PURPOSE:To utilize a receiver at plural zones by including a zone designation signal to a synchronizing signal so as to give plural numbers to the receiver. CONSTITUTION:A zone designation signal and a frequency designation signal are added to a synchronizing signal for each group. An address signal detection section 3 detects a selective call signal and an address of its own receiver set to a memory 7 is reads from the detected output of a zone designation signal detection section 4, collated by an address signal collation section 6 and the result of collation is outputted. Moreover, a frequency designation signal detection section 5 detects a frequency designation signal the signal is collated with a channel number decided by a zone designation signal by a channel collation section 8 to control a frequency switching control section 9 controlling the frequency switching of the reception circuit 2 to make the frequency coincident with each other. Thus, one set of receiver is used in plural zones and in plural frequencies. |
