PURPOSE:To attain clear talking of one to one by using radio for talking between a handset and a case and mounting the handset to a head of a body. CONSTITUTION:In hooking off the handset for call, a hook switch is activated and a call tone is listened to through a receiver. Then the opposite party is called by using similar procedure as a conventional telephone set. As to an incoming call, when a call is generated similarly as the conventional telephone set, the talking is attained by hooking off the handset. Since the handset is mounted on the head of body during talking, the trouble of holding the handset is avoided. Thus, a wide range is moved freely without carrying the handset during talking and clear talking of one to one is attained. |
