❺ Mounting the cable cover (sold separately)
Mounting	the	separately	 sold	cable	 cover	 (NP04CV)	 on	the	 projector	 allows	you	hide	 the	cables	 for	a	cleaner	
appearance.
 CAUTION
•	 After	 mounting	 the	cable	 cover,	 be	sure	 to	fasten	 using	the	screws	 provided. 	If	 not,	 the	cable	 cover	 could	fall,	
damaging	the	cable	cover	and	possibly	resulting	in	injury.
•	 Do	not	bundle	the	power	cord	and	place	it	under	the	cable	cover. 	Doing	so	could	lead	to	fire.
•	 Do	not	apply	 excessive	 force	to	the	 cable	 cover.	Doing	 so	could	 damage	 the	cable	 cover,	 resulting	 in	the	
projector	falling	or	causing	injury.
Mounting
Preparations:
1.	 Connect	the	power	cord	and	cables	to	the	projector	(the	connection	cords	are	omitted	from	the	diagrams).
2.	 Prepare	a	Phillips	screwdriver.
1. Insert the two round protrusions on the left and right edges 
of  the  cable  cover  into  the  grooves  in  the  bottom  of  the 
projector to line it up.
NOTE:	 Be	careful	 not	to	let	 the	 power	 cord	and	cables	 get	pinched	 by	the	
cable cover.
2. Turn the cable cover screw clockwise.
•	 Tighten	the	screw	securely.

(→ page 158)
•	 Has	the	lens	been	shifted	by	an	amount	exceeding	the	guaranteed	range?	(→ page 162)•	 Condensation	 may	form	 on	the	 lens	 if	the	 projector	 is	cold,	 brought	 into	a	warm	 place	and	is	then	 turned	 on.	Should this happen, let the projector stand until there is no condensati\
on on the lens�
Flicker appears on 
screen•	 Set	[FAN	MODE]	 to	other	 than	[HIGH	 ALTITUDE]	 mode	when	using	 the	projector	 at	altitudes	 approximately	 5500	feet/1600 meters or lower � Using the projector at altitudes less than approximately 5500 feet/1600 meters and setting to [HIGH ALTITUDE] can cause the lamp to overcool, causing the image to flicker � Switch [FAN MODE] to [AUTO]� (→ page 97)
Image is scrolling 
vertically, horizontally 
or both
•	 Check 	the 	computer’s 	resolution 	and 	frequency. 	Make 	sure 	that 	the 	resolution 	you 	are 	trying 	to 	display 	is 	supported	by the projector � (→ page 164)•	 Adjust	the	computer	image	manually	with	the	Horizontal/Vertical	in	the	[IMAGE	OPTIONS].	(→ page 79)

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 119 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	 Computer	 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.
