ABSTRACT:
A frequency agile data receiver checks are needed, according to a first protocol, among a plurality of channels to find a channel carrying data. A control activated by the user interrupts this first protocol and institutes a second protocol different than the first. Applied to a paging receiver, the first protocol may sequentially tune the receiver to a plurality of previously identified channels to locate a channel on which paging data is satisfactorily received. The second protocol may sequentially tune to all possible channels to locate such a channel. By this arrangement, a person who knowingly moves to a new locality (e.g., flies to another city) can instruct the paging receiver to abandon a previously identified list of candidate channels and to begin a spectrum-wide scan to locate a new satisfactory paging channels.
