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	 (200	or	300	 inches	 depending	 on	the	 optional	 lens)	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:
•	 DLP® projector with high resolution and high brightness 
	 High	resolution	display	–	WUXGA	(1920	×	1200)	native	resolution	(16:10)
•	 Wide	range	of	optional	lenses	selectable	according	to	the	place	of	installation
	 This	projector	 supports	6	types	 of	optional	 lenses,	providing	 a	selection	 of	lenses	 adapted	 for	a	variety	 of	installation 	
requirements.
	 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.
•	 Dual	Lamp	system
	 Two	lamp	system	offers	increased	lamp	life	and	energy	savings	along	with	redundancy.
•	 Double	stackable	for	built	in	redundancy	and	high	light	output	requirements
	 Double	stacking	projectors	increase	the	brightness	and	visibility.
•	 Powered	Lens	Shift,	Zoom,	and	Focus	offer	installation	flexibility
	 Powered	 Horizontal	and	Vertical	 lens	shift	provides	 the	ability	 to	project	 from	off	center	 screen	 installations. 	Powered 	
zoom	and	focus	provide	quick	and	easy	adjustment.
•	 Two	types	of	color	wheels	(6-segment	white)	and	(6-segment	color)	interchangeable
	 The	projector	 is	shipped	 with	the	6-segment	 white	color	wheel	 installed. 	You	 can	replace	 it	with	 the	included	
6-segment	color	wheel	to	create	images	with	more	brilliant	colors	to	match	the	source.
•	 Wide	range	of	input/output	connectors	(HDMI, 	DisplayPort,	BNC,	etc.)	
	 The	 projector	 is	equipped	 with	a	variety	 of	input/output	 connectors:	computer	 (analog),	5	BNC,	 HDMI,	 DisplayPort,	
Video,	S-Video,	etc. 	(The	computer	(analog)	and	BNC	connectors	also	support	component	inputs.)
	 The	projector’s	HDMI	and	DisplayPort	input	connectors	support	HDCP.
•	 Slot	for	optional	board
	 The	projector	has	a	slot	for	the	optional	board	(SB-01HC	or	other	NEC’s	interface	boards).
•	 High	picture	quality	processing	circuit
	 IDT	HQV	processing	technology	is	used	to	project	high	quality	images.
•	 Energy-saving	design	with	a	standby	power	consumption	of	0.4	 Watts	or	less
	 When	the	on-screen	 menu’s	standby	 mode	is	set	 to	“Power	 Saving”,	 the	power	 consumption	 in	the	 standby	 mode	
is	0.2	W	(100-120	 V	AC)/	0.4W	(200-240V	AC).

1. Introduction
•	 “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).
•	 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	projector	 can	write	
the	new	image	without	going	to	black.
•	 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.
•	 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
	 Three	 utility	software	 programs	 (Image	Express	 Utility	2.0,	PC	Control	 Utility	Pro	4,	Image	 Express	 Utility	2	for	 Mac) 	
are	provided	 on	the	 included	 NEC	Projector	 CD-ROM.	Two	 more	 utility	software	 programs	 can	be	downloaded	
from	our	website: 	Virtual	Remote	 Tool	and	Viewer	PPT	Converter	3.0.
•	 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.
