What does the red "X" in the top right hand corner of the Brainwave Visualizer indicate?

The red "X" in the corner indicates that the MindSet headset is not detecting any brainwaves. If you see the red "X" frequently while wearing the headset on your head, please make sure the headset's contacts are clean (clean with alcohol wipes periodically), and that they are properly contacting the skin of your forehead and ears.
