Troubleshooting	on	viewing	3D	images
If	images	 will	not	 be	displayed	 in	3D	 or	3D	 images	 appear	as	2D,	 check	 the	following	 table.	Also	 refer	 to	the	 user’s	
manual	accompanied	with	your	3D	content	or	LCD	shutter	eyeglasses.
Possible	causesSolutions•	 The	content	you	are	playing	back	is	not	compatible	with	3D.•	 Play	back	a	content	compatible	with	3D.
•	 The	3D	mode	was	turned	off	for	the	selected	source.•	 Use	 the	projector’s	 menu	to	turn	 on	3D	 mode	 for	the	 selected	source. 	(→	page	106)•	 You	are	not	using	our	recommended	LCD	shutter	eyeglasses.•	 Use	our	recommended	LCD	shutter	eyeglasses. 	(→	page	67)•	 If	the 	shutter 	of 	your 	LCD 	shutter 	eyeglasses 	cannot 	synchronize	with	 the	currently	 projected	 source,	the	following	 are	possible	causes:
-	 Your	LCD	shutter	eyeglasses	are	not	switched	on.
•	 Switch	on	your	LCD	shutter	eyeglasses.For	using	a	3D	emitter:•	 Use	 an	active	 shutter-type	 3D	eyewear	 and	3D	emitter	 recom-
mended.
-	 The	battery	in	the	LCD	shutter	eyeglasses	ran	down.•	 Recharge	the	battery	or	replace	it.
-	 The	correct	eyeglass	method	is	not	selected. 	•	 Change	the	eyeglass	 method	for	3D	 by	using	 the	menu.. 	(→ page	106)
-	 The	 viewing	 distance	 between	 the	viewer	 and	the	screen	 is	too	far.
•	 Move	closer	to	the	screen	until	the	viewer	gets	3D	images. 	•	 Or	use	the	projector’s	 menu	to	select	 [NON-INVERT]	 for	[L/R	INVERT]. 	
-	 There	are	bright	 light	sources	 or	other	 projectors	 near	the	viewer.
•	 Keep	light	sources	or	other	projectors	away	from	the	viewer.•	 Do	not	look	toward	a	bright	light	source.•	 Or	 use	the	projector’s	 menu	to	select	 [NON-INVERT]	 for	[L/R	INVERT]. 	•	 If	your	 computer	 is	not	 set	for	3D	 viewing,	 the	following	 are	possible	causes:-	 Your	computer	 does	not	meet	 the	requirements	 for	3D	 view-
ing.•	 Check 	to 	see 	if 	your 	computer 	meets 	the 	requirements 	provided	in	your	user’s	manual	included	with	your	3D	content.-	 Your	computer	is	not	set	for	3D	output.•	 Set	your	computer	for	3D	output.For	using	a	3D	emitter:-	 There	 is	an	 obstacle	 between	 the	optical	 receiver	 of	the	 3D	eyewear	and	the	3D	emitter.•	 Please	remove	the	obstacle.

⓮ Connecting Your Microphone
 
Connecting	a	commercially	 available	dynamic	or	condenser	 microphone	 to	the	 MIC	 input	 jack	allows	 you	to	output	
your	mic	sound	from	the	built-in	speaker.
Sound	 from	COMPUTER,	 HDMI	1,	HDMI	 2,	and	 VIDEO	 audio	inputs	 or	sound	 of	USB-A/LAN	 input	will	be	heard	 from	
the	speaker	with	your	microphone	voice.

	 The	projector	does	not	support	NTFS	formatted	USB	memory.
	 If	the	projector	does	not	recognize	your	USB	memory,	check	if	the	format	is	supported.
	 To	format	your	USB	memory	in	your	computer,	refer	to	the	document	or	help	file	that	comes	with	your	Windows.
-	 We	do	not	warrant	that	the	USB-A	port	of	the	projector	will	support	all	USB	memories	in	the	market.

-	 If	one	folder	has	many	files,	it	takes	some	time	to	play	back.
•	 If	a	single	 folder	contains	 too	many	 files,	switching	 images	will	take	 time.	 To	shorten	 switching	 time,	reduce	 the	number	 of	images	
contained	in	a	single	folder.
TIP:	 Exchangeable	 image	file	format	 (Exif)	is	a	standard	 image	file	format	 used	by	digital	 cameras	 with	the	addition	 of	specific
