Usage Guidelines
 Do not look directly into the projection lens when the lamp is 
turned on. The bright light may harm your eyes.
 Do not block the grills on the projector. Restricting the air flow 
can cause it to overheat and turn off. If this happens, you must 
wait a minute before attempting to turn it back on.
 Handle the projector as you would any product with glass 
components. Be especially careful not to drop it.
 Avoid leaving the projector in direct sunlight or extreme cold 
for extended periods of time. If this happens, allow it to reach 
room temperature before use.
Transport the projector in a vendor-approved hard or soft case. 
Part numbers for these cases are listed on page 44.

SETTING UP THE PROJECTOR
1Place the projector on a flat surface.
The projector must be within 10 feet (3 m) of your power 
source and within 6 feet (1.8 m) of your computer.
If you want to project from behind a translucent screen, set 
up the projector behind your screen. See “Rear Projection” 
on page 31 to reverse the image.
If you are installing the projector on the ceiling, refer to the 
installation guide that comes with the Ceiling Mount Kit for 
more information. To turn the image upside down, see 
“Ceiling Projection” on page 31. The Ceiling Mount Kit is 
sold separately; see “Optional Accessories” on page 44.
2Position the projector the desired distance from the screen.
The distance from the lens of the projector to the screen and 
the zoom lens setting determine the size of the projected 
image. Table 1 shows example projected image sizes and 
minimum and maximum distances to the screen.
The formulas for distance to the screen are:
Max distance (ft) = diagonal image size (ft) ÷.49
Min distance (ft) = diagonal image size (ft) ÷.69
NOTE: For a similar table for the 
optional short throw and long 
throw lenses, see page 52 of the 
Appendix.Ta b l e  1 :

NOTE: The CableWizard
connector is used with the optional
CableWizard2 or 3, a connection
hub containing mouse, audio,
monitor and computer connectors.
It is optimized for ceiling-mounted
installations, and can be used with
a 60’ extension cable. See
“Optional Accessories” on
page 44. This input is designated
Computer CableWizard.
Once you know the diagonal image size, you can figure out the 
width and height using these formulas:
width (inches) = diagonal (inches) x 0.8
height (inches) = width (inches) x 0.75
3Make sure the projector is unplugged and your computer is 
turned off. Now you’re ready to connect your equipment.

Setting up the Projector
Connecting a Computer Using a VESA Cable
This input is designated Computer VESA.
NOTE: If you are connecting an
older Macintosh computer that
has a 2-row 15-pin connector, you
must use a Mac adaptor between
the computer and the projector.
See “Optional Accessories” on
page 44.
1Plug one end of the supplied VESA cable into the video con-
nector on your computer. Plug the other end into the VESA 
connector on the projector.
2If you want audio with your presentation, plug an audio cable 
(not supplied) into the audio connector on your computer. 
Plug the other end into a   In connector on the projector.
FIGURE 5
Connecting the projector to a computer using a VESA cable
NOTE: When all 5 BNCs are
connected, the projector handles
separate synch on H and V. When
4 BNCs are connected, the
projector handles a composite sync
on H. When 3 BNCs are
connected, the projector handles a
composite sync on G.
Connecting a USB type B mouse
You can control the computer ’s mouse with the projector ’s key-
pad or remote by connecting a USB mouse cable to the USB con-
nector on the projector (Figure 4 on page 7) and on your 
computer. This feature is available for PC Computer RGBHV and 
VESA sources only. It is not supported on the Macintosh plat-
form. See page 32 for menu options that apply to a USB type B 
mouse.
Connecting a Computer using BNC Cables
Connect the BNC cables to the appropriate RGBHV connectors 
on the projector (Figure 4 on page 7) and on your computer. 
This input is designated Computer RGBHV.

Connecting a Computer with an M1-DA Cable
See “Optional Accessories” on page 44 to order this cable. 
This input is designated Computer M1 Analog or Computer M1 
Digital.
1Plug the   end of the M1-DA computer cable into the 
M1-DA connector on the projector.
NOTE: Many laptop computers 
do not automatically turn on their 
external video port when a sec-
ondary display device such as a 
projector is connected. Refer to 
your computer manual for the 
command that activates the exter-
nal video port. Activation com-
mands for some laptop computers 
are listed in the Appendix of this 
manual on page 46.
2Plug the   end of the M1-DA computer cable into the video 
connector on your computer.
FIGURE 6
Connecting the projector to a computer using the M1-DA cable
Do you want to control the computer’s mouse from the projector’s 
remote or keypad?
NOTE: The USB mouse is sup-
ported for use with 
Windows 98, Windows 2000, and 
Apple OS 8.5 and higher only.
1Plug the   end of the M1-DA computer cable into a 
USB mouse connector on your computer. 
Do you want to play your computer’s audio on the projector?
1Plug an audio cable (not supplied) into the audio connector 
on your computer.
NOTE: You do not need to restart 
your computer after connecting a 
USB mouse to use it (it is hot-plug-
gable). 
2Plug the other end of the audio cable into a   In connector 
on the projector.

Setting up the Projector
Connecting a Computer with an RS-232 Cable
You can control the projector from an LCD control panel by con-
necting an RS-232 cable to the projector (see Figure 4 on page 7). 
See “RS232 Terminal Specifications” on page 53 for details.
Connecting a Video Player
There are 3 video inputs: Composite video, S-video, and Compo-
nent video. For Composite and S-video, follow these instructions:
1If your video player uses a round, one-prong composite video 
connector, you’ll need only the A/V cable that shipped with 
the projector. 
If your video player uses a round, four-prong S-video con-
nector, you’ll need an S-video cable in addition to the A/V 
cable. The S-video cable is sold separately. (See “Optional 
Accessories” on page 44.)
NOTE: HDTV sources are
connected to the projector using
the computer inputs, not the video
inputs. All analog computer inputs
can display HDTV. See the
previous pages for computer
connection instructions.
2Plug the A/V cable’s yellow connector into the “video-out” 
connector on your video player (Figure 7). This connector 
may be labeled “To Monitor.”
If you’re using an S-video cable, connect it to the “S-video 
out” connector on the video player (Figure 8).
3Plug the other yellow connector into the composite video con-
nector
 on the projector.
If you’re using S-video, plug the other end of the cable into 
the “S-video” connector
 on the projector (Figure 8).

4Plug the A/V cable’s white connector into the left “audio out” 
connector on your video player. Plug the cable’s red connector 
into the right “audio out” connector on the video player (Fig-
ure 7 and Figure 8).
CAUTION: Your video player 
may also have a “Video Out” con-
nector for a coaxial cable connec-
tion. DO NOT use this to connect 
to the projector. 
5Plug the A/V cable’s other white and red connectors to the 
left and right   In ports on the projector.
The projector is compatible with these major broadcast video 
standards: NTSC, NTSC 4.43, PAL, PAL-M, PAL-N, PAL-60, and 
SECAM. It automatically adjusts to optimize its performance for 
the incoming video. The input signals for SECAM, PAL-M, 
PAL-N and PAL-60 video cannot be automatically detected, 
therefore they must be chosen manually. See “Video Standard” on 
page 30 for details. 
Connecting a Video Player using BNC Cables
Connect the BNC cables and audio cables to the appropriate con-
nectors on the projector (Figure 4 on page 7) and on your video 
player. 
This input is designated Component Video.

Connecting External Speakers 
To connect one or two external speakers, plug the speaker cable 
into the   out (audio out) connectors on the projector. The 
external speaker ’s volume is controlled by the projector; see “Vol-
ume + or -” on page 21.
FIGURE 9
Connecting external speakers
Connecting the Remote Control Cable
If the projector cannot receive the remote’s signal, as may be the 
case if you’re using rear projection, connect the remote directly to 
the projector with the optional remote cable. See “Optional 
Accessories” on page 44.
NOTE: For more information on
using the remote, see page 17.
1Plug the remote cable into the wired remote connector on the 
projector.
2Plug the other end into the connector on the remote.
