Choosing Your Connections
The connections you’ll need to make depend on the equipment you’re 
using, whether your presentation includes sound, and whether you 
plan to use the remote to run your presentation.

Connecting to a computer
For many presentations, the only connection you’ll need is 
between your computer and the projector. See “Connecting to a 
Computer” on page 16.

Connecting to other video sources
You can connect a VCR, camcorder, laser disc player, DVD 
player, HDTV, digital camera, or any other video source to your 
projector. You can connect the video source and a computer at 
the same time, and easily switch between sources. See 
“Connecting to Other Video Sources” on page 35.

Using the remote control
To use the remote control as a wireless mouse, you’ll need to 
connect the mouse cable. When you use the remote, you can 
locate the projector (and computer) far enough from the screen to 
get a large image, without worrying about where you stand. This 
lets you move around the room and interact with your audience, 
while still controlling your presentation. 

Including sound in your presentation
If your presentation includes sound, you can connect an audio 
cable to use the projector’s built-in stereo speakers. This is 
especially useful when the source of your presentation is a laptop.
