block the front or back vents. Do not use a non-approved ceiling mount. In 
the unlikely event of the bulb rupturing, thoroughly clean the area in front 
of the projector and discard any edible items that may have been placed in 
that area.

Positioning the projectorTo determine where to position the projector, consider the size and shape of 
your screen, the location of your power outlets, and the distance between 
the projector and the rest of your equipment. Here are some general guide-
lines:
 Position the projector on a flat surface at a right angle to the screen. The 
projector must be at least 4.9 feet (1.49m) from the projection screen.
 Position the projector within 10 feet (3m) of your power source and 
within 6 feet (1.8m) of your video device (unless you purchase exten-
sion cables). To ensure adequate cable access, do not place the projector 
within 6 inches (.15m) of a wall or other object.
 Position the projector the desired distance from the screen. The distance 
from the lens of the projector to the screen, the zoom setting, and the 
video format determine the size of the projected image. The top illus-
tration to the right shows three projected image sizes. For more infor-
mation about image sizes at different distances, see “Projected image 
size” on page 41.
 The image exits the projector at a given angle. This image offset is 
132.9% when the projector is in 16:9 mode (default). This means that if 
you have an image 10’ high, the bottom of the image will be 3.29’ above 
the center of the lens. 
 The image offset is 112.2% when the projector is in 4:3 mode. This 
means that if you have an image 10’ high, the bottom of the image will 
be 1.22’ above the center of the lens. 
 See “Connecting a video device” on page 11 for additional information 
on 16:9 and 4:3 modes.

Connecting a computer sourceRequired computer connectionsConnect one end of the computer cable (see page 11 for connecting video 
devices) to the dark blue Computer In connector on the projector. Connect 
the other end to the video port on your computer. If you are using a desktop 
computer, you will need to disconnect the monitor cable from the com-
puter ’s video port first. 
Connect the black power cord to the Powe r connector on the side of the pro-
jector and to your electrical outlet.
NOTE: Always use the power cord that shipped with the projector. Optional computer connectionsTo have sound with your presentation, connect an audio cable (not included 
with this projector) to your computer and to the Audio In connector on the 
projector. Visit www.infocus.com/accessories to view optional cables..
If you are using a desktop computer and want to see the image on your 
computer screen as well as on the projection screen, connect the computer ’s 
monitor cable to the Monitor Out connector on the projector. 
You can use your computer ’s mouse with an optional remote control to 
operate the navigation buttons during a presentation. The remote included 
with this projector does not allow this function. Connect the projector to the 
computer via a USB cable (not included). USB drivers must be installed to 
use the USB feature. For more information, see page 10. Visit 
www.infocus.com/accessories to view optional remote controls.

Displaying a computer source image Remove the lens cap.
To g g l e  t h e  Pow e r switch on the side of the projector to the On position.
The LED flashes green and the fans start to run. When the lamp comes on, 
the start up screen displays and the LED is steady green. It can take a 
minute for the image to achieve full brightness. 
? No start up screen? Get help on page 20.
Turn on your computer.
The computer ’s image should appear on the projection screen. If it doesn’t, 
press the Computer button on the projector ’s keypad. 
If your computer has Windows 98 as its operating system, see “Using the 
projector with Windows 98 for the first time” on page 9 regarding the driver 
setup process.
Make sure your laptop’s external video port is active. 
Many laptops do not automatically turn on their external video port when a 
projector is connected. Usually a key combination like FN + F5 is used to 
turn the external display on and off. Refer to your laptop’s documentation 
to learn your laptop’s key combination. 
? No laptop image? Try pressing the Auto Image button on the key-
pad. Get help on page 21.

Using the projector with Windows 98 for the first 
timeThe first time you connect a computer running Windows 98 to the projector, 
the computer recognizes the projector as “new hardware” and the Add 
New Hardware Wizard appears. Follow these instructions to use the Wiz-
ard to load the correct driver (which was installed with your Windows 
operating system).
If you are running Windows 2000 or Windows ME, skip these steps and go 
to “Adjusting the image” on page 8.aClick Next to begin searching for the driver.bMake sure “Search for the best driver” is selected, then click Next.cUncheck any checked boxes, then click Next. Windows automatically 
locates the driver. If this driver has been removed, reload the driver using 
your Windows operating system CD.dWhen Windows finds the driver, you are ready to install it. Click Next.
