The	further	 your	projector	 is	from	 the	screen	 or	wall,	 the	larger	 the	image. 	The	 minimum	 size	the	image	 can	be	is	
approximately	 25"	(0.64	 m)	measured	 diagonally	 when	the	projector	 is	roughly	 37	inches	 (0.9	m)	from	 the	wall	 or	
screen. 	The	 largest	 the	image	 can	be	is	300"	 (7.6	m)	when	 the	projector	 is	about	 459	inches	 (11.7	m)	from	 the	wall	
or screen.

6. 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)	(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	
orientation. 	(→	page	87)

Computer cable (VGA) (supplied)To mini D-Sub 15-pin connector on the projector.
	It	is	recommended	that	you	use	a	commercially available distribution amplifier 
if connecting a signal cable longer than the 
cable supplied.
A commercially available 
USB cable 
(compatible with USB 2.0 
specifications)
NOTE:	
For	Mac,	 use	a	commercially	 available	
pin	adapter	 (not	supplied)	 to	connect	 to	your	
Mac’s	video	port.
Stereo mini-plug 
audio cable (not 
supplied)
 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.

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.
