Portrait projection (vertical orientation)
This	projector	can	be	installed	vertically	to	display	computer	images	in	
portrait	orientation.
 Precautions during installation
•	 Please	do	not	install	the	projector	in	a	ver tical	orientation	on	top	of	the	floor	or	table	on	its	own.	If	not,	the	pro-
jector	may	fall	over,	resulting	in	injury,	damage	or	malfunction.
•	 A	stand	for	supporting	the	projector	needs	to	be	made	for	this	purpose	to	keep	intake	air	flow	securely	and	
preventive	measure	of	falling	over.	The	stand	must	be	designed	such	that	the	center	of	gr avity	of	the	projector	
is	located	well	within	the	legs	of	the	stand.	If	not,	the	projector	may	fall	over	and	result	in	injury ,	damage	and	
malfunction.
•	 If	the	projector	is	installed	on	which	the	intake	vent	facing	down,	optical	part	life	may	be	shorten.

Design and manufacturing conditions for the stand
Please	hire	an	installation	service	provider	(for	a	fee)	for	the	design	and	manufacture	of	a	customized	stand	to	be	used	
for	portrait	projection.	Please	ensure	that	the	design	complies	with	the	following	conditions:
•	 There	are	3	ventilation	holes	at	the	bottom	of	the	projector.	These	holes	should	remain	unobstr ucted.
•	 Use	the	6	screw	holes	at	the	back	of	the	projector	to	secure	it	to	the	stand.
	 Screw	hole	center	dimension:	300	×	300	(pitch	=	150)	mm
	 Screw	hole	dimension	on	the	projector:	M4	with	the	maximum	depth	16	mm
	 4	of	the	legs	can	be	unscrewed	for	removal.
•	 Horizontal	adjustment	mechanism	(for	example,	bolts	and	nuts	in	4	places)
•	 Please	design	the	stand	so	that	it	does	not	easily	topple	over.

Stacking projectors
The	projected	image	brightness	can	be	doubled	by	gravity	stacking	up	to	two	projectors	without	exter nal	support.	This	
is	called	“Stacking	Projection”.
2	projectors	can	be	stacked	on	top	of	each	other	for	“Stacking”	setup.
 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	projection.
•	 For	stacking	projectors,	attach	the	supplied	four	stacking	holders	to	the	top	of	the	lower	projector .	(→ next	page)
•	 It	does	not	support	overlay	accuracy	by	stacked	projectors.	Precise	images	as	small	texts	and	detailed	graphics	can	not	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	31	kg/	68	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.
-	 Make	sure	that	the	position	of	the	upper	projector	does	not	exceed	its	specifications.	When	setting	up	the	two	projectors,	
adjustable height range for the tilt foot on the upper projector is adde\
d to the total adjustable range.
-	 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

Attaching	Stacking	Holders
Attach	three	stacking	holders	to	three	locations	on	the	top	of	the	lower	projector.
Preparation:
Tools	required	are	Phillips	screwdriver	(plus-head)	and	four	stacking	holders	packaged	with	the	projector.
Loosen	the	tilt	foot	(four	locations)	of	the	projector.
1.	 Remove	rubber	caps	and	screws	at	four	locations.
(1)	Use	your	tweezers	or	nail	to	pinch	and	pull	up	the	rubber	cap.
(2)	Remove	the	screw	from	a	square	hole.

2.	 Attach	the	three	stacking	holders	at	four	locations.
(1)	Place	a	stacking	holder	in	a	square	hole.
(2)	Use	the	screw	removed	at	Step	1	to	fix	the	stacking	holder	in	the	square	hole.
(3)	Put	the	rubber	cap	removed	at	Step	1	back	into	the	square	hole.
	 •	 Snap	the	tabs	on	both	of	the	rubber	cap	into	the	slits	on	both	sides	in	the	square	hole.

3.	 Put	another	projector	on	the	first	projector.
	 Put	each	tilt	foot	of	the	upper	projector	on	the	stacking	holders	(four	locations).
•	 Each	tilt	foot	has	a	rubber.	Place	each	tilt	foot	r ubber	on	stac king	holders	(f our	locations).

7. Maintenance
❶ Cleaning the Lens
•	 Turn	off	the	projector	before	cleaning.
•	 Use	a	blower	or	lens	paper	to	clean	the	lens,	and	be	careful	not	to	scratch	or	mar	the	lens.
 WARNING
•	 Please	do	not	use	a	spray	containing	flammable	gas	to	remov e	dust	attached	to	the	lens,	etc.	Doing	so	may	
result	in	fires.
•	 Do	not	look	into	the	lens	while	the	projector	is	on.	Serious	damage	to	y our	e yes	could	result.
❷ 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.
•	 Poor	ventilation	caused	by	dust	accumulation	in	ventilation	openings	(also	at	the	bottom	of	the	projector)	can	result	
in	overheating	and	malfunction.	These	areas	should	be	cleaned	regularly.
•	 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.
