Abstract
Abstract A paging receiver has an indicator capable of illluminating in one of a plurality of colors. The color of illumination is selected in response to the address received by the pager. The indicator identifies the address by the color illuminated. The indicator also indicates weather a message is protected, read, about to be protected or about to be deleted by the color and color sequence of the indicator. The color indicator also indicates if the paging receiver is about to be turned off. The indicator may also serve as a back-light for a display when the paging receiver includes a display. Signals within the information to be displayed may change the color or change the intensity of the back-light, these signals may also turn the back-light off or on.
