TIP:	For	users	of	audio	video	equipment	with	an	HDMI	terminal:
Select	“Enhanced”	rather	than	“Normal”	if	HDMI	output	is	switchable	between	“Enhanced”	and	“Normal”.
This will provide improved image contrast and more detailed dark areas.
For	more	information	on	settings,	refer	to	the	instruction	manual	of	the	audio	video	equipment	to	be	connected.
•	 When	connecting	the	HDMI	IN	terminal	of	the	projector	to	the	Blu-ra y	play er,	the	projector’s	video	lev el	can	be	
made	settings	in	accordance	with	the	Blu-ray	play er’s	video	lev el.	In	the	menu	select	[ADJUST]	→	[VIDEO]	→

❺ Connecting to a Wired LAN
The	projector	comes	standard	with	a	Ethernet/HDBaseT	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	[SETUP]	→	[NETWORK	
SETTINGS]	→	[WIRED	LAN].	(→	page	115).

❻ Connecting to a HDBaseT transmission device (sold 
commercially)
HDBaseT	is	a	connection	standard	for	home	appliances	that	is	established	by	the	HDBaseT	Alliance.
Use	a	LAN	cable	sold	commercially	to	connect	the	Ethernet	/	HDBaseT	port	of	the	projector	(RJ-45)	to	a	HDBaseT	
transmission	device	sold	commercially.
The	Ethernet/HDBaseT	port	of	the	projector	supports	HDMI	signals	(HDCP)	from	transmission	devices,	control	signals	
from	external	devices	(serial,	LAN)	and	remote	control	signals	(IR	commands).

NOTE:
•	 Never	use	the	LAN	port	(RJ-45)	on	the	projector	terminal	panel	for	connecting	a	HDBaseT	transmission	device.	It	may	cause	of	
malfunction.
•	 Please	use	a	shielded	twisted	pair	(STP)	cable	of	Category	5e	or	higher	for	the	LAN	cable	(sold	commercially).
•	 The	maximum	transmission	distance	over	the	LAN	cable	is	100	m.	(the	maximum	distance	is	70	m	for	a	4K	signal)
•	 Please	do	not	use	other	transmission	equipment	between	the	projector	and	transmission	equipment.	The	picture	quality	may	be	
deteriorated as a result.
•	 This	projector	is	not	guaranteed	to	work	with	all	HDBaseT	transmission	devices	sold	commercially.

❼ Portrait projection (vertical orientation)
If	you	install	the	projector	vertically	you	can	project	screens	from	your	
computer	and	other	sources	in	portrait	orientation.
	Precautions	during	installation
•	 Do	not	simply	set	the	projector	ver tically	on	the	floor	or	on	a	table .	The	projector	may	fall	ov er,	resulting	in	injury ,	
damage	or	malfunction.	Also	the	intake	vent	may	become	blocked	causing	the	unit’s	internal	temperature	to	
rise	resulting	in	malfunction	and	risk	of	fire.
•	 For	portrait	installation	the	intake	vents	must	be	installed	at	the	top	and	bottom.	To	ensure	air	flow	to	the	bottom	
intake	vent,	a	rack	to	support	the	unit	is	necessary .	Please	hire	an	installation	service	provider	(for	a	fee)	to	
make	a	custom	portrait	projection	stand.
•	 When	installed	in	portrait	orientation	the	projector	can	be	tilted	forward	or	backward
	 within	a	range	of	±	10°.	Tilting	the	projector	forw ard	or	backw ard	outside	of	this	range ,	or	tilting	it	to	the	left	or	
to	the	right	could	cause	it	to	malfunction.
•	 To	ensure	air	flow,	maintain	30	cm/11.8"	of	space	between	the	intake	
vent	and	the	installation	surface.
	 (NOTE)	In	the	figure	to	the	right	there	is	plenty	of	space	behind,	abov e,	
and	on	either	side	of	the	projector	unit.

Design and manufacturing conditions for the projector stand
Please	hire	an	installation	service	provider	(for	a	fee)	to	design	and	manufacture	a	customized	stand.	Please	ensure	
that	the	design	complies	with	the	following	conditions:
•	 There	is	one	intake	vent	on	either	side	and	one	exhaust	vent	at	the	rear.	These	should	remain	unobstructed.	Also,	
secure	enough	space	for	easy	filter	cover	removal	for	filter	cleaning.
•	 Remove	the	level	adjusters	or	the	projector	handles	in	case	these	hit	against	the	stand.	For	removing	the	lev el	
adjuster,	rotate	the	level	adjuster	itself,	and	for	removing	the	handle,	remove	the	handle	fastening	screws.
•	 Fix	the	stand	onto	the	ceiling	mount	screw	holes	(6	positions)	on	the	projector	bottom	face.
	 Dimensions	of	screw	hole:	for	M6	screw	Maximum	depth	10	mm	(Calculate	the	bolt	length	depending	on	the	stand	
design)
•	 Horizontal	adjustment	mechanism	(for	example,	bolts	and	nuts	in	4	places)
•	 Make	sure	to	design	the	stand	not	falling	over	easily.

 CAUTION
•	 When	moving	the	projector,	make	sure	you	hav

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.
 WARNING
•	 Please	do	not	use	a	spray	containing	flammable	gas	to	remov e	dust	attached	to	the	filters,	etc.	Doing	so	may	
result	in	fires.
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 102)
To cancel the message, press any button on the projector cabinet or the r\
emote control.
 CAUTION
•	 Before	cleaning	the	filter,	first	turn	off	the	pow er,	make	sure	the	cooling	fan	has	completely	stopped,	then	turn	
off	the	main	power	switch.	Make	sure	the	unit	has	cooled	down	completely	before	cleaning	the	filter.	Removing	
the	filter	cover	while	the	unit	is	running	could	result	in	bur ns	or	electric	shock	from	contact	with	internal	parts .
The	unit	uses	a	three	layer	metal-mesh	filter	installed	behind	the	filter	cov er.	It	can	be	used	repeatedly	by	periodical	
cleaning.
There	are	four	filters	in	total,	located	on	the	right	and	left	sides.	Clean	all	four	at	the	same	time .
Filter	cover/Filter
1. Remove the filter cover.
(1)	Twist	the	knob	to	the	left	until	it	turns	without	resistance.
(2)	Open	the	filter	cover	and	remove	it.
•	 The	knob	does	not	come	off.
•	 If	the	knob	will	not	turn,	use	a	Phillips	head	screwdriver.

2. Undo the lock lever on the filter cover and remove it.
	 If	the	filter	gets	caught	on	the	filter	cov er,	press	the	filter	cov er	
down	slightly	and	it	will	come	out.A

3. Remove the filters.
(1)	Turn	the	tabs	to	the	left	position	and	slide	the	top	filter	to	
the	right.
Ta bTabs	in	the	rear
•	 If	it	is	stuck,	slowly	inserting	the	tip	of	a	Phillips	head	
screwdriver	into	the	gap	in	a	few	places	will	loosen	it.
NOTE:
•	 Do	not	apply	a	high	degree	of	force	or	attempt	to	pry	it	open.	This	
could deform the flange making it impossible to reattach the filter 
cover.
 
 
(2)	With	the	tabs	still	on	the	left-facing	position,	remov
e	the	
filter	inside	by	pulling	it	toward	you.
	 All	three	layers	of	the	filter	will	come	out.
4.	 Clean	all	the	dust	from	the	filters	using	a	vacuum	cleaner .
	 Carefully	remove	the	dust	from	the	filter	cov ers	as	well	as	
from	both	sides	of	all	the	filters.
7. Maintenance  
						

							144
	 Remove	the	du st	fr om	th e	gr ates	on	th e	ou tside	of	th e	pr ojec-
tor	as	well.
•	 Some	intake	vents	do	not	have	gr ates.	Be	sure	to	also	
remove	any	dust	stuck	to	the	louver	(blind	with	angled	
horizontal	slats)	with	a	vacuum	cleaner.
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.

NOTE:
•	 Before	turning	on	the	powermake	sure	that	all	filter	covers	are	in	place.	If	they	are	not	fitted	properly	dust	could	get	inside	the	
projector causing it to malfunction.
•	 Reset	[FILTER	HOURS	USED]	after	cleaning	the	filters.	To	reset	go	to	the	on	screen	menu	and	select	[SETUP]	→	[RESET]	→
