Connecting to a Wired LAN
The	projector	comes	standard	with	a	LAN	port	(RJ-45)	which	provides	a	LAN	connection	using	a	LAN	cable.	
To	use	 a	LAN	 connection,	 you	are	required	 to	set	 the	 LAN	 on	the	 projector	 menu.	Select	 [APPLICATION	 MENU]	→ 
[NETWORK	SETTINGS]	→	[WIRED	LAN].	(→	page	147).

6. Installation and Connections
Connecting to a Wireless LAN (sold separately)
The	separately	 sold	wireless	 LAN	unit	allows	 you	to	use	 a	wireless	 LAN	environment. 	When	 using	the	projector	 in	a	
wireless	LAN	environment,	the	IP	address	and	other	settings	must	be	made	on	the	projector.
Important:
•	 If	 you	use	 the	projector	 with	the	USB	 Wireless	 LAN	Unit	in	the	 area	 where	 the	use	 of	wireless	 LAN	equipment	 is	
prohibited,	remove	the	USB	 Wireless	LAN	Unit	from	the	projector.
•	 Buy	the	appropriate	USB	 Wireless	LAN	Unit	for	your	country	or	area.
NOTE: 
•	 The	green	LED	on	the	USB	Wireless	LAN	Unit	flashes	to	show	that	the	USB	Wireless	LAN	Unit	is	working.
•	 Your	computer’s	wireless	LAN	adapter	(or	unit)	must	be	complied	with	Wi-Fi	(IEEE802.11b/g/n)	standard.
Flow of Setting Wireless LAN
Step	1:	 Attach	the	USB	Wireless	LAN	Unit	to	the	projector. 	(→ page 179)
Step	2:	 Display	[NETWORK	SETTINGS]	from	[APPLICATION	MENU]. 	(→ page 146)
Step	3:	 Select	[NETWORK	 SETTINGS]	→	[WIRELESS	 LAN]	→	[PROFILES]	 and	set	[EASY	 CONNECTION], 	
[PROFILE	1],	or	[PROFILE	2]. 	(→ page 147)
TIP:
Access	 the	HTTP	 server	 function	 to	set	 [NETWORK	 SETTINGS]	→	[SETTINGS]	→	[WIRELESS]	→	[EASY	 CONNECTION],	 [PRO-
FILE1],	[PROFILE2].
Mounting a wireless LAN unit
NOTE:
•	
The	wireless	 LAN	unit	has	a	front	 and	a	back	 and	must	 be	mounted	 in	the	 wireless	 LAN	port	in	a	specific	 direction.	 The	port	 is	
designed so that the unit cannot be mounted in the opposite direction, but trying to push it in by force could damage the wireless 
LAN	unit	port.
•	 To	 prevent	 damage	 due	to	static	 electricity,	 touch	a	nearby	 metal	object	 (a	door	 knob,	 aluminum	 sash,	etc.)	before	 touching	 the	
wireless	LAN	unit	to	eliminate	the	static	electricity	from	your	body.
•	 Turn	off	the	main	power	before	mounting	and	removing	the	wireless	LAN	unit.
	 Mounting	 and	removing	 the	wireless	 LAN	unit	while	 the	projector’s	 power	is	on	 could	 damage	 the	wireless	 LAN	unit	or	result	 in	
malfunction	 on	the	 projector.	 If	the	 projector	 should	malfunction,	 turn	off	the	 projector’s	 power,	turn	off	the	 main	 power	 switch,	
and unplug the power cord, then plug the power cord back in. 
•	 Do	not	connect	 any	USB	 device	 other	than	the	wireless	 LAN	unit	to	the	 USB	 (LAN)	 port.	Also,	 do	not	 connect	 the	wireless	 LAN	
unit	to	the	USB	port	in	the	connector	section.

(  ).
-	 Remove	 the	wireless	 LAN	unit’s	 cap,	set	the	 unit	 with	 the	front	 (the	
side	with	the	indicator)	 facing	upwards,	 hold	the	back	 edge	 and	
insert the unit gently.
	 Next,	press	the	wireless	LAN	unit	in	with	a	finger.
-	 The	 cap	you	have	 removed 	will	 be	used	 when	 the	wireless 	LAN	 unit	
is removed, so store it in a safe place.
NOTE:	If	the	wireless	LAN	unit	is	hard	to	insert,	do	not	push	it	in	by	force.
4.	 Attach	the	anti-theft	cap	for	wireless	LAN	unit.
	 Use	the	screw	you	removed	at	Step	2	to	secure	the	anti-theft	cap.

Stacking projectors
The	projected	 image	brightness	 can	be	doubled	 by	gravity	 stacking	 up	to	two	 projectors	 without	external	 support.	This	
is	called	 “Stacking	Projection”.
 CAUTION:
A	minimum	 of	two	 persons	 are	required	 to	carry	 the	projector. 	Otherwise	 the	projector	 may	tumble	 or	drop,	 causing	
personal	injury.
NOTE:
•	 Projectors	with	different	model	numbers	cannot	be	gravity	stacked.
 Optional lenses with the same model numbers must be used for stacking pr\
ojection.
•	 The	 stacking	 projection	 does	not	support	 accuracy	 for	overlaying	 two	images	 perfectly	 so	that	 small	 text	and	detailed	 graphics	
can be clearly read or seen.
•	 Use	a	commercially	 available	distribution	 amplifier	to	both	 the	primary	 (upper)	and	the	secondary	 (lower)	projectors	 to	distribute	
signal to two outputs of the two projectors.
•	 Notes	for	stacking
-	 Ask	your	service	person	for	setting	up	and	adjusting	projectors.
-	 Set	 up	the	 projectors	 in	a	place	 or	structure	 in	a	way	 with	 sufficient	 strength	to	support	 the	combined	 weight	of	the	 two	 projec-
tors. The single projector with a lens weighs up to approximately 46 kg/\
 101 lbs.
-	 To	prevent	the	projectors	from	falling,	fasten	them	in	a	way	to	withstand	earthquakes.
-	 Double	stacking	will	cause	room	temperature	to	increase.	Ventilate	the	room	well.
-	 Do	not	attempt	to	stack	projectors	on	the	ceiling.	Gravity	stacking	cannot	be	done	on	the	ceiling.
-	 Warm	up	the	projectors	for	one	hour	before	the	desired	projection	is	obtained.
-	 Set	 up	the	 projectors	 so	that	 the	projected	 image	shows	 as	little	 geometric	 distortions	 as	possible.	 The	lens	 is	different	 in	
geometric	distortion	between	wide(+)	and	tele	(−)	for	zoom.
-	 Adjust	the	horizontal	lens	shift	to	the	lens	center.  s

Screws	(4	locations	×	4	columns)Use	the	four	screws	to	attach	each	stacking	column	to	the	projector.To	remove	each	stacking	column,	loosen	the	four	screws. 	The	screws	are	not	removable.The	four	columns	must	be	attached	back	to	the	same	positions	of	the	projector	if	they	are	needed again.

This	section	 describes	 the	simple	 maintenance	 procedures	you	should	 follow	to	clean	 the	filters,	 the	lens,	 the	cabinet,	
and	to	replace	the	lamp	and	the	filters.
❶ Cleaning the Filters
The	 air-filter	 sponge	keeps	dust	and	dirt	from	 getting	 inside	the	projector	 and	should	 be	frequently	 cleaned.	If	 the	 filter	
is	dirty	or	clogged,	your	projector	may	overheat.
NOTE:	 The	message	 for	filter	 cleaning	 will	be	displayed	 for	one	 minute	 after	the	projector	 is	turned	 on	or	off.	 When	 the	message	 is	
displayed,	clean	the	filters.	The	time	to	clean	the	filters	is	set	to	[OFF]	at	time	of	shipment.	(→ page 127)
To cancel the message, press any button on the projector cabinet or the r\
emote control.
 CAUTION
•	 Before	 cleaning	the	filters,	 turn	off	the	 projector,	 disconnect	 the	power	 cord	and	then	 allow	 the	cabinet	 to	cool. 	
Failure	to	do	so	can	result	in	electric	shock	or	burn	injuries.
Preparation: 	Before	cleaning	the	filters,	use	a	vacuum	cleaner	to	clean	the	ventilations	(inlet).
Two	filters	are	attached	on	the	left	side	and	the	front	side. 	Clean	both	filters.	Both	filters	have	the	same	shape.
When	replacing	the	filters,	buy	the	optional	filter	NP03FT	in	advance.

1.  Remove the filter cover.
(1)	Loosen	 each	of	the	 two	 knobs	 by	turning	 them	counter-
clockwise.
	 •		 The	knobs	are	not	removable.
	 •		 If	the 	knob 	is 	too 	tight 	to 	turn, 	use 	a 	Phillips 	screw-
driver.
(2)	Remove	 the	filter	 cover	 by	sliding	 it	to	 the	 left	and	 pulling	
it out.

3.	 Use	 a	vacuum	 cleaner	to	vacuum	 all	the	 dust	 from	 the	
inside	of	the	filter.
	 Get	rid	of	dust	in	the	accordion	filter.
•	 Remove	 the	dust	 inside	 the	filter	 cover	 and	the	inlet	 of	the	
projector as well. 
NOTE:
•	 Whenever	 you	vacuum	 the	filter,	 use	the	soft	 brush	 attachment	 to	
vacuum.	This	is	to	avoid	damage	to	the	filter.
•	 Do	not	wash	 the	filter	 with	water.	 Doing	so	can	 result	 in	damage	 to	
the	filter	membrane	and	also	cause	clogging.  
 4.
 Put the filter back into place.
	 Insert	the	filter	with	 “↓	AIR	FLOW	↓”	facing	the	projector.
