Adjusting the image
If necessary, adjust the height of the projector by pressing the elevator foot 
release button to extend the foot.
If necessary, rotate the leveling foot located at the rear of the projector.
Avoid placing your hands near the hot exhaust vent at the side of the 
projector.
Position the projector the desired distance from the screen at a 90 degree 
angle to the screen.
See the table listing screen sizes and distances on page 6.
Adjust the zoom or focus.
If the image is not square, first make sure that the projector is perpendicular 
to the screen. If the image is larger or smaller on the top or bottom edge of 
the screen, press the top Keystone button to reduce the upper part of the 
image, and press the bottom Keystone button to reduce the lower part.
If the left or right side of the screen is larger or smaller the other, you can 
turn the projector to the left or to the right a few degrees to square the 
image.
Adjust the Contrast or Brightness in the Basic Picture menu (on page 32).
For Aspect Ratio, keep in mind that DVD players must be configured for 
16:9 in order to view the highest quality image (
on page 11).

What is Aspect Ratio?
Aspect ratio is the ratio of the image width to image height. Standard TV 
screens and older laptops are 4:3; HDTV and most DVDs are 16:9; and 
widescreen computers are 16:10. If you are projecting onto a screen, the 
size/shape of the screen will influence the aspect ratio you decide to use. If 
you are projecting onto a blank wall, there are no screen size restrictions. 
What you plan to project will also help you choose between 4:3, 16:9 or 
16:10. Many TV shows are 4:3, while most movies are 16:9.
If you have a 16:9 screen then you should select an aspect ratio of 16:9 for 
widescreen movies or HDTV, and Native for 4:3 content. If you have a 4:3 
screen you should still use 16:9 for widescreen movies or HDTV, but you 
also have the option of using either 4:3 (to fill the screen) or Native (for 
direct pixel mapping) for 4:3 content. Force Wide can also be enabled to 
automatically resize less common aspect ratios to 16:10.

Connecting a video device
You can connect video devices such as VCRs, DVD players, camcorders, 
digital cameras, video game consoles, HDTV receivers, and TV tuners to the 
projector. You can connect the audio directly to the projector to get sound 
from the built-in speaker, or you can bypass the projector’s audio system 
and connect the audio directly from your source to a stereo or home theater 
system.
You can connect the projector to most video devices that can output video. 
You cannot directly connect the coaxial cable that enters your house from a 
cable or satellite company, the signal must pass through a tuner first. 
Examples of tuners are digital cable boxes, VCRs, digital video recorders, 
and satellite TV boxes. Basically, any device that can change channels is 
considered a tuner.
Before connecting your projector, you should decide which aspect ratio you 
want to use. The projector’s Aspect Ratio setting is accessed through the 
Resize button on the remote or through the projector’s Basic Picture Menu 
(
on page 32).
Video device connections
No video cables are provided with the projector. You can order cables from 
InFocus or provide your own.
Composite video connection
Plug the composite video cable’s yellow connector into the video-out 
connector on the video device. Plug the other yellow connector into the 
yellow Video 3 connector on the projector.
Plug the white connector of a Mini-plug audio Y-cable into the left audio 
out connector on the video device and plug the red connector into the right 
audio out connector on the video device. Plug the other end of the cable into 
the Audio In Video connector on the projector.
Keep in mind that video output from composite connections is not as high 
quality as S-video.
HDMI 1.3 connection
HDMI is a standard, uncompressed, all-digital audio/video interface. 
HDMI provides an interface between sources, such as set-top boxes, DVD 
players, and receivers and your projector. Plug an HDMI cable into the 
video-out connector on the video device and into the HDMI connector on 
the projector.
To take advantage of HDMI 1.3 Deep Color (30 bit) you must have a 1.3-
compatible source.
S-video connection
If your video device uses a round, four-prong S-video connector, plug an S-
video cable into the S-video connector on your video device and into the 
Video 2 connector on the projector. Use the audio cable as described above.
Keep in mind that S-video delivers higher quality video output than 
composite.
VGA connection
If your video device has a 15-pin VGA output, plug one end of the included 
computer cable into the VGA connector on your video source. This 
connector may be labeled “To Monitor” on the video source. Plug the 
computer cable into the VGA 2 or VGA 1 connector on the projector.
Component video connection
If your HD video device has component connectors, an optional 
Component to VGA adapter can be used. Plug the component cable into the 
video device. Plug the other end of the component cable into the adapter 
and plug the adapter into the VGA 2 or VGA 1 connector. Component offers 
the highest quality analog video output. (Digital HDMI provides the 
highest overall quality video output.)

LiteBoard™ Wand
The LiteBoard Wand works like a wireless mouse - but one that works in 
midair, not on your desktop. Just hold the wand in your hand, and point it 
at the projected image to point, click and drag. The wand works with all 
your software, just like a regular mouse.
Computer System Requirements and Connections
For the wand to work, a LiteBoard-compatible projector needs to be 
powered on and connected to your computer.
The LiteBoard Wand is compatible with any computer and operating 
system that supports a standard USB mouse (including Windows, 
Macintosh, and Linux).  To set up your computer with the wand, make sure 
a USB cable is connected between your projectors DisplayLink connector 
and a USB port on your computer.
Charging the Wand’s Battery
When the wand’s amber battery light starts to blink, its internal battery is 
low (if the battery is fully discharged, you won’t be able to turn the wand on 
by pressing its tip, L or R buttons).
To charge the battery, open the flap at the rear of the wand to expose the 
wand’s USB connector. Then connect a USB cable between the wand and 
the USB power adapter, or a computer (if connecting to a computer, make sure the computer is powered on). The battery light will stay on while the 
battery is charging, then it will turn off when the battery is fully charged.
When charging is finished, you can disconnect the USB cable (or keep the 
cable connected and use the wand while it’s charging).
NOTE: 5-10 minutes of charging is enough for about an hour of wand use. A 
full charge will take 6-8 hours and will allow 20-40 hours of non-stop wand 
use.
Caution: The lithium battery is only rechargeable, and is not user serviceable 
or user replaceable.
Caution: Always use the included USB cable and power adapter (or your 
computer) to charge the wand.
How to Use the Wand
Follow these steps to use the wand:
1Connect the projector and your computer with a USB cable (see 
Computer System Requirements and Connections above).
2Make sure the wands battery is charged or charging (see Charging the 
Wands Battery
 above).
3Turn on the projector and make sure its displaying the computers 
screen - set the source to DisplayLink, VGA 1, VGA 2, or HDMI (press 
the source button on the projector or its remote if needed - you may 
need to press it several times). 
4Turn on the wand by pressing its tip, L, or R button - the wands green 
Link light will start to blink.
5Point the wand at the screen to point, click, and drag - just like a normal 
mouse.
IMPORTANT: If you aren’t using DisplayLink to project, you must also 
connect the computer’s display output to the projector using a VGA or 
HDMI cable.

NOTE: See LiteBoard Wand Menu below for settings that let you fine-tune 
wand motion and clicking behavior. When you’re done, set the wand aside 
and make sure it isn’t pointing at the screen; it will turn itself off 
automatically after 1 minute.
If you have problems, see Troubleshooting (below).
Wand Position and Avoiding Shadows
Your Location Distance from the Screen
You can use the LiteBoard Wand right up against the screen, or around the 
room. You might find that your pointing accuracy will improve if you get 
closer to the screen. Also, avoid standing too far off from either side of the 
screen.
Avoid Shadows!
The wand wont work if its tip is in a shadow or if it is pointing at a shadow:
How to Hold the Wand
You can hold the wand the way you would hold a normal pencil or pen, or 
you can hold it like a remote control - use in whichever position is most 
comfortable. NOTES: If the wand is up close to the screen, you can press its 
tip against the projection surface to click and drag. Not recommended for 
use with fabric screens.
Using More than One Wand
The projector can work with more than one wand, but you can only use one 
wand at a time. When you want to switch to a different wand:
1Point the current wand away from the projected image for at least 3 
seconds.
2Press the tip, L, or R button on the new wand to turn it on, and then start 
using the new wand.
NOTE: Settings in the projectors LiteBoard Wand menu (see below) apply 
to all wands used with that projector.

Buttons and Wand Tip
The wands three top buttons are equivalent to the left (labeled L), right 
(labeled R), and middle (labeled M) buttons on a mouse. The wands tip is 
also a button, and its also equivalent to the left mouse button. NOTE: By 
default, the M button changes wand motion between Normal and Draw. 
Normal makes clicking easier, but Draw allows smoother motion. You can 
change the M button to perform other functions, including a standard 
middle button mouse click (see LiteBoard Wand Menu below).
Battery Light
The amber battery light shows the status of the wands built-in battery (see 
below for battery information). The battery light will turn on while the 
wand is charging, and it will blink if the battery is low (2-4 hours of wand 
use left).
Link Light
The green link light shows the status of the wands wireless connection to 
the projector. The link light will blink frequently (more than once per 
second) when the wand is attempting to link to the projector; then it will 
blink less frequently (about once every 4 seconds) after the wand has linked 
to the projector. NOTE: The link light will stay off when the wand is off.
USB Connector
The wands USB connector is behind a flap on the back of the wand. The 
USB connector is only used for charging the wands battery - using the 
included USB power adapter, or a computer. NOTE: You can use the wand 
while charging the battery, but after the battery is charged (battery light 
turns off), you can unplug the USB cable and continue to use the wand 
without a cable.
Sensor
The wands optical sensor opening is located above the wands tip. Dont 
block the sensor, and make sure it always has a clear view of the screen. 
NOTE: The sensor wont work if you point it at a shadow or away from the 
screen.
Reset Button
The wand has a reset button, behind a small hole on its underside. Under 
normal conditions, you should not need to reset the wand. See the 
Troubleshooting section below for more information.
Internal Radio
The wand has a built-in wireless transmitter/receiver which it uses to 
communicate with the projector.

Troubleshooting LiteBoard
For the most up-to-date information, visit our support site at 
www.infocus.com/support 
• If the wand doesnt work at all, or it works intermittently, try one of 
these solutions:
- Press to Move may be enabled; try holding down one of the wand’s 
buttons while moving the wand.
- Press the tip, L, or R button on the wand to turn it on.
- If the wands green Link light never blinks, then the wands battery is 
fully discharged; connect the wand to the USB power adapter or your 
computer.
- Make sure the wand is not pointing at a shadow and make sure its tip 
is not in a shadow. 
- If the room is brightly lit, reduce the room illumination.
- If youre trying to use the computers mouse at the same time as the 
wand, point the wand away from the screen while using the mouse.
- If someone else is using a different wand with the same projector, they 
must stop using it before you can use another wand.
- Change the Link Channel value in the LiteBoard Wand menu.
- Reset the wand: push the end of a paper clip into the reset opening on 
the underside of the wand.
• If accurate clicking is difficult, try one of these solutions: 
- Hold the wand steadier when clicking.
- Use the wand right up against the screen so its easier to avoid 
unexpected movements.
- Change the Motion value in the LiteBoard Wand menu.
• If it is difficult to draw or move freely because the wand wants to move 
in straight lines or draw extra lines, try changing the Motion value in 
the LiteBoard Wand menu.
• If the mouse pointer is in the wrong place on the screen, or the mouse 
pointers movement is restricted to only part of the screen, try one of 
these solutions:
- Make sure your projector is displaying the computers screen and not 
some other source (such as DVD, VCR, etc.). To change the source, 
press the Source button on the projector or its remote.
- Make sure the projector is displaying the same image as the 
computers main or built-in monitor (dont extend your desktop onto 
multiple monitors). To correct this:
On Windows XP: Open the Display control panel, click Settings, click 
the display that represents the projector, then un-check “Extend my 
Windows desktop...”.
On Windows Vista: Right-click on the desktop, choose Personalize..., 
click Display Settings, click the display that represents the projector, 
then un-check “Extend the desktop...” 
						

							17
On Macintosh: Select System Preferences from the Apple Menu, then 
select Displays. Click Arrangement, and check “Mirror Displays.”
• If the battery light does not turn on when the wand is being charged, 
try one of the following:
- Make sure a USB cable is connected between the wand and either the 
USB power adapter, or a USB port on your computer.
- If the wand is connected to the USB power adapter, make sure the 
adapter is plugged in to a live electrical outlet. If the wand is 
connected to your computer, make sure the computer is powered on.
- If the wand still wont charge, contact InFocus support at 
www.infocus.com/support.
• If DisplayLink Manager setup always starts when USB cable is 
connected, but  you dont want to use DisplayLink projection, you can 
disable DisplayLink: Go into the projectors Setup menu and turn off 
the DisplayLink Source setting. NOTE: This does not disable the 
DisplayLink connector; it only disables being able to project over 
DisplayLink.
