Setting Your Computer Volume Control 

This is your computer desktop. In the lower right hand corner of the system tray,
there is a picture of a speaker. If the picture has a red circle with a line through it,
the volume is turned off and your headphones won’t work. Before you launch your program you must turn your volume on.

To turn volume on:

1. Left click on the speaker icon to active volume control: 
2. Click in box that says Mute to turn speaker on.
3. Click on desktop to make this icon disappear.

Now you are ready to plug in your headphones. Plug the headsets
into the back of the CPU into the green, middle slot.

Start your program.
