WARNING
*	 Installing	 your	projector	 on	the	 ceiling	 must	be	done	 by	a	qualified	 technician. 	Contact	 your	NEC	 dealer	 for	more	
information.
*	 Do	not	attempt	to	install	the	projector	yourself.
•	 Only	 use	your	 projector	 on	a	solid,	 level	surface. 	If	 the	 projector	 falls	to	the	 ground,	 you	can	 be	injured	 and	the	
projector	severely	damaged.
•	 Do	 not	use	 the	projector	 where	temperatures	 vary	greatly. 	The	 projector	 must	be	used	 at	temperatures	 between	
41°F	(5°C)	and	104°F	(40°C)	(Eco	mode	selected	automatically	at	95°F	to	104°F/35°C	to	40°C).
•	 Do	not	expose	the	projector	to	moisture,	dust,	or	smoke. 	This	will	harm	the	screen	image.
•	 Ensure	 that	you	have	 adequate	 ventilation	 around	your	projector	 so	heat	 can	dissipate. 	Do	 not	 cover	 the	vents	 on	
the	side	or	the	front	of	the	projector.
Reflecting the Image
Using	 a	mirror	 to	reflect	 your	projector’s	 image	enables	 you	to	enjoy	 a	much	 larger	 image	 when	a	smaller	 space	is	
required. 	Contact	 your	NEC	 dealer	 if	you	 need	 a	mirror	 system. 	If	 you’re	 using	a	mirror	 system	 and	your	 image	 is	
inverted,	 use	the	MENU	 and	▲▼◀▶	buttons	 on	your	 projector	 cabinet	or	your	 remote	 control	to	correct	 the	orienta-
tion. 	(→	page	100)

available distribution amplifier if 
connecting a signal cable longer 
than the cable supplied.
NOTE:	For 	Mac, 	use 	a 	commercially	
available	 pin	adapter	 (not	sup-
plied) 	to 	connect 	to 	your 	Mac’s	
video	port.

❷ Making Connections
NOTE:	 When	using	with	a	notebook	 PC,	be	sure	 to	connect	 the	projector	 and	notebook	 PC	while	 the	projector	 is	in	 standby	 mode	
and	before	turning	on	the	power	to	the	notebook	PC.
In	most	cases	the	output	signal	from	the	notebook	PC	is	not	turned	on	unless	connected	to	the	projector	before	being	powered	up.
*	 If	the	screen	 goes	blank	 while	using	 your	remote	 control,	 it	may	 be	the	 result	 of	the	 computer’s	 screen-saver	 or	power	 manage-
ment	software.
Enabling the computer’s external display
Displaying	an	image	on	the	notebook	PC’s	screen	does	not	necessarily	mean	it	outputs	a	signal	to	the	projector.
When	using	a	PC	compatible	laptop,	a	combination	of	function	keys	will	enable/disable	the	external	display.
Usually,	 the	combination	 of	the	 “Fn” 	key	 along	 with	one	of	the	 12	function	 keys	gets	the	external	 display	to	come	 on	
or	off. 	For	 example,	 NEC	laptops	 use	Fn	+	F3,	 while	 Dell	laptops	 use	Fn	+	F8	 key	 combinations	 to	toggle	 through	
external	display	selections.

NOTE:	The	projector	is	not	compatible	with	video	decoded	outputs	of	the	NEC	ISS-6020	switcher.
NOTE:	An	image	may	not	be	displayed	correctly	when	a	Video	source	is	played	back	via	a	commercially	available	scan	converter.	
This	is	because	the	projector	will	process	a	video	signal	as	a	computer	signal	at	the	default	setting.	In	that	case,	do	the	following.
*	 When	an	image	is	displayed	with	the	lower	and	upper	black	portion	of	the	screen	or	a	dark	image	is	not	displayed	correctly:
	 Project	an	image	to	fill	the	screen	and	then	press	the	AUTO	ADJ.	button	on	the	remote	control	or	the	projector	cabinet.

6. Installation and Connections
Connecting an External Monitor
You	can	connect	 a	separate,	 external	monitor	to	your	 projector	 to	simultaneously	 view	on	a	monitor	 the	computer	
analog	image	you’re	projecting.
NOTE:
•	 The	AUDIO	OUT	mini	jack	does	not	support	Headphone	terminal.
•	 Daisy	chain	connection	is	not	possible.
•	 When	audio	equipment	is	connected,	the	projector	speaker	is	disabled.
Monitor	out	and	sleep	mode:
•	 The	MONITOR	OUT	(COMP.)	terminal	will	not	work	when	[NORMAL]	is	selected	for	[STANDBY	MODE].
	 The	MONITOR	OUT	(COMP.)	terminal	will	work	only	in	the	sleep	mode.
	 Applying	 a	signal	 from	the	COMPUTER	 IN	terminal	 will	put	 the	projector	 in	the	 sleep	 mode,	 which	allows	 you	to	use	
the	 MONITOR	 OUT(COMP.)	 terminal	and	the	AUDIO	 OUT	mini	jack.	Sound	 from	the	MIC	 input	 jack	will	be	output	
to	the	AUDIO	OUT	mini	jack.
	 The	sleep	mode	is	one	of	the	standby	modes. 	The	sleep	mode	cannot	be	selected	from	the	menu.
•	 In	the	network	standby	mode,		sound	for	the	last	viewed	computer	or	video	source	will	be	heard.
		 BNC-to-	D-SUB	converted	signal	will	not	be	output	in	the	standby	mode	and	sleep	mode.

TIP:	For	users	of	audio	video	equipment	with	an	HDMI	terminal:
Select	“Enhanced”	rather	than	“Normal”	if	HDMI	output	is	switchable	between	“Enhanced”	and	“Normal”.
This	will	provide	improved	image	contrast	and	more	detailed	dark	areas.

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	109).

6. Installation and Connections
Connecting to a Wireless LAN
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	128)
	 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]	→ 
[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	110)
Select	[DISABLE],	[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).
