❶ Mounting the Optional Lens
Six	separate	 bayonet	style	lenses	 can	be	used	 with	this	projector. 	The	 descriptions	 here	are	for	the	 NP27ZL	 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	 and	turn	 off	the	 main	 power	 switch	 before	mounting	 or	removing	 the	
lens.
•	 When	dismounting 	the 	lens 	from 	the 	projector, 	return 	the 	lens 	position 	to 	the 	home 	position 	before 	turning 	off 	the 	power. 	Failure 	to	
do	so	may	prevent	the	lens	from	being	mounted	or	dismounted	because	of	narrow	space	between	the	projector	and	the	lens.
•	 Be	 sure	to	perform	 [CALIBRATION]	 after	installation	 or	replacement	 of	the	 lens.	 (→ page  19, 130)	Calibration	 corrects	the	adjust-
able zoom and focus range.
  The following lenses need calibration:
-	 NP26ZL,	NP27ZL,	NP28ZL,	NP29ZL,	NP32ZL
•	 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:
-	 The	 NP25FL,	 NP26ZL,	 NP27ZL,	NP28ZL,	NP29ZL,	and	NP32ZL	 lenses	are	designed	 exclusively	 for	this	 model	 of	the	 projector.	
These	lenses	are	not	available	on	other	projector	models.
-	 The	other	NEC	optional	lenses	cannot	be	used	with	this	model	of	the	projector.
Before mounting the lens:
•	 Prepare	a	Phillips	screwdriver	(plus-head)
•	 Remove	the	dust	cap	from	the	projector.
TIP:
•	 The	projector	comes	with	the	dust	cap	at	the	time	of	shipment

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
•	 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). 	
	 To	connect	 the	computer’s	 DVI	output	 connector	 to	the	 projector’s	 DisplayPort	 input	connector,	 use	a	commercially	
available	converter.
HDMI IN
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 grap\
hics 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.
