	 PJLink	 is	a	standardization	 of	protocol	 used	for	controlling	 projectors	
of  different  manufacturers.  This  standard  protocol  is  established  by 
Japan	Business	 Machine	and	Information	 System	Industries	 Associa-
tion	(JBMIA)	in	2005.
	 The	projector	supports	all	the	commands	of	PJLink	Class	1.

power is not supplied to the projector for two weeks or more, the built-\
in clock stops working.

6. Connecting to Other Equipment
 Mounting a lens (sold separately)
Six	separate	 bayonet	style	lenses	 can	be	used	 with	this	projector. 	The	 descriptions	 here	are	for	the	 NP18ZL	 (1.3x	
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	 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.
•	 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	following	lenses	designed	exclusively	for	this	projector	cannot	mounted	onto	another	projector.
-	 NP16FL/NP17ZL/NP18ZL/NP19ZL/NP20ZL/NP21ZL
Mounting the lens
1.	 Remove	the	dust	cap	from	the	projector.
2.	 Remove	the	lens	cap	on	the	back	of	the	lens.
•	 The	lens	NP18ZL	is	used	as	an	example.
3.	 Insert	 the	lens	 onto	 the	projector	 with	the	arrow	 mark	in	
the	label	on	the	lens	facing	upwards.
	 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
Before removing the lens:
1.	 Turn	on	the	projector	and	display	an	image. 	(→	page	16)
2.	 Press	and	hold	the	SHUTTER/HOME	POSITION	button	for	2	seconds.
 The lens position will be moved to the home position.
3.	 Turn	off	the	projector, 	turn	off	the	main	power	switch, 	and	then	unplug	the	power	cord. 	
4.	 Wait	until	the	projector	cabinet	is	cool	enough	to	handle.
1.	 While	pressing 	the 	lens 	release 	button 	on 	the 	projector’s	
front	panel	fully	in, 	turn	the	lens	counterclockwise.
 The lens comes off.
NOTE:	 If	the	 lens	 cannot	 be	removed	 when	the	lens	 release	 (PUSH	
RELEASE 	LENS) 	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.
