 Setting Up the Screen and the Projector
Selecting a Location
The further your projector is from the screen or wall, the larger the image. The minimum size the image can be is
approximately 25 measured diagonally when the projector is roughly 0.9 m (3\
.1’) from the wall or screen. The largest
the image can be is 300 when the projector is about 7.6 m (25.0’) \
from the wall or screen. Use the drawing below as
a guide.
NOTE:
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 fr\
om behind the screen (Rear).When the projector is hung from the ceiling or projector projects an ima\
ge from behind the screen, the image must be inverted
vertically or horizontally. See page 
43 .
• When hanging the projector from the ceiling, optional brackets (pa\
rt No. LV-CL12) are required.
TIP:
• For the relationship between the screen size and projection distance, se\
e the table on page  61 .
• The sizes in the above table have been  obtained assuming that the aspec\
t ratio is 4:3. They may vary from the actual sizes
depending on the type of the projected image.
• The Zoom lever adjusts the image size (diagonal) +/- 20%.

2. Installation and Connections
W ARNING
• Installing your projector on the ceiling must be done
by  a qualified technician. Contact your dealer for more
information.
• Do not attempt to install the projector yourself.
• Only use your projector on a solid, level surface. If the
projector falls to the ground, you 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 95˚F (35˚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 projectors image enables
you to enjoy a much larger image. Contact your dealer if
y ou need a mirror system. If youre using a mirror sys-
tem and your image is inverted, use the MENU and
SELECT 
  b uttons on your projector cabinet or
y our remote control to correct the orientation. See page
43
.

2. Installation and Connections
 Making Connections
NOTE: When using with a notebook PC, be sure to connect between the proj\
ector and the notebook PC before turning on the
power to the notebook PC. In most cases signal cannot be output from RGB\
 output unless the notebook PC is turned on after
connecting with the projector.* If the screen goes blank while using your remote control, it may be the \
result of the computers screen-saver or power
management software.

Connecting Your PC or Macintosh Computer
NOTE: The COMPUTER 1 connector supports Plug & Play (DDC2).
VGA cable (supplied)To  mini D-Sub 15-pin connector on the projector. It
is recommended that you use a commercially av ailable distribution amplifier if connecting a
signal cable longer than the supplied one.A udio cable
(not supplied)
IBM PC or Compatibles (Desktop type) or Macintosh (Desktop type)
NOTE: For older Macintosh, use a
commercially available pin adapter(not supplied) to connect to your
Macs video port.
IBM VGA or Compatibles (Notebooktype) or Macintosh (Notebook type)
NOTE: Use an audio cable without a built-in resistor. Using an audio cable with a built-in resistor turns down the sound.
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: An image may not be displayed correctly when a Video or S-Video so\
urce 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 fol lowing.
* 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.
