[Reading	the	Table]
From	the	upper	table	on	this	page,	to	project	wide	images	on	a	150	screen,	install	at	about	4.1	m	from	the	front.
Also,	from	the	low er	table	we	can	see	that	about	2.1	m	are	required	from	the	projector’s	lens	center	to	the	upper	edge	
of	the	screen.	Use	this	to	see	whether	or	not	enough	height	can	be	provided	from	the	projector	to	the	ceiling	and	
for	installing	the	screen.	The	diagr am	shows	the	projection	distance	when	the	projector	is	installed	horiz ontally.	The	
projected	image	can	be	moved	up	and	down,	left	and	right	using	the	lens	shift	function.	(→	page	17)

Lens shifting range
This	projector	is	equipped	with	a	lens	shift	function	(→	page	17)	for	adjusting	the	image	position	using	dials.	Lens	
shifting	is	possible	within	the	range	shown	below.
NOTE:	
•	 In	case	lens	shifted	volume	exceeds	the	below	illustrated	range,	blur	and	shade	may	appear	around	ends	of	projected	image.
Legend:	V	“Vertical”	refers	to	the	screen	height	and	H	“Horiz ontal”	refers	to	the	screen	width.	The	lens	shift	range	is	
expressed	as	a	ratio	of	height	and	width,	respectively.

(Example)	When	using	to	project	on	a	150"	screen
[P502H/P452H]
According	to	the	“Table	of	screen	siz es	and	dimensions”	(→	page	71),	H	=	130.8"/332.1	cm,	V	=	73.6"/186.8	cm.
Adjustment	range	in	the	vertical	direction:	the	projected	image	can	be	mov ed	upwards	0.62	×	73.6"/186.8	cm	≈ 
45.3"/115	cm	(when	the	lens	is	at	the	center	position).	
Adjustment	range	in	the	horizontal	direction:	the	projected	image	can	be	mov ed	to	the	left	0.25	×	130.8"/332.1	cm	≈ 
32.7"/83	cm,	to	the	right	approximately	32.7"/83	cm.
[P502W/P452W]
According	to	the	“Table	of	screen	siz es	and	dimensions”	(→	page	71),	H	=	127.3"/323.1	cm,	V	=	79.5"/201.9	cm.
Adjustment	range	in	the	vertical	direction:	the	projected	image	can	be	mov ed	upwards	0.59	×	79.5"/201.9	cm	≈ 
46.9"/119	cm	(when	the	lens	is	at	the	center	position).	
Adjustment	range	in	the	horizontal	direction:	the	projected	image	can	be	mov ed	to	the	left	0.28	×	127.3"/323.1	cm	≈ 
35.4"/90	cm,	to	the	right	approximately	35.4"/90	cm.
*	 Figures	differ	by	several	%	because	the	calculation	is	approximate.
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	var y	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	har m	the	screen	image .
•	 Ensure	that	you	have	adequate	ventilation	around	your	projector	so	heat	can	dissipate.	Do	not	cov er	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	55)

❷ Making Connections
Connecting Your Computer
Computer	cables	and	HDMI	can	be	used	to	connect	to	a	computer.	The	HDMI	cable	is	not	enclosed	with	the	projector.	
Please	get	ready	a	suitable	cable	for	the	connection.

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.
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.
Cautions	when	using	a	DVI	signal
•	 When	the	computer	has	a	DVI	output	terminal,	use	a	commercially	available	conv erter	cable	to	connect	the	computer	
to	the	projector’s	HDMI	1	IN	or	HDMI	2	IN	terminal	(only	digital	video	signals	can	be	input).
HDMI 1 IN
HDMI 2 IN
AUDIO IN
NOTE:	When	Viewing	a	DVI	Digital	Signal
•	 Turn	off	the	power	of	the	computer	and	projector	before	connecting.
•	 When	a	video	deck	is	connected	via	a	scan	converter,	etc.,	the	display	may	not	be	correct	during	fast-forwarding	and	rewinding.
•	 Use	a	DVI-to-HDMI	cable	compliant	with	DDWG	(Digital	Display	Working	Group)	DVI	(Digital	Visual	Interface)	revision	1.0	stan-
dard.
	 The	cable	should	be	within	197"/5	m	long.
•	 Turn	off	the	projector	and	the	PC	before	connecting	the	DVI-to-HDMI	cable.
•	 To	project	a	DVI	digital	signal:	Connect	the	cables,	turn	the	projector	on,	then	select	the	HDMI	input.	Finally,	turn	on	your	PC.
	 Failure	to	do	so	may	not	activate	the	digital	output	of	the	graphics	card	resulting	in	no	picture	being	displayed.	Should	this	happen,	
restart	your	PC.
•	 Do	not	disconnect	the	DVI-to-HDMI	cable	while	the	projector	is	running.	If	the	signal	cable	has	been	disconnected	and	then	
reconnected,	an	image	may	not	be	correctly	displayed.	Should	this	happen,	restart	your	PC.
•	 The	COMPUTER	video	input	terminals	support	Windows	Plug	and	Play.
•	 A	Mac	signal	adapter	(commercially	available)	may	be	required	to	connect	a	Mac	computer.
5. Installation and Connections

Connecting an External Monitor
You	can	connect	a	separate,	exter nal	monitor	to	your	projector	to	simultaneously	view	on	a	monitor	the	computer

NOTE:
•	 The	AUDIO	OUT	mini	jack	does	not	support	Headphone	terminal.
•	 When	audio	equipment	is	connected,	the	projector	speaker	is	disabled.
•	 The	signal	output	from	the	MONITOR	OUT	(COMP.)	of	this	projector	is	for	projecting	image	on	exclusive	one	display.
•	 When	no	signal	is	applied	over	3	minutes	in	the	condition	of	projector	standby	when	NETWORK	STANDBY	is	set	in	the	Standby	
mode,	output	from	the	MONITOR	OUT	(COMP.)	or	AUDIO	OUT	terminal	will	be	stopped.	In	this	case	pull	out	the	computer	cable	
and	set	it	back	after	inputting	video	signal
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.	
	 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-	COMPUTER	IN	terminal	converted	signal	will	not	be	output	in	the	standby	mode	and	sleep	mode.
