A portable radio apparatus comprises an apparatus body(103) and a removable radio system unit (100) which is detachably connected to the apparatus body. The removable radio system unit (100) stores protocol specifying information which is transferred to the apparatus body when connected. A processor (401,403) of the apparatus body controls the whole operation of the radio apparatus (1) based on a protocol data set specified by the protocol specifying information received from the radio system unit. The protocol data set may be stored in the removable radio system unit. Alternatively, the apparatus body stores a plurality of protocol data sets (S1-Sn) and selects one of the protocol data sets according to the protocol specifying information. <IMAGE> |
