PROBLEM TO BE SOLVED: To be able to easily recognize the reception of a message at a pager by an earphone during listening by providing the functions of both an audio system and the pager. SOLUTION: A pager controller 5 refers to the processing state of an audio controller 17 when message information is received, and invalidates the output destination of the incoming sound selected by a switch(SW2) 12 when an audio unit 100 judges the reproducing outputting of a voice via an earphone 15. A changeover switch(SW) 13 switches the output destination to the coupler 14 side of the unit 100, and the incoming sound of the message information is output via the earphone 15 by a singing amplifier 6. |
