I think it means if you have Bluetooth installed on your computer, you can access your phone using it. I have bluetooth on my computer, it's a Mac, and I have a bluetooth Mouse and printer so I don't need to be plugged into said items to print or use the mouse..
If you have bluetooth on your computer, click on the icon in the corner ( a weird lookin B ) and click on "set up bluetooth device". And it will go to a page after you hit continue that asks you to select device type. You can click on Mobile Phone or Other Device and it will pick up ALL bluetooth ready devices. It'll pick up your phone if you have it on I think, and from there I don't know cause I don't have my phone set up with it.
