    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:	
    •	 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	110)
    	 Use	the	computer’s	browser	to	display	the	projector’s	HTTP	server. 	(→	page	41)
    Step 3:	 Use	an	HTTP	server	to	set	the	wireless	LAN.	(→	page	44)
    	 Access	the	HTTP	 server	 function	 to	set	 [NETWORK	 SETTINGS]	→	[SETTINGS]	→	[WIRELESS]	→ 
    [EASY	CONNECTION]	, 	[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	94)

    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	[6000	 H]	at	time	 of	shipment	 on	M311X/M271X/M271W;	 the	time	
    to	clean	the	filters	is	set	to	[5000	H]	at	time	of	shipment	on	M361X/M311W.
    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.
     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.
    1.	 Push	the	button	to	release	the	filter	unit	and	pull	it	out. 	
    TIP:
    The	following	explanation	uses	filters	(fine-texture	sponge	and	
    coarse-texture	sponge)	attached	to	the	projector	at	the	time	of	
    purchase	as	an	example.
    After	replacing	with	filters	included	in	the	optional	lamp,	replace	the	
    words	“fine-texture	sponge	and	coarse-texture	sponge”	with	“ac-
    cordion	soft	and	honeycomb	hard”	respectively.
    2. Remove the filter cover.
      The filter cover is fixed at six separate mounting points.
     Bow  the  filter  cover  by  pushing  the  notch  slightly  until  it  re-
    leases. 
    3.	 Remove 	the 	four 	filters 	and 	use 	a 	vacuum 	cleaner 	to	
    vacuum	all	the	dust	inside.
      Get rid of dust in the sponge filter
    NOTE:	
    •	 Whenever	 you	vacuum	 the	filter,	 use	the	soft	 brush	 attachment	 to	
    vacuum.	This	is	to	avoid	damage	to	the	filter.
    •	 Do	not	wash	 the	filter	 with	water.	 Doing	so	can	 result	 in	filter	 clog-
    ging.

    7. Maintenance
     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.
     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.

    7. Maintenance
     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	99)
     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:
    	 NP15LP:	M311X/M271X/M271W
    	 NP16LP:	M361X/M311W
    	 The	replacement	 lamp	comes	 with	filters. 	While	 the	filters	 attached	 to	the	 projector	 at	the	 time	 of	purchase	 are	
    made	of	dark	 sponge	 material,	 the	filters	 included	 with	the	optional	 lamp	are	made	 of	non-woven	 white	material. 	
    There	is	no	difference	in	performance	between	these	two	types.
    •	 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.
