ProblemCheck	These	Items
Mic sound is not heard•	 Check	if	your	microphone	cable	is	connected	to	the	MIC	input	jack	correctly.•	 Check	if	you	use	a	dynamic	microphone.	Plug	in	power	microphones	are	not	supported	by	the	projector.	
Mic  sound  is  too  loud 
or quiet•	 Adjust	[MIC	GAIN]	from	the	menu.	(→ page 92)
For	more	information	contact	your	dealer.
If there is no picture, or the picture is not displayed correctly.
•	 Power	on	process	for	the	projector	and	the	PC.
	 Be	sure	to	connect	 the	projector	 and	notebook	 PC	while	 the	projector	 is	in	 standby	 mode	and	before	 turning	 on	
the	power	to	the	notebook	PC.
	 In	most	cases	 the	output	 signal	from	the	notebook	 PC	is	not	 turned	 on	unless	 connected	 to	the	 projector	 before	
being	powered	up.
NOTE:	You	can	check	 the	horizontal	 frequency	of	the	 current	 signal	in	the	 projector’s	 menu	under	 Information.	 If	it	reads	 “0kHz”,	
this	means	there	is	no	signal	being	output	from	the	computer.	(→	page	100	or	go	to	next	step)
•	 Enabling	the	computer’s	external	display.
	 Displaying	 an	image	 on	the	 notebook	 PC’s	screen	 does	not	necessarily	 mean	it	outputs	 a	signal	 to	the	 projector. 	
When	using	a	PC	 compatible	 laptop,	a	combination	 of	function	 keys	will	enable/disable	 the	external	 display.	Usu-
ally,	 the	combination	 of	the	 “Fn” 	key	 along	 with	one	of	the	 12	function	 keys	gets	the	external	 display	to	come	 on	
or	off. 	For	 example,	 NEC	laptops	 use	Fn	+	F3,	 while	 Dell	laptops	 use	Fn	+	F8	 key	 combinations	 to	toggle	 through	
external	display	selections.
•	 Non-standard	signal	output	from	the	computer
	 If	the	output	 signal	from	a	notebook	 PC	is	not	 an	industry	 standard,	 the	projected	 image	may	not	be	displayed	
correctly. 	Should	 this	happen,	 deactivate	 the	notebook	 PC’s	LCD	screen	 when	the	projector	 display	is	in	 use. 	Each	
notebook	 PC	has	 a	different	 way	of	deactivate/reactivate	 the	local	 LCD	screens	 as	described	 in	the	 previous	 step.	
Refer	to	your	computer’s	documentation	for	detailed	information.
•	 Image	displayed	is	incorrect	when	using	a	Mac
	 When	 using	a	Mac	 with	the	projector,	 set	the	 DIPswitch	 of	the	 Mac	 adapter	 (not	supplied	 with	the	projector)	 ac-
cording	to	your	resolution. 	After	setting,	restart	your	Mac	for	the	changes	to	take	affect.
	 For	setting	display	 modes	other	than	those	 supported	 by	your	 Mac	and	the	projector,	 changing	the	DIP	 switch	 on	
a	Mac	 adapter	 may	bounce	 an	image	 slightly	 or	may	 display	 nothing. 	Should	 this	happen,	 set	the	 DIP	 switch	 to	
the	13"	 fixed	 mode	 and	then	 restart	 your	Mac.	After	 that,	restore	 the	DIP	 switches	 to	a	displayable	 mode	and	then	
restart	the	Mac	again.
NOTE:	 A	Video	 Adapter	 cable	manufactured	 by	Apple	 Inc.	is	needed	 for	a	MacBook	 which	does	not	have	 a	mini	 D-Sub	 15-pin	
connector.
•	 Mirroring	on	a	MacBook
*	 When	 using	the	projector	 with	a	MacBook,	 output	may	not	be	set	 to	1024	 ×	768	 unless	 “mirroring” 	is	 off	 on	your	
MacBook. 	Refer	to	owner’s	manual	supplied	with	your	Mac	computer	for	mirroring.
•	 Folders	or	icons	are	hidden	on	the	Mac	screen
	 Folders	 or	icons	 may	not	be	seen	 on	the	 screen. 	Should	 this	happen,	 select	[View]	→	[Arrange]	 from	the	Apple	
menu	and	arrange	icons.
