An encoding of K blocks of information for transmission on N subchannels, responsive to a number of redundant blocks M, employs one of multiple check codes depending on the number of redundant blocks M and employs multiple processes for determining a code for the K blocks of information depending on the number of redundant blocks M and K blocks of information together. The utterance type vehicle-mounted device is comprised of a predetermined operation unit and a control unit. Parameter data indicates parameters in network protocol headers for a short message. The hydrophobically-modified RPM can be formed and introduced into the formation in several ways.
