A portable content-playing device which automatically constructs a virtual channel of content consistent with the tastes of the user of the device, where the content originates from one or more satellites. Specifically, the individual is administered a specific pharmacological chaperone for the lysosomal enzyme which increases trafficking of the protein from the ER to the lysosome in neural cells, with or without concomitantly increasing enzyme activity in neural cells. The status indicator may be an icon, a description, a pop-up window, a pop-up menu or any other indication that informs the user of the real-time status of the namenumber associated with the displayed event. Easy access to batteries, automated testing, high lumen outputs, efficient optics and long lamp life ensure the lowest possible life cycle costs.
