PURPOSE:To perform appropriate relay control by performing relay control selectively based on the combination of an equipment code to judge the coincidence of equipment, an addition code to judge the necessity of relay, and an identification code to represent the requirement of the relay regardless of the addition code. CONSTITUTION:The addition code to judge the necessity of the relay, the identification code to represent the requirement of the relay regardless of the addition code, and a means 34 to perform the relay control selectively corresponding to the combination with the identification code are provided. Since the addition code to judge the necessity of the relay can be set at a repeater 3, the relay control can be omitted when it is judged that no relay is required by the addition code even when the equipment codes coincide with each other. Thereby, the appropriate relay control can be performed even at a state where a transmitter 2 set at a fixed state and the transmitter 2 set at a mobile state are used in parallel. |
