move the battery cover.
Install  new  ones  (AA).  Ensure 
that  you  have  the  batteries’  po-
larity (+/–) aligned correctly.
Slip the cover back over the bat-
teries until it snaps into place.
NOTE:  Do  not  mix  different  types  of 
batteries or new and old batteries.
NOTE: Actual operating range may differ slightly from that shown in the \
drawing.
TIP: You can determine which remote sensor on the projector is enabled in wireless mode. The options are: front, rear or both. (→ 
page 106)
•
 
The infrared signal operates by line-of-sight up to a distance of about 22 feet/7 m and within a 60-degree angle 
of the remote sensor on the projector cabinet.
•
 
The  projector  will  not  respond  if  there  are  objects  between  the  remote  control  and  the  sensor,  or  if  strong  light 
falls on the sensor.
 
Weak batteries will also prevent the remote control from properly operat\
ing the projector.
Remote Control Precautions
•   Handle the remote control carefully.
•   If the remote control gets wet, wipe it dry immediately.
•
  Avoid excessive heat and humidity.
•
  Do not heat, take apart, or throw batteries into fire.
•
  If you will not be using the remote control for a long time, remove the \
batteries.
•
  Ensure that you have the batteries’ polarity (+/–) aligned corre\
ctly.
•
  Do not use new and old batteries together, or use different types of bat\
teries together.
•
  Dispose of used batteries according to your local regulations.

This section describes how to set up your projector and how to connect P\
Cs, video and audio sources.
2. Installation and Connections
 Setting Up the Screen and the Projector
The  further  your  projector  is  from  the  screen  or  wall,  the  larger  the  image.  The  minimum  size  the  image  can  be  is 
21 inches (0.53 m) measured diagonally when the projector is 29 inches (0.73 m) from the wall or screen. The larg-
est the image can be is 300 inches (7.62 m) when the projector is about 389 inches (9.9 m) from the wall or screen. 
Use the drawing below as a guide.
Selecting a Location
Your projector is simple to set up and use.
But before you get started, you must first:
z  Set up a screen and the projector.
x Connect your computer or video equip-
ment  to  the  projector.  See  pages 11  - 
18.
c  Connect  the  supplied  power  cable. 
See page 19.
NOTE:  Ensure  that  the  power  cable  and  any 
other cables are disconnected before moving the 
projector. When moving the projector or when it 
is not in use, cover the lens with the lens cap.
TIP: The screen sizes above are intermediate values between tele (minimum display area) and wide (maximum display area). Im-
age size can be adjusted with the zoom adjustment up to a maximum of 10%\
.

2. Installation and Connections
 Making Connections
Connecting Your PC or Macintosh Computer
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 un\
less 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 manage-
ment software.
Enabl  ng the computer’s external d  splay
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 e\
nable/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 example, NEC laptops use Fn + F3, while Dell laptops use Fn + F8 key combinations to toggle through 
external display selections.
iBM V ga  or Compatibles ( n otebook 
type) or Macintosh ( n otebook type)
NOTE: The COMPUTER 1 IN and COMPUTER 2 
IN connectors support Plug & Play (DDC2B).
NOTE:  For  older  Macintosh,  use  a  commercially 
available  pin  adapter  (not  supplied)  to  connect  to 
your Mac’s video port.
•  First turn off the computer and the projector before making connections.\
•   Turn  down  the  volume  on  the  computer  before  connecting  an  audio  cable  to  the  headphone  jack  of  the  com
-
puter.  After  connecting  the  computer  to  the  projector,  you  can  adjust  the  sound  level  on  the  computer  and  the 
projector to your preference.
•
 
You are recommended to connect an audio cable to an audio out connector \
(mini jack type) if any.
NOTE: The VT800 is not compatible with video decoded outputs of either the NEC\
 ISS-6020 or ISS-6010 switchers.

2. Installation and Connections
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 ADJ button on the remote control or the AUTO ADJUST button on 
the projector cabinet.
*
 
When noise appears on the sides of the screen:
 
Use the Overscan feature to display the image correctly.
Be  sure  to  change  the  Overscan  to  0%  before  pressing  the  AUTO  ADJ  or  AUTO  ADJUST  button,  otherwise  an  image  may  be 
displayed with its sides cut off.
•
  If  you  have  a  PC  with  a  DVI  output,  use  a  commercially  available  DVI-to-HDMI  cable  to  connect  the  PC  to  the 
HDMI  IN  connector  of  the  projector.  Only  the  digital  signal  is  available.  Connect  the  AUDIO  output  of  the  PC 
to  the  COMPUTER/COMPONENT  2  AUDIO  IN  stereo  mini  jack,  and  in  the  menu  select  [HDMI  SETTINGS] → 
[AUDIO SELECT] → [COMPUTER 2]. (→ page 109)

What   s  h DC p / h DC p  technology?
HDCP  is  an  acronym  for  High-bandwidth  Digital  Content  Protection.  High  bandwidth  Digital  Content  Protection 
(HDCP) is a system for preventing illegal copying of video data sent o\
ver a Digital Visual Interface (DVI).
If you are unable to view material via the HDMI input, this does not necessarily mean the projector is not functioning 
properly.  With  the  implementation  of  HDCP,  there  may  be  cases  in  which  certain  content  is  protected  with  HDCP 
and might not be displayed due to the decision/intention of the HDCP com\
munity (Digital Content Protection, LLC).
