Patent ID: 7817965

Claim:
A scanning radio receiver for scanning a plurality of radio frequencies and tuning said scanning radio receiver to each of said frequencies and, when an audio signal is detected for any one of said radio frequencies, remaining tuned to that frequency for a period of time and processing said audio signal to cause said scanning radio receiver to play said audio signal for said period of time, said scanning radio receiver having a plurality of user-programmable operating functions, said scanning radio receiver comprising: a housing; a working, non-volatile memory disposed in the housing; an auxiliary, non-volatile memory disposed in said housing; a user interface on said housing which is user operable to program functions of the scanning radio receiver, to define a first operating configuration, and store the first operating configuration in said working memory, wherein the user interface is user operable to program functions of the scanning radio receiver to define a second operating configuration, and store the second operating configuration in said auxiliary memory simultaneously with said first operating configuration being stored in said working memory, wherein the user interface is user operable to select between the first and second operating configurations, wherein each operating configuration comprises a set of scanning radio receiver functions which have been programmed by the user using the user interface, wherein the scanning radio receiver is workable using either the first or second operating configuration, but the user interface is useable to select which of the first and second operating configurations is used by the scanning radio receiver.
