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	if	required.
Step	2:	 Display	[NETWORK	SETTINGS]	from	[APPLICATION	MENU]. 	(→ page 120)
Step	3:	 Select	[NETWORK	 SETTINGS]	→	[WIRELESS	 LAN]	→	[PROFILES]	 and	set	[EASY	 CONNECTION], 	
[PROFILE	1],	or	[PROFILE	2]. 	(→ page 121)
TIP:
Access	 the	HTTP	 server	 function	 to	set	 [NETWORK	 SETTINGS]	→	[SETTINGS]	→	[WIRELESS]	→	[EASY	 CONNECTION]	 ,	[PRO-
FILE1],	[PROFILE2].
Mounting a wireless LAN unit
 CAUTION:
•	 The	 wireless	 LAN	unit	is	mounted	 inside	the	projector. 	Before	 mounting	 it,	turn	 off	the	 power,	 unplug	 the	power	
cord	 and	let	the	 projector	 cool	down	 completely. 	Removing	 the	filter	 unit	while	 the	projector	 is	running	 could	result	
in	burns	or	electric	shocks	from	touching	internal	parts.
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.
•	 Disconnect	the	power	cord	when	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,	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.

7. Maintenance
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.
1 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	103)
To	cancel	the	message,	press	any	button	on	the	projector	cabinet	or	the	remote	control.
The	two-layer	 filter	on	the	 projector	 improves	 cooling	and	dust-proof	 capabilities	 compared	with	the	conventional	
models.
The	outsides	(intake	side)	of	the	first	and	second	layer	filters	remove	dust.
To	clean	the	filter,	detach	the	filter	unit	and	the	filter	cover.
 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.
1. Push  up  the  buttons  on  the  left  and  right  to  release  the 
filter unit and pull it out.
2.	 Remove	the	filter	unit	by	pulling	out	the	tab.
3.  Remove the four filters.
(1)  Turn the filter unit over and pull out the two soft accordion 
filters.

7. Maintenance
(2) Push the left edges of the filters and remove the two hard 
honeycomb filters.
- The  filters  cannot  be  removed  by  pressing  the  left  and 
right edges.
4. Use a vacuum cleaner to vacuum all the dust inside.
  Get rid of dust in the accordion filter
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	filter	 clog-
ging.
5.  Remove dust from the filter unit and the filter cover.
  Clean both outside and inside.
6.	 Attach	the	four	filters	to	the	filter	unit.
(1) Insert the hard honeycomb filters into the tips of the flanges 
at the center, then bend the filters and push them in under 
the hooks.
- The filters cannot be inserted from the outside.
(2) Turn the filter unit over.
 Mount the accordion filters under the flanges along the outer 
edges.
	 •		 Each	 accordion	 filter	has	slits	 in	it.	Align	 the	slits	 with	 the	
protrusions on the filter unit.
7. Mount the filter unit back onto the projector cabinet.
 Insert the filter unit onto the projector with the sides on which 
the left and right hooks are located on the outside.

7. Maintenance
 Cleaning the Lens
•	 Turn	off	the	projector	before	cleaning.
•	 The	projector	has	a	plastic	lens.	Use	a	commercially	available	plastic	lens	cleaner.
•	 Do	not	scratch	or	mar	the	lens	surface	as	a	plastic	lens	is	easily	scratched.
•	 Never	use	alcohol	or	glass	lens	cleaner	as	doing	so	will	cause	damage	to	the	plastic	lens	surface.
 Cleaning the Cabinet
Turn	off	the	projector,	and	unplug	the	projector	before	cleaning.
•	 Use	a	dry	soft	cloth	to	wipe	dust	off	the	cabinet.
	 If	heavily	soiled,	use	a	mild	detergent. 	
•	 Never	use	strong	detergents	or	solvents	such	as	alcohol	or	thinner. 	
•	 When	cleaning	the	ventilation	 slits	or	the	 speaker	 using	a	vacuum	 cleaner,	 do	not	 force	 the	brush	 of	the	 vacuum	
cleaner	into	the	slits	of	the	cabinet.
Vacuum the dust off the ventilation slits.
•	 Clogged	ventilation	slits	may	cause	a	rise	in	the	internal	temperature	of	the	projector,	resulting	in	malfunction.
•	 Do	not	scratch	or	hit	the	cabinet	with	your	fingers	or	any	hard	objects
•	 Contact	your	dealer	for	cleaning	the	inside	of	the	projector.
NOTE:	 Do	not	 apply	 volatile	 agent	such	as	insecticide	 on	the	 cabinet,	 the	lens,	 or	the	 screen.	 Do	not	 leave	 a	rubber	 or	vinyl	 product	
in	prolonged	contact	with	it.	Otherwise	the	surface	finish	will	be	deteriorated	or	the	coating	may	be	stripped	off.
