1. Introduction
 Introduction to the Projector
This	section	introduces	you	to	your	new	projector	and	describes	the	features	and	controls.
Congratulations on Your Purchase of the Projector
This	projector	 is	one	 of	the	 very	 best	projectors	 available	today.	The	 projector	 enables	you	to	project	 precise	 images	
up	to	500	 inches	 across	 (measured	 diagonally)	 from	your	PC	or	Macintosh	 computer	(desktop	or	notebook),	VCR,	
DVD	player,	or	document	camera.
You	 can	use	the	projector	 on	a	tabletop	 or	cart,	 you	can	 use	the	projector	 to	project	 images	 from	behind	 the	screen,	
and	the	projector	can	be	permanently	mounted	on	a	ceiling*1.	 The	remote	control	can	be	used	wirelessly.
*1	 Do	not	attempt	to	mount	the	projector	on	a	ceiling	yourself.
	 The	 projector	 must	be	installed	 by	qualified	 technicians	 in	order	 to	ensure	 proper	operation	 and	reduce	 the	risk	
of	bodily	injury.
	 In	 addition,	 the	ceiling	 must	be	strong	 enough	 to	support	 the	projector	 and	the	installation	 must	be	in	accordance	
with	any	local	building	codes. 	Please	consult	your	dealer	for	more	information.
 
Features you’ll enjoy:

	 The	PA722X/PA721X/PA622X/PA621X/PA672W/PA671W/PA572W/PA571W	 projectors	cover	input	signals	 up	to	
WUXGA	(1920	×	1200	dots)	thanks	to	the	Advanced	AccuBlend	function.
•	 Wide	range	of	optional	lenses	selectable	according	to	the	place	of	installation
	 This	 projector	 supports	5	types	 of	optional	 lenses,	providing	 a	selection	 of	lenses	 adapted	 to	a	variety	 of	places	
of	installation	and	projection	methods.
	 In	addition,	the	lenses	can	be	mounted	and	removed	in	one	touch.
	 Note	that	no	lens	is	mounted	upon	shipment	from	the	factory. 	Please	purchase	optional	lenses	separately.
•	 Lens	shift	function	for	easily	adjusting	the	position	of	the	projected	image
	 The	position	 of	the	 projected	 image	is	moved	 by	turning	 the	two	 dials	 on	the	 projector’s	 front,	one	for	the	 vertical	
direction,	one	for	the	horizontal	direction.
•	 360°	installation	angle	(tilt-free)
	 The	projector	can	be	installed	at	any	angle	(360°).
	 Note,	however,	that	the	 “fan	mode”	setting	must	be	changed	according	to	the	angle	of	installation.
	 Also,	the	projector	cannot	be	installed	tilted	to	the	left	or	right.
•	 Wide	range	of	input/output	connectors	(HDMI, 	DisplayPort,	BNC,	etc.)	and	built-in	monaural	speaker
	 The	 projector	 is	equipped 	with	 a	variety 	of	 input/output 	connectors: 	computer 	(analog),	 5-core	BNC,	 HDMI, 	
DisplayPort,	etc. 	(The	computer	(analog)	and	BNC	connectors	also	support	component	inputs.)
	 The	projector’s	HDMI	and	DisplayPort	input	connectors	support	HDCP.
	 The	projector	is	also	equipped	with	a	built-in	10W	monaural	speaker.
•	 High	picture	quality	processing	circuit
	 The	Reon-VX	video	processor	is	used	to	project	high	quality	images.
•	 Energy-saving	design	with	a	standby	power	consumption	of	0.2	watts
	 When	the	on-screen	 menu’s	standby	 mode	is	set	 to	“Power	 Saving”,	 the	power	 consumption	 in	the	 standby	 mode	 
						

							3
1. Introduction
is	0.2	watts.
•	 “Eco	mode”	for	low	power	consumption	and	 “Carbon	Meter”	display
	 The	projector	 is	equipped	 with	an	“eco	 mode” 	for	 reducing	 power	consumption	 during	use.	Furthermore,	 the	
power-saving	effect	when	the	eco	 mode	 is	set	 is	converted	 into	the	amount	 of	reductions	 of	CO2	emissions	 and	
this	is	indicated	 on	the	 confirmation	 message	displayed	 when	the	power	 is	turned	 off	and	 at	“Information” 	on	 the	
on-screen	menu	(CARBON	METER).
•	 Maximum	 lamp	replacement	 time	of	4000	 hours	 (3000	hours	 in	Normal	 mode)	and	no	need	 to	clean	 the	
filters
	 When	used	in	the	eco	mode,	the	lamp	replacement	time*	is	extended	to	a	maximum	of	4000	hours.
	 *	This	time	is	not	guaranteed.
	 Furthermore,	 this	projector	 uses	large	 2-layer	 filters.	When	 these	filters	are	replaced	 with	new	 ones	 when	 changing	
the	lamp,	there	is	no	need	for	regular	filter	cleaning.
•	 Seamless	switch	function	for	smoother	screen	changes	when	switching	the	signal
	 When	 the	input	 connector	 is	switched,	 the	image	 displayed	 before	switching	 is	held	 so	that	 that	the	new	 image	
can	be	switched	to	without	a	break	due	to	absence	of	a	signal.
•	 Simultaneous	display	of	2	images	(PIP/PICTURE	BY	PICTURE)
	 Two	images	can	be	projected	simultaneously	with	a	single	projector.
	 There	 are	two	 types	 of	layouts	 for	the	 two	 images: 	“picture-in-picture” 	in	 which	 a	sub-picture	 is	displayed	 on	the	
main	picture,	and	 “picture-by-picture” 	in	which	the	main	and	sub	pictures	are	displayed	next	to	each	other.
•	 Security	function	for	preventing	unauthorized	use
	 This	projector	is	equipped	with	the	following	security	functions:
-	 Password	security:	When	 a	password	 is	set	 in	the	 on-screen	 menu,	a	screen	 to	input	 the	password	 appears	
when	the	projector’s	power	is	turned	on.
-	 Theft	prevention	lock: 	A	security	cable	compatible	with	Kensington	locks	can	be	connected	to	the	projector.
-	 Security	bar:	The	projector	has	a	mechanism	allowing	a	regular	security	cable	(or	wire)	to	be	installed.
•	 Wired/wireless	LAN	compatibility	(wireless	LAN	unit	sold	separately)
	 The	 projector	 is	equipped	 with	a	LAN	 port	(RJ-45)	 for	connection	 to	a	wired	 LAN	for	transferring	 images	from	a	
computer	to	the	projector,	controlling	the	projector	from	a	computer,	etc.
	 Furthermore,	 the	projector	 can	be	used	 in	a	wireless	 LAN	by	mounting	 the	separately	 sold	wireless	 LAN	unit	
(NP02LM).
•	 Convenient	utility	software	(User	Supportware)	provided	as	standard
	 Seven	 utility	software	 programs	 (Virtual	Remote	 Tool,	Image	 Express	 Utility	Lite,	Desktop	 Control	Utility	1.0,	PC	
Control	Utility	Pro	4)	are	provided	on	the	included	NEC	Projector	CD-ROM.
•	 LAN-compatible	viewer	function
	 Still	 and	moving	 images	 in	shared	 folders	on	a	computer	 connected	 by	wired	 or	wireless	 LAN	can	be	projected	
with	the	projector’s	viewer.
-	 The	viewer	supports	the	 Windows	Media	Player	11’s	“media	sharing”	function.
•	 CRESTRON	ROOMVIEW	compatibility
	 The	projector	 supports	CRESTRON	 ROOMVIEW,	 allowing	multiple	devices	connected	 in	the	 network	 to	be	 managed 	
and	controlled	from	a	computer.
