TIP:
•	 Image	position	can	be	adjusted	vertically	using	[POSITION]	when	the	[16:9],	[15:9],	or	[16:10]	aspect	ratios	are	selected.
•	 The	 term	“letterbox”	 refers	to	a	more	 landscape-oriented	 image	when	compared	 to	a	4:3	 image,	 which	is	the	 standard	 aspect	
ratio	for	a	video	source.
	 The	letterbox	signal	has	aspect	ratios	with	the	vista	size	“1.85:1”	or	cinema	scope	size	“2.35:1”	for	movie	film.
•	 The	term	“squeeze”	refers	to	the	compressed	image	of	which	aspect	ratio	is	converted	from	16:9	to	4:3.

Setting	ID	to	the	Projector	[CONTROL	ID]
You	can 	operate 	multiple 	projectors 	separately 	and 	independently 	with 	the 	single 	remote 	control 	that 	has 	the 	CONTROL	
ID	 function. 	If	 you	 assign	 the	same	 ID	to	all	 the	 projectors,	 you	can	 conveniently	 operate	all	the	 projectors	 together	
using	the	single	remote	control. 	To	do	so,	you	have	to	assign	an	ID	number	to	each	projector.
CONTROL ID NUMBER �������Select a number from 1 to 254 you wish to assign to your projector �
CONTROL ID �����������������������Select [OFF] to turn off the CONTROL ID setting and select [ON] to turn on the CONTROL ID set -
ting�
NOTE:	
•	 When	[ON]	is	selected	 for	[CONTROL	 ID],	the	projector	 cannot	be	operated	 by	using	 the	remote	 control	that	does	 not	support	
the	CONTROL	ID	function.	(In	this	case	the	buttons	on	the	projector	cabinet	can	be	used.)
•	 Your	setting	will	not	be	affected	even	when	[RESET]	is	done	from	the	menu.
•	 Pressing	 and	holding	 the	ENTER	 button	on	the	 projector	 cabinet	for	10	seconds	 will	display	 the	menu	 for	canceling	 the	Control	
ID.
Assigning	or	Changing	the	Control	ID
1. Turn on the projector.
2.  Press the ID SET button on the remote control.
	 The	CONTROL	ID	screen	will	be	displayed.
	 If	 the	projector	 can	be	operated	 with	the	current	 remote	control	ID,	the	 [ACTIVE]	 will	
be	displayed. 	If	 the	 projector	 cannot	be	operated	 with	the	current	 remote	control	ID,	
the	[INACTIVE]	 will	be	displayed. 	To	 operate	 the	inactive	 projector,	 assign	the	control	
ID	used	for	the	projector	by	using	the	following	procedure	(Step	3).
3.	 Press	 one	of	numeric	 keypad	buttons	 while	pressing	 and	holding	 the	ID	SET	
button on the remote control.
 Example:
	 To	assign	 “3”,	press	the	 “3”	button	on	the	remote	control.
	 No	 ID	means	 that	all	the	 projectors	 can	be	operated	 together	with	a	single	 remote	
control. 	To	set	 “No	ID”,	enter	 “000”	or	press	the	CLEAR	button.
TIP:	The	range	of	IDs	is	from	1	to	254.

AUTO ���������������������The built-in fans automatically run at a variable speed according to the\
 internal temperature�
HIGH ����������������������The built-in fans run at high speed�
HIGH ALTITUDE  �����The built-in fans run at a proper speed for low air pressure areas� Select this option when using the projector 
in low air pressure areas or at an altitude of approximately 5500 feet/1\
700 meters or higher �
When	you	wish	to	cool	down	the	temperature	inside	the	projector	quickly,	select	[HIGH]. 
						

							108
5. Using On-Screen Menu
NOTE:	
•	 It	is	recommended	that	you	select	High	speed	mode	if	you	use	the	projector	non-stop	for	consecutive	days.
•	 Set	[FAN	MODE]	to	[HIGH	ALTITUDE]	when	using	the	projector	at	altitudes	approximately	5500	feet/1700	meters	or	higher.
•	 Using	the	projector	 at	altitudes	 approximately	 5500	feet/1700	 meters	or	higher	 without	 setting	to	[HIGH	 ALTITUDE]	 can	cause	
the	projector	to	overheat	and	the	protector	could	shut	down.	If	this	happens,	wait	a	couple	minutes	and	turn	on	the	projector.
•	 Using	 the	projector	 at	altitudes	 less	than	 approximately	 5500	feet/1700	 meters	and	setting	 to	[HIGH	 ALTITUDE]	 can	cause	 the	
lamp	to	overcool,	causing	the	image	to	flicker.	Switch	[FAN	MODE]	to	[AUTO].
•	 Using	 the	projector	 at	altitudes	 approximately	 5500	feet/1700	 meters	or	higher	 can	shorten	 the	life	of	optical	 components	 such	
as	the	lamp.
•	 Your	setting	will	not	be	affected	even	when	[RESET]	is	done	from	the	menu.
TIP:	
•	 When	[HIGH	ALTITUDE]	is	selected,	an	icon	[		]	is	displayed	at	the	bottom	of	the	on-screen	menu.
Selecting	Signal	Format	[SIGNAL	SELECT]
[COMPUTER]
Allows	you	to	choose	 [COMPUTER]	 for	an	RGB	 source	 such	as	a	computer,	 or	[COMPONENT]	 for	a	component	
video	 source	 such	as	a	DVD	 player. 	Normally	 select	[RGB/COMPONENT]	 and	the	projector	 automatically	 detects	a	
component	 signal.	However	 there	may	be	some	 component	 signals	that	the	projector	 is	unable	 to	detect. 	If	 this	 is	the	
case,	select	[COMPONENT].
[VIDEO	&	S-VIDEO	System	Select]
This	feature	enables	you	to	select	composite	video	standards	automatically	or	manually.
Normally	select	[AUTO]	and	the	projector	will	automatically	detect	the	video	standard.
In	 the	 case	 where	 the	projector	 has	difficulty	 detecting	 the	video	 standard,	 select	the	appropriate	 video	standard	 from	
the menu.
This	must	 be	done	 for	VIDEO	 and	S-VIDEO	 respectively. 	Note	 that	if	you	 have	 manually	 selected	a	video	 standard	
other	than	the	video	format	of	the	current	input,	the	image	will	not	appear.
Enabling	or	Disabling	 WXGA	Mode	[WXGA	MODE]
Selecting	[ON]	will	give	 priority	 to	WXGA	 (1280	×	768)/WUXGA	 (1920	×	1200)	 signals	 in	recognizing	 an	input	 sig-
nal.
When	 [WXGA	 MODE]	is	set	 to	[ON],	 XGA	(1024	 ×	768)/UXGA	 (1600	×	1200)	 signals	 may	not	be	recognized	 on	
P501X/P451X/PE501X. 	In	this	case,	select	[OFF].
NOTE:	
•	 The	[OFF]	is	selected	at	the	time	of	shipment	of	P501X/P451X/PE501X.
•	 The	[ON]	is	selected	at	the	time	of	shipment	of	P451W/P401W.
