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 24 to reverse the image.
2Position the projector the desired distance from the screen.
•The distance from the lens of the projector to the screen 
determines the size of the projected image. Figure 3 shows 
three projected image sizes. For more information about 
image size, see “Projected Image Size” on page 47.
3Make sure the projector and your computer are turned off.

Connecting an IBM-Compatible Computer
1Plug the   end of the CablePro Lite computer cable into the 
video connector on your computer.
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 41.
2Plug the   end of the CablePro Lite computer cable into 
the   connector on the projector.

NOTE: If you are connecting a 
desktop computer and want to 
view your presentation on your 
monitor, purchase the optional 
CablePro. Do you want to play your computer’s audio on the projector?
1Plug either end of the audio cable into the audio connector on 
your computer.
2Plug the other end of the audio cable into the   connector 
on the projector.
NOTE: If you want to control your 
computer’s mouse from the projec-
tor, purchase the optional 
CablePro and remote.

Connecting a Macintosh Computer
NOTE: Some PowerBooks require
the Apple-supplied video-out cable
or monitor adapter for external
video. Connect it between the
PowerBook and the CablePro Lite
computer cable/Mac adaptor as
shown in Figure 6.
1Plug the   end of the CablePro Lite computer cable into the 
video connector on your computer (you may need a Mac 
adaptor, ordered separately).
2Plug the CablePro Lite/Mac adaptor into the video connector 
on your computer (or the Apple video-out cable or monitor 
adapter, if needed).
3Plug the   end of the CablePro Lite computer cable into 
the   connector on the projector.
4If you want the projector display to be the same as the Power-
Book’s screen display, turn on video mirroring (called 
SimulScan in newer PowerBooks). See “Using Video Mirror-
ing with a PowerBook Computer” on page 46 for additional 
information. 
NOTE: If you are connecting a
desktop computer and want to
view your presentation on your
monitor, purchase the optional
CablePro.

Connecting a Video Player
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 40.)
2Plug the A/V cable’s yellow connector into the “video-out” 
port on your video player (Figure 7). This port 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 connector 
on the back of 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” 
port on your video player. Plug the cable’s red connector into 
the right “audio out” port on the video player (Figure 7 and 
Figure 8).
CAUTION: Your video player
may also have a “Video Out” port
for a coaxial cable connection.
DO NOT use this to connect to the
projector.•
If you’re using an S-video cable, the yellow connectors on 
the A/V cable remain unused (Figure 8).
5Plug the A/V cable’s other white and red connectors to the 
left and right “audio in” ports on the projector.
The projector is compatible with these major broadcast video 
standards: NTSC, NTSC 4.43, PAL, PAL-M, PAL-N, and SECAM. 
It automatically adjusts to optimize its performance for the 
incoming video. The input signals for SECAM, PAL-M, and 
PAL-N video are similar to other video signals and cannot be 
automatically detected, therefore they must be chosen manually. 
See “Video Standard” on page 23 for details.

Powering up the Projector and Adjusting the Image
NOTE: Always use the power cord 
that shipped with the projector.
1Remove the lens cap.
2Plug the power cord into the side of the projector, then plug it 
into your electrical outlet. A surge-protected power strip is 
recommended.
3Turn on the projector by pressing the “I” side of the power 
switch (see Figure 2 on page 3).
•The startup screen displays and the Power LED on top of 
the projector lights up (Figure 11 on page 15).
4If you connected a video player, turn it on.
•The video image should display on the projection screen. If 
a computer source is active, press the 
source button on the 
keypad (page 15) to display your video image. You can 
select a default source to determine which source the pro-
jector examines first during power-up for active video; see 
“Default Source” on page 24.
•Use the volume buttons to adjust the volume.
5Turn on your computer. 
•The computer image should display on the projection 
screen. (If a video source is active, press the 
source button to 
display your computer ’s image.)
NOTE: With some computers, 
the order in which you power up 
the equipment is very important. 
Most computers should be turned 
on last, after all other peripherals 
have been turned on. Refer to your 
computer’s documentation to 
determine the correct order. •
If necessary, make adjustments to the image from the pro-
jector ’s on-screen menus. To open the menus, press the 
menu button on the keypad, then select the Display or 
Image sub-menu. For more information about the menus, 
see page 17.

Setting up the Projector
Turning Off the Projector
If you want to turn off the projector for a short period of time, 
press the 
standby button on the keypad. This blanks the screen for 
fifteen minutes, but keeps the projector running. (You can change 
the amount of time the projector stays in standby mode; see 
“Standby Time” on page 23 for details.) After 15 minutes, the 
lamp goes out (the projector keeps running). To exit standby 
mode, press the 
standby button again. (It may take several sec-
onds for the projection lamp to reach full power and project the 
image again.)
To completely power off the projector, press the “O” side of the 
power switch on the side of the projector. If you want to turn the 
projector back on immediately, you must allow about a minute 
for the lamp to cool. The lamp won’t light if it’s too hot.
CAUTION: When you
disconnect the projector after you
have switched it off, always
remove the power cord from the
electrical outlet first, then remove
it from the projector.

USING THE PROJECTOR
This section describes how to use and make adjustments to the 
projector. It also provides a reference to the keypad buttons and 
the options available from the on-screen menus.
Basic Image Adjustment
1Make sure you have powered up your equipment in the right 
order (page 11).
2If the image doesn’t display completely, adjust the height of 
the projector (page 14) or center the image by adjusting its 
horizontal or vertical position (page 22). Be sure the projector 
is at a 90 degree angle to the screen.
3If the image is out of focus, rotate the focus ring (Figure 9).
4If the image appears to shimmer or if it has blurry vertical 
bars after you have adjusted the focus, turn Auto Image 
(page 21) off and then back on to reset the automatic sync and 
tracking. If that doesn’t clear up the image, turn Auto Image 
off and adjust the sync (page 21) and/or the tracking 
(page 22) manually.
5If the colors don’t look right, adjust the brightness (page 18).
Adjusting the Projector
To focus the image, rotate the focus ring (Figure 9) until the image 
is clear.
