ABSTRACT:
A method for tracking, in a roaming receiver, RF channels in a multi-area system where each area has a unique RF channel and each unique RF channel has a unique address for each user. A plurality of telephone area codes are stored into a memory of the receiver with each of the telephone area codes corresponding to a different RF channel within the multi-area system. An address from the RF channel which is unique to the receiver for that specific RF channel is received by the receiver, each address corresponding to one of the stored telephone area codes. A telephone area code corresponding to the address is then retrieved from the receiver memory, and the telephone area code is displayed in a receiver display to allow a user to quickly recognize which area of the multi-area system the receiver is located within.
