Setting Up the Projector
This chapter tells you how to set up the projector and connect it to a 
computer or video source. You can connect up to two devices 
simultaneously: two computers or two video sources or one of each. 
You’ll find instructions for the following in this chapter:
■Positioning the projector
■Connecting to a computer
■Connecting to video sources

Positioning the Projector
Before connecting the projector, you 
need to decide where to place it. If 
you’re setting up the projector yourself 
and it isn’t already installed in the 
room you’re using, you’ll probably 
want to place it on a table in front of 
the screen, as shown. 
This lets you stand in the front of the room, face the audience, and 
remain close enough to the equipment to be able to control it. Try to 
leave as much space as possible between the projector and...

Setting Up the Projector15
Try to place the projector directly in front of the center of the screen, 
facing it toward the screen squarely. If the projector isn’t positioned 
this way, the image will be “keystone” shaped, instead of square or 
rectangular.
If you place the projector below the level of the screen, you’ll have to 
tilt it up by extending the feet. This also causes the image to lose its 
rectangular shape, but the Auto Keystone feature corrects the 
distortion automatically. If the image...

3. Connect one end of the cable to the projector’s 
Computer1/Component Video1 or the 
Computer2/Component Video2 port. If you are going to 
connect your computer monitor to the projector for simultaneous 
display, use the 
Computer1/Component Video1 port. 
4. Connect the other end of the cable to your computer’s video-out 
or monitor port. 
If you’re using a PowerBook or iBook and you can’t connect the 
cable, you may need to use the Macintosh desktop adapter as 
shown below...

18Setting Up the ProjectorAfter projection starts, select the correct source (either 
Computer1 or 
Computer2) when you want to project this source. See page 30.
If you don’t need to make any other connections, you can plug in 
your projector and turn it on. See page 28 for instructions.
 
Connecting a Monitor
If you want to see your presentation close-up as well as on the screen, 
you can connect an external monitor to the projector. This lets you 
view images on your computer monitor while the...

Connecting the Cable for Remote Mouse 
Control
Using the remote control as a wireless mouse lets you click through 
slideshow-style presentations, such as PowerPoint, from up to 20 feet 
away. This makes it easy to deliver your presentation, since you won’t 
need to stand near your computer. 
To use the wireless mouse function, your system must have a USB 
port and the full version of one of these operating systems: 
1. If you are using a desktop computer, disconnect the mouse...

Amplifying Computer Audio
Your computer probably has its own sound system; however, it may 
not be adequate for your presentation. If you need more volume, you 
can connect a computer audio cable to take advantage of the 
projector’s built-in amplifier and speaker. You can obtain a computer 
audio cable (3.5-mm stereo miniplug cable) from a computer or 
electronics dealer.
1. Connect one end of the audio cable to the 
Audio1 jack on the 
projector.
2. Connect the other end of...
