In the case where a judgment that a portable telephone is connected is performed (S 103), an alarm for informing the generation of condition that the telephone is left as it is connected is output (S104). This alarm is realized by supplying the predetermined alarm signal for informing that a telephone is left as it is connected from a sound synthetic processor to a speaker. Message can be output, or a predetermined alarm sound can be generated. In the case where a judgment that a telephone is disconnected is performed, this processing is concluded (S103).
