ABSTRACT:
In conventional radio controlled models, a receive frequency is changed with a changeover switch mounted in a receiver body. In the present invention, a frequency switching scheme, employing a radio system in which a transmitter switches the receive frequency, is provided. Using weak radio waves usable without authorization, the transmitter transmits frequency data set therein as a frequency switching signal to a receiver. In the receiver, the receive frequency is set to a predetermined weak radio wave frequency when the power source is turned on. Upon receiving the weak radio waves, the receiver reads the frequency data out of the set signal and stores it into the memory means. Thus, the frequency setting has been completed. When the receiver does not receive the frequency switching signal for a fixed period of time, it reads out the frequency data used previously from the data memory to start the receiving operation.
