ABSTRACT:
The continuing validity of a lookup table in a radio receiver for tuning to digital audio stations is monitored. The radio receiver is tuned to a first designated frequency. A determination is made whether a station identification code is identified in a digital broadcast signal at the first designated frequency matches the designated station identification code in the table entry. The radio receiver is tuned to a next designated frequency. A determination is made whether a next station identification code identified in a next digital broadcast signal at the next designated frequency matches the next designated identification code in a next table entry. A determination is made whether an invalid table condition occurs wherein the invalid table condition is a predetermined number of non-matches from the determining steps. A message is displayed that the lookup table is invalid when the invalid table condition occurs.
