Abstract:
An information receiving method comprising the steps of:providing first and second information receivers for simultaneously receiving radio waves and having tuning frequencies, the first information receiver being an FM multiplex receiver capable of receiving a first information radio wave, the first information radio wave being an FM multiplex broadcast radio wave including traffic information, the second information receiver being a radio for receiving a second information radio wave, the second information radio wave being an FM broadcast radio wave,discriminating whether the first and second information receivers are simultaneously on,establishing a prohibited tuning frequency which is capable of adversely affecting the reception of the second information receiver by local oscillation generated during the reception by the first information receiver,discriminating whether the tuning frequency of the first information receiver is equal to said prohibited frequency, andchanging the tuning frequency of the first information receiver in the case that the first and second information receivers are simultaneously on and the tuning frequency of the first information receiver is equal to the prohibited frequency.
