 Mounting a lens (sold separately)
Five	separate	 bayonet	style	lenses	 can	be	used	 with	this	projector. 	The	 descriptions	 here	are	for	the	 NP13ZL	 (2x	
zoom)	lens. 	Mount	other	lenses	in	the	same	manner.
NOTE:
•	 The	projector	and	lenses	are	made	of	precision	parts.	Do	not	subject	them	to	shock	or	excessive	forces.
•	 Remove	the	separately	 sold	lens	when	 moving	 the	projector.	 If	not,	 the	lens	 could	 be	subject	 to	shock	 while	the	projector	 is	being	
moved,	damaging	the	lens	and	the	lens	shift	mechanism.
•	 Turn	off	the	power	and	wait	for	the	cooling	fan	to	stop	before	mounting	or	removing	the	lens.
•	 Never	touch	the	lens	surface	while	the	projector	is	operating.
•	 Be	very	careful	not	to	let	dirt,	grease,	etc.,	on	the	lens	surface	and	not	to	scratch	the	lens	surface.
•	 Perform	these	operations	on	a	flat	surface	over	a	piece	of	cloth,	etc.,	to	prevent	the	lens	from	getting	scratched.
•	 When	 leaving	the	lens	 off	the	 projector	 for	long	 periods	 of	time,	 mount	 the	dust	 cap	on	the	 projector	 to	prevent	 dust	or	dirt	 from	
getting	inside.
•	 If	you	have	multiple	projectors,	be	careful	of	the	following:
-	 When	 mounting	 a	lens	 designed	 exclusively	 for	this	 projector	 onto	another	 projector	 in	the	 NP	series,	 be	sure	 to	remove	 the	
lens	attachment	 before	mounting	 the	lens	 on	the	 projector.	 The	lens	 cannot	 be	mounted	 if	its	 attachment	 is	on.	 For	 the	types	
of	lenses	that	can	be	mounted	and	instructions	on	removing	them,	see	the	lense’s	operating	instructions.
-	 Other	types	of	lenses	cannot	be	mounted	on	this	projector.
Mounting the lens
1. Remove the dust cap from the projector.
2. Remove the lens cap on the back of the lens.
3. Insert the lens onto the projector with the yellow-marked 
protrusion on the lens facing upwards.
 There is a positioning slit on the projector’s lens insertion slot. 
Insert the lens slowly all the way in, keeping the positioning 
slit at the same angle.

4. Turn the lens clockwise.
 Turn until a click is heard.
 The lens is now fastened onto the projector.
TIP:	Mounting	the	lens	theft	prevention	screw
Fasten	 the	lens	 theft	 prevention	 screw	included	 with	the	projector	 to	the	
bottom	of	the	projector	so	that	the	lens	cannot	be	removed	easily.
Removing the lens
1. While  pressing  the  lens  release  button  on  the 
p ro j e c t o r ’s   f ro n t   p a n e l   f u l ly   i n ,  t u r n   t h e   l e n s 
counterclockwise.
  The lens comes off.
NOTE: 	If 	the 	lens 	cannot 	be 	removed 	when 	the 	lens 	release	
button	 is	pressed,	 check	whether	 the	lens	 theft	 prevention	 screw	
is	mounted.
2. Slowly pull the lens off the projector.
-  After removing the lens, mount the lens caps (front 
and back) included with the lens before storing the 
lens.
- If  no  lens  is  going  to  be  mounted  on  the  projector, 
mount the dust cap included with the projector.

connected	to	the	projector,	adjust	the	volume	of	both	the	projector	and	computer	to	set	the	appropriate	volume	level.
•	 If	the	computer	has	a	mini-jack	type	audio	output	connector,	we	recommend	connecting	the	audio	cable	to	that	connector.
•	 This	projector	does	not	support	NEC	video	unit	(model	ISS-6020)	video	decoded	outputs.
•	 When 	a 	video 	deck 	is 	connected 	via 	a 	scan 	converter, 	etc., 	the 	display 	may 	not 	be 	correct 	during 	fast-forwarding 	and	
rewinding.
TIP
•	 The	 Computer	 1	and	 Computer	 2	video	 input	connectors	 support	Windows	 Plug	and	Play.	 The	Computer	 3	video	 input	connector

Cautions	when	connecting	an	HDMI	cable
•	 Use	a	certified	High	Speed	HDMI®	Cable or High	Speed	HDMI®	Cable	with	Ethernet.
Cautions	when	connecting	a	DisplayPort	cable
•	 Use	a	certified	DisplayPort	cable.
 
•	 Depending	on	the	computer,	some	time	may	be	required	until	the	image	is	displayed.
•	 Some	DisplayPort	cables	(commercially	available)	have	locks.
•	 To	disconnect	the	cable,	press	the	button	on	the	top	of	the	cable’s	connector,	then	pull	the	cable	out.
•	 No	power	is	supplied	from	the	DisplayPort	input	connector	to	the	connected	device.
•	 When	signals	from	a	device	 that	uses	 a	signal	 converter	 adapter	are	connected	 to	the	 DisplayPort	 input	connector,	
in	some	cases	the	image	may	not	be	displayed.
•	 When 	the 	HDMI 	output 	of 	a 	computer 	is 	connected 	to 	the 	DisplayPort 	input 	connector, 	use	a 	converter 	(commercially	
available).
Cautions	when	using	a	DVI	signal
•	 When	 the	computer	 has	a	DVI	 output	 connector,	 use	a	commercially	 available	converter	 cable	to	connect	 the	
computer	 to	the	 projector’s	 HDMI	input	connector	 (only	digital	 video	signals	 can	be	input). 	Also,	 connect	 the	
computer’s	 audio	output	 to	the	 projector’s	 Computer	2	audio	 input	connector. 	In	 this	 case,	 switch	 the	HDMI	 setting	
at	on-screen	menu’s	audio	selection	on	the	projector	to	[BNC].	(→	page	109)
	 To	 connect	 the	computer’s	 DVI	output	 connector	 to	the	 projector’s	 DisplayPort	 input	connector,	 use	a	commercially	
available	converter.

NOTE:	When	Viewing	a	DVI	Digital	Signal
•	 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.
•	 Some	 graphics	 cards	have	both	analog	 RGB	(15-pin	 D-Sub)	and	DVI	 (or	DFP)	 outputs.	 Use	of	the	 15-pin	 D-Sub	connector	 may	
result	in	no	picture	being	displayed	from	the	digital	output	of	the	graphics	card.
•	 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.
