Introduction
Usage Guidelines
 Do not look directly into the projection lens when the projector 
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.
 This projector is not intended for use in mainframe computer 
rooms as defined in the Standard for the Protection of Elec-
tronic Computer/Data Processing Equipment, ANSI/NFPA 75.
 Transport the projector in a vendor-approved hard or soft case. 
Part numbers for these cases are listed on page 37.

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 8 feet (2.4 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.
If you are installing the projector on the ceiling, refer to the 
Ceiling Mount Installation Guide that comes with the Ceiling 
Mount Kit for more information. To turn the image upside 
down, see “Ceiling Projection” on page 23. The Ceiling 
Mount Kit is sold separately; see page 38.
2Position the projector the desired distance from the screen.
The distance from the lens of the projector to the screen and 
the zoom setting determine the size of the projected image. 
Figure 4 shows three projected image sizes. For information 
about image sizes at minimum and maximum zoom set-
tings, see “Projected Image Size” on page 45.
3Make sure the projector and your computer are turned off.

Connecting a 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.
1Plug the   end of the CableWizard Lite cable into the video 
connector on your laptop.
2Plug the   end of the CableWizard Lite cable into the
 connector on the projector ’s connector panel
FIGURE 6
Connecting the CableWizard Lite to a computer
NOTE: If you are connecting an 
older Macintosh computer that 
does not have a 15-pin connector, 
you must use a Mac adaptor 
between the computer and the 
CableWizard Lite. See “Optional 
Accessories” on page 37. 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.
Now you’re ready to power up the projector and your computer. 
Skip to “Powering up the Projector and Adjusting the Image” on 
page 10.
NOTE: If you are connecting a 
desktop computer and want to 
view your presentation on your 
monitor, purchase the optional 
CableWizard.

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. 
NOTE: HDTV sources are
connected to the projector using
the CableWizard Lite cable. See
the previous page for details.
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 37.)
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.

Setting up the Projector
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 InFocus 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 
on the keypad (page 15) 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. 
						

							11
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 discon-
nect the projector after you have 
switched it off, always remove the 
power cord from the electrical out-
let 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 10).
2If the image doesn’t display completely, zoom the image 
(page 14), 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 lens (page 14).
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).
