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-

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 CableWizard
Lite computer cable/Mac adaptor
as shown in Figure 6.
1Plug the   end of the CableWizard Lite computer cable into 
the In Focus-supplied Mac adaptor.
2Plug the CableWizard Lite/Mac adaptor into the video con-
nector on your computer (or the Apple video-out cable or 
monitor adapter, if needed).
3Plug the   end of the CableWizard 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 42 for additional 
information. 
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. 
•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 “Accesso-
ries” on page 35.)
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 22 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 if power surges are common in your area.
3Turn on the projector.
•The In Focus startup screen displays and the Power LED on 
top of the projector lights.
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 23.
•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 menu. For more information about the menus, see 
page 16.

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. After 15 min-
utes, the lamp goes out (the projector keeps running). To exit 
standby mode, press the 
standby button again. (It takes several 
seconds 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.
NOTE: In Focus has created a 
software program called In Focus 
Presents that automatically opti-
mizes your computer’s display 
when used with any In Focus pro-
jector. This free program is 
included with every projector and 
available for download from our 
website at
 www.infocus.com.
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 21). 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 13).
4If the image appears to shimmer or if it has blurry vertical 
bars after you have adjusted the focus, turn Auto Image 
(page 20) off and then back on to reset the automatic sync and 
tracking. If that doesn’t clear up the image, turn Auto Image 
off adjust the sync (page 21) and/or the tracking (page 21) 
manually.
5If the colors don’t look right, adjust the brightness (page 17).

Using the Keypad Buttons
The keypad is lit orange when the projector is on and lit green 
while the menus are displayed. While the menus are displayed,

and video) connected to the projector, select between them by 
pressing the button.
Standby  
When you press standby, the display and audio turn off and a 
blank screen is displayed for 15 minutes.
•If you press standby again within 15 minutes, the projector 
returns to normal operations immediately.
•If you press standby again after 15 minutes, there is about a 
30 second delay before the lamp turns back on.
•If you don’t press standby again, the lamp turns off after 15 
minutes.

Using the On-Screen Menus
The projector
 has four on-screen menus that allow you to make 
image adjustments and change a variety of settings. Most of these 
adjustments aren’t available directly from the keypad. 
To open the on-screen menus, press the 
menu button on the key-
pad. This changes the volume, source, and standby buttons on 
the keypad to menu navigation buttons (and illuminates the key-
pad green). Press the corresponding buttons to move the cursor 
up, down, left, or right. To select a menu, use these buttons to 
move the cursor to the tab for the menu you want, then click 
either mouse button. To change a menu setting, move the cursor 
to the setting you want to change using the navigation buttons, 
then use one of the two mouse buttons to make changes. Press 
menu again when you want to close the menus. All changes are 
saved when you close the menus.
The status bar at the top of the menu display indicates the source 
that is currently active (Computer or Video) and any peripherals 
that are connected. It also contains a lamp hour counter that 
starts at zero hours and counts each hour the lamp is in use. 
Change the bulb when the brightness is no longer acceptable. See 
“Replacing the Projection Lamp” on page 25 for details.
