 USB	 wireless	 LAN	unit.	 If	the	 projector	 will	not	work	 correctly,	 turn	off	the	 projector,	 disconnect	
the	power	cord,	and	then	connect	it	again.
•	 Do	not	insert	 other	USB	devices	 into	the	USB	 Wireless	 LAN	unit	port.	 Do	not	 insert	 the	USB	 Wireless	 LAN	unit	into	the	USB-B	
port	(Type	B).

3.	 Slowly	insert	the	USB	 Wireless	 LAN	Unit	into	the	USB	 (LAN)	
port.
 Remove the cap from the USB Wireless LAN Unit, and then insert 
it with the surface (side of indicator) facing outward. Keep the cap 
for later use.
NOTE:	Do	not	force	to	insert	the	USB	Wireless	LAN	Unit.
4.	 Put	the	USB	(LAN)	port	cover	back	into	place.
	 Insert	 the	catch	 of	the	 USB	 (LAN)	 port	cover	 into	the	groove	 of	the	
projector  cabinet,  and  then  tighten  the  screw  to  secure  the  port 
cover.
To	 remove	 the	USB	 Wireless	 LAN	Unit,	 disconnect	 the	power	 cord	
and	use	the	above	procedure.
NOTE:	
•	 The	green	LED	on	the	 USB	 Wireless	 LAN	Unit	flashes	 to	show	 that	Wireless	
LAN	 Unit	is	working.	 If	the	 USB	 Wireless	 LAN	Unit	is	incorrectly	 attached,	
the	blue	LED	will	not	flash.
•	 Do	not	press	 the	button	 on	the	 USB	 Wireless	 LAN	Unit.	 The	button	 will	not

This	section 	describes 	the 	simple 	maintenance 	procedures 	you 	should 	follow 	to 	clean 	the 	lens, 	the 	cabinet, 	and 	to	
replace	the	lamp.
❶ 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.
❷ 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	vents	 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 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	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.

❸ Replacing the Lamp
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.” 	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	113)
 WARNING
•	 Do	not	spray	 flammable	 gas	to	get	 rid	of	dust	 and	dirt	that	 accumulate	 in	the	 lens. 	Doing	 so	could	 cause	 a	
fire.
 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:
	 NP30LP:	M352WS/M332XS
	 NP28LP:	M302WS
•	 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
•	 when	the		(POWER)	button	on	the	projector	cabinet	or	the	STANDBY	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
