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	DLP®	projector	is 	one 	of 	the 	very 	best 	projectors 	available 	today. 	The 	projector 	enables 	you 	to 	project 	precise 	
images	up	to 	300 	inches 	(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 	projecto r 	and 	the 	installation 	must 	be 	in 	accordance 	with 	any 	
local	building	codes.	Please	consult	your	dealer	for	more	information.
Features you'll enjoy:
•	Quick start & Quick Power Off
	 7	seconds	after	turning	on	the	power,	the	projector	is	ready	to	 display 	 PC 	 or 	 video 	 images.
	 The	projector 	can 	be 	put 	away 	immediately 	after 	the 	projector	is 	powered 	down. 	No 	cool 	down 	period 	is 	required 	
after	the	projector	is	turned	off	from	the	remote	control	or	cabinet	control	panel.
•	Direct Power Off
	 The	projecto r 	has 	a 	feature 	called 	“Direct 	Power 	Off”. 	This 	feature 	allows 	the 	projector 	to 	be 	turned 	off 	(even 	when 	
projecting	an	image)	by	disconnecting	the	AC	power	supply.
	 To	turn	off 	the 	AC 	power 	supply 	when 	the 	projector 	is 	powere d 	on, 	use 	a 	power 	strip 	equipped 	with 	a 	switch 	and 	
a	breaker.
•	Less than 0.4W in standby condition with energy saving technology
	 Selecting	[POWER-SAVING] 	for 	[STANDBY 	MODE] 	from 	the 	menu 	can 	put 	the 	projector 	in 	power-saving 	mode 	
that	consumes	only	0.3W	(100-130V	AC)/0.4W	(200-240V	AC).
•	Carbon Meter
	 This	feature 	will 	show 	energy -saving 	effect 	in 	terms 	of 	CO2	emission	reduction 	(kg) 	when 	the 	projector’s 	[ECO 	
MODE]	is	set	to	[ON].
	 The	amount	of 	CO2	emission	reduction 	will 	be 	displa yed 	in 	the 	confirmation 	message 	at 	the 	time 	of 	power-off 	and 	
in	the	INFO	of	the	on-screen	menu.
•	7W built-in speaker for an integrated audio solution
	 Powerful	7	watt	speaker	provides	volume	need	for	large	rooms.
•	HDMI input port provides digital signal (VE281X/VE282X/VE281/VE282 only)
	 The	HDMI	input	provides	HDCP	compatible	digital	signals.	The	HDMI	input	also	supports	audio	signal.
•	DLP® projector with high resolution and high brightness 
	 High	resolution 	display 	- 	up 	to 	UXGA 	compatible, 	XGA 	(VE280X/VE281X/VE282X)/ 	SVGA 	(VE280/VE281/VE282)	
native	resolution.
•	AUTO POWER ON and AUTO POWER OFF features
	 The	DIRECT 	POWER 	ON, 	AUTO 	POWER 	ON(COMP.), 	and 	AUTO 	POWER 	OFF 	features 	eliminate 	the 	need 	to 	
always	use	the	POWER	button	on	the	remote	control	or	projector	cabinet.

Remote Control Precautions
•	 Handle	the	remote	control	carefully.
•	 If	the	remote 	 control 	 gets 	 wet, 	 wipe 	 it 	 dry 	 immediately.
•	 Avoid	excessive	heat	and	humidity.
•	 Do	not	heat,	take	apart,	or	throw	batteries	into	fire.
•	 If	you	will	not	be	using	the	remote	control	for	a	long	time,	remove	the	batteries.
•	 Ensure	that	you	have	the	batteries’	polarity	(+/−)	aligned	correctly.
•	 Do	not	use	new	and	old	batteries	together,	or	use	different	types	of	batteries	together.
•		 Dispose	of	used	batteries	according	to	your	local	regulations.
Operating Range for Wireless Remote Control
1Press	firmly	and 	slide 	the 	battery 	
cover	off.
2Install	new	bat teries	( AAA).	E nsure	
that	you	have 	the 	batteries’ 	polarity	
(+/−)	aligned	correctly.
•	 The	infrared	signal 	operates 	by 	line-of-sight 	up 	to 	a 	distance 	of 	about 	22 	feet/7 	m 	and 	within 	a 	60-degree 	angle 	of 	
the	remote	sensor	on	the	projector	cabinet.
•	 The	projector	will 	not 	respond	if 	there 	are 	objects 	between 	the 	remote 	control 	and 	the 	sensor, 	or 	if 	strong 	light 	falls 	
on	the	sensor.	Weak	batteries	will	also	prevent	the	remote	control	from	properly	operating	the	projector.

2. Installation and Connections
This	section	describes	how	to	set	up	your	projector	and	how	to	connect	video	and	audio	sources.
Your	projector	is	simple	to	set	up	and	use.	But	before	you	get	started,	you	must	first:
 Setting Up the Screen and the Projector
Selecting a Location 
The	further	your 	projector 	is 	from 	the 	screen 	or 	wall, 	the 	larger 	the 	image. 	The 	minimum 	size 	the 	image 	can 	be 	is 	30" 	
(0.76	m)	measured 	diagonally 	when 	the 	projector 	is 	roughly 	49 	inches 	(1.3 	m) 	from 	the 	wall 	or 	screen. 	The 	largest 	
the	image	can 	be 	is 	300" 	(7.6 	m) 	when 	the 	projector 	is 	about 	493 	inches 	(12.5 	m) 	from 	the 	wall 	or 	screen. 	Use 	the 	
chart	below	as	a	rough	guide.
1	Set	up	a	screen	and	the	projector.
2	Connect	your	computer 	or 	video	
equipment	to	the 	projector. 	See 	pages 	
12, 13, 14, 15, 16.
3	
Connect	the 	supplied 	power 	cord. 	See 	
page	16.
NOTE: Ensure that the power cord and any other 
cables are disconnected before moving the 
projector. 
NOTE:
• The distances are indicated by intermediate values between tele and wide. Use as a rule of thumb.
• The Zoom lever adjusts the image size up to +/-5%
• For more details on throw distance, see next page.

2. Installation and Connections
 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). 	([EC O 	MODE]	
is	set	automatically 	to 	[ON] 	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 	adequ ate 	ventilation 	around 	
your	projector	so 	heat 	can 	dissip ate. 	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 	
remote control to correct the orientation. ( →	page	56)
