If the stored information does not exist, the process proceeds to step 255 to generate an error sound and return to the standby state. If there is the stored information, the process proceeds to step 253 to select information of the first address stored in the phone book. Thereafter, in step 257, it is determined whether the selected information is a number stored in the phone book together with the name. If the number is stored together with the name, step 259 is performed. In operation 259, the name is displayed on the microphone display unit 125 and the operation proceeds to operation 263. In step 261, the number stored in the microphone display unit 125 is then displayed. Thereafter, in step 263, the controller checks whether there is a microphone key input within one minute, and if there is a key input, the process proceeds to step 265. If there is no key input, it returns to the standby state. In step 265, it is determined whether the input key is the up key 127, and if not the up key 127, the process proceeds to step 269, and if it is the up key 127, the process proceeds to step 267. In step 267, the information of the information transfer address displayed in the phone book is selected, and the process returns to step 257 and the process is repeated. If it is determined in step 269 whether the input key is the down key 131, the method proceeds to step 271 if the down key 131 is used, and proceeds to step 273 if the down key 131 is not. In step 271, the information of the address is selected after the information displayed in the phone book, and the process returns to step 257 and the process is repeated. If it is not the key key 127 (step 265) or the down key 131 (step 269) input in step 263, it is the call key 129. In step 225, it is determined whether the input of the call key is long, and if the input is short, the process returns to the standby state. If the input is long, the process proceeds to step 237. In step 237, a call is made to the other party corresponding to the displayed number, and a call connection is attempted.
