If the received frequencies are neither identical nor similar to one another in the step S20, it is checked whether the arbitrary tuner performs all the operations(S40). If so in the step S40, the tuners which gotten turned off in the step S30 get turned on and perform their original functions(S50). The arbitrary tuner and the remaining tuners receive each frequency and generate output signals in accordance with a control operation of a controller(S60).
