Setting Up the Projector 13
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 (for details, see page 34). This makes it easy to deliver your
presentation, since you won’t need to stand near your computer.
1. Locate the USB mouse cable and connect one end of the cable to
the projector’s USB port.
2. Connect the other end of the cable to the external mouse port or
USB port on your laptop, as shown.
3. If necessary, configure your laptop to work with an external
mouse.
