2. Installation and Connections
Selecting a Location (LV-8310/LV-8215)
The  further  your  projector  is  from  the  screen  or  wall,  the  larger  the  image.  The  minimum  size  the  image  can  be 
is  approximately  21"  measured  diagonally  when  the  projector  is  roughly  0.8  m  (2.6')  from  the  wall  or  screen.  The 
largest the image can be is 300" when the projector is about 12.0 m (39.0') from the wall or screen. Use the draw-
ing below as a guide.
Optional axis when image is projected 
at right angle to the screen.
Throw Distance and Screen Size
Screen
H1  and  H2:  H1  is  the  height  of  the  screen  from  the  intersection  of  optical  axis  and  screen  surface,  and  H2  is  the 
height of the intersection when an image is projected at right angle to the screen.
TIP:
•	 For	the	relationship	between	the	screen	size	and	projection	distance,	see	the	table	on	page	82 , 83.
•	 The	 sizes	in	the	 above	 table	have	been	 obtained	 assuming	 that	the	aspect	 ratio	is	16:9.	 They	may	vary	 from	 the	actual	 sizes	
depending on the type of the projected image.

2. Installation and Connections
N OTE:
•	 The	Zoom	lever	adjusts	the	image	size	(diagonal)	+/-	10%.
This	projector	can	be	hung	from	the	ceiling	(Ceiling	mounted)	with	it	turned	up	side	down.
When	a	translucent	screen	is	used,	the	projector	can	project	an	image	from	behind	the	screen	(Rear).
When the projector is hung from the ceiling or projector projects an image from behind the screen, the image must be inverted 
vertically	or	horizontally.	See	page	62.
•	When	hanging	the	projector	from	the	ceiling,	optional	brackets	(part	No.	LV-CL15)	are	required.
WAR N I N G
•	 Installing	 your	projector	 on	the	 ceiling	 must	be	done	 by	a	qualified	 technician.	 Contact	your	dealer	 for	more	 in-
formation.
•	 Do	not	attempt	to	install	the	projector	yourself.
•	 Only	 use	your	 projector	 on	a	solid,	 level	surface.	 If	the	 projector	 falls	to	the	 ground,	
y

ou	can	 be	injured	 and	the	
projector severely damaged.
•	 Do	 not	use	 the	projector	 where	temperatures	 vary	greatly.	 The	projector	 must	be	used	 at	temperatures	 between	
41˚F (5˚C) and 104˚F (40˚C). (Quiet mode selected automatically at 95°F to 104°F/35°C to 40°C).
•	 Do	not	expose	the	projector	to	moisture,	dust,	or	smoke.	This	will	harm	the	screen	image.
•	 Ensure	 that	you	have	 adequate	 ventilation	 around	your	projector	 so	heat	 can	dissipate.	 Do	not	 cover	 the	vents	
on the side or the front of the projector.
Reflecting the Image
Using  a  mirror  to  reflect  your  projector’s  image  enables  you  to  enjoy  a  much  larger  image.  Contact  your  dealer  if 
you need a mirror system. If you’re using a mirror system and your image is inverted, use the MENU and 
 
buttons on your projector cabinet or your remote control to correct the orientation. See page 62 .

2. Installation and Connections
 Making Connections
NOTE:	
When	using	with	a	notebook	 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.
*	 If	 the	screen	 goes	blank	 while	using	 your	remote	 control,	 it	may	 be	the	 result	 of	the	 computer's	 screen-saver	 or	power	 man-
agement software.
Connecting Your PC or Macintosh Computer 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.
Usually,  the  combination  of  the  ‘Fn”  key  along  with  one  of  the  12  function  keys  gets  the  external  display  to  come 
on or off. For more details, refer to your computer’s owner’s manual.
NOTE: The ANALOG IN-1 and DIGITAL IN/ANALOG IN-2 connectors are supported by Plug & Play.

able pin adapter (not supplied) to connect to your Mac’s

2. Installation and Connections
NOTE: Use an audio cable without a built-in resistor. Using an audio cable with a built-in resistor turns down the sound.
NOTE:	An	image	 may	not	be	displayed	 correctly	when	a	Video	 or	S-Video	 source	is	played	 back	via	a	commercially	 available	
scan converter. 
This is because the projector will process a video signal as a computer signal at the default setting. In that case, do the following.
*	 When	an	image	is	displayed	with	the	lower	and	upper	black	portion	of	the	screen	or	a	dark	image	is	not	displayed	correctly: Project	an	image	to	fill	the	screen	and	then	press	the	AUTO	PC	button	on	the	remote	control	or	the	projector	cabinet.

2. Installation and Connections
When Viewing a DVI Digital Signal
To project a DVI digital signal, be sure to connect the PC and the projector using a DVI cable (not supplied) before 
turning on your PC or projector. Turn on the projector first and select Computer 2 (Digital) from the source menu 
before turning on your PC.
Failure to do so may not activate the digital output of the graphics card resulting in no picture being displayed. 
Should this happen, restart your PC.
Do not disconnect the DVI cable while the projector is running. If the signal cable has been disconnected and then 
re-connected, an image may not be correctly displayed. Should this happen, restart your PC.
NOTE: 
•	 Use	a 	DVI 	cable 	or 	the 	one 	compliant 	with 	the 	DDWG 	(Digital 	Display 	Working 	Group) 	DVI 	(Digital 	Visual 	Interface) 	revision 	1.0	
standard.	The	DVI	cable	should	be	within	5	m	(196)	long.	Both	single	and	dual	types	of	DVI	cable	can	be	used.
•	 The	 DVI	(DIGITAL)	 connector	 accepts	VGA	(640x480),	 SVGA	(800x600),	 1152x864,	XGA	(1024x768),	 WXGA	(1280x800	 @	up	
to	60Hz),	and	SXGA	(1280x1024	@	up	to	60Hz).

If you need to use two analog inputs simultaneously, connect a VGA cable as shown below.
NOTE:	 When	the	DVI	 to	VGA	 adapter	 is	not	 to	be	 used	 for	an	extended	 period	of	time,	 remove	 it	from	 the	projector.	 Failure	to	do	
so may cause damage to the connector of the projector.

2. Installation and Connections
Connecting an External Monitor
MONITOR OUT
You can connect a separate, external monitor to your projector to simultaneously view on a monitor the RGB ana-
log image you're projecting.
NOTE:	Daisy	chain	connection	is	not	possible.
N OTE:
•	 The	signal	from	the	DIGITAL	IN/ANALOG	IN-2	connector	cannot	be	output	from	the	MONITOR	OUT	connector.
•	 When	audio	equipment	is	connected,	the	projector	speaker	is	disabled.
•	 Use	an	audio	cable	without	a	built-in	resistor.	Using	an	audio	cable	with	a	built-in	resistor	turns	down	the	sound.

Connecting a Digital Video Signal
To  project  a  source  from  audio  video  equipment  with  a  digital  video  output  such  as  an  HDMI  or  DVI  connector, 
use a commercially available HDMI-to-DVI cable or the optional DVI digital cable to connect the Computer 2 input 
[DIGITAL	IN/ANALOG	IN-2]	connector	of	the	projector	as	shown	below.	
To output the sound in stereo, connect to audio equipment.
