Reference numeral 2 is a main body of the mobile device, in which a memory 3 and a processing unit 4 are provided, and both are connected by a bus. Here, as the memory 3, an electrically rewritable nonvolatile memory E ² PROM 3 is used. In this memory 3, a telephone number for display and a telephone number for call processing are independently stored.

The processing unit 4 is a microprocessor (CPU).
Is used to set each telephone number, perform a call-in / out operation by the telephone number and display processing of the own telephone number, and read or write the contents of the memory 3. The handset 1 and the processing unit 4 are connected by a serial interface and exchange key data and display data.

Further, the mobile device main body 2 is provided with a test terminal 5 for connecting a test link 6 and is connected to the processing unit 4. The test link 6 is used when the processing unit 4 is changed to the telephone number writing mode.

Next, the operation of the automobile telephone having the above configuration will be described.

Incoming Call Operation When the received data is sent via the wireless unit (not shown), the processing unit 4 reads the telephone number for call processing from the memory 3 and compares it with the telephone number in the received data. If the telephone numbers match as a result of the comparison, a predetermined incoming call operation such as sending an incoming call response signal together with the transmission data to the outside via the wireless unit is performed.

Calling operation Enter the other party's telephone number using the dial key 10 of the handset 1. The input telephone number is input to the processing unit 4 via the serial interface. The processing unit 4 creates transmission data based on the input data, and reads out a telephone number for call processing from the memory 3 to notify from which mobile phone the call request is made, and transmits it together with the transmission data via the wireless unit. And send it to the outside.

That is, at the time of an incoming / outgoing call operation, the telephone number for call processing is used as the telephone number of the own station.

Display of the telephone number of the own station The operator performs an operation for displaying the telephone number of the own station by using the dial keys and the function keys 10 of the handset 1, and sends data to that effect to the processing unit 4. In the processing unit 4, the data input from the handset 1 is
When it is confirmed that the operation is to display the telephone number of the own station, the telephone number for display is read from the memory 3 and sent to the handset 1 via the serial interface. In the handset 1, the transmitted contents are displayed on the display unit.
Display as 11's telephone number.

Writing the telephone number of the own station First, the test link 6 is connected to the test terminal 5 of the mobile unit body 2. When the power is turned on in this state, the processing unit 4 recognizes that the test link 6 is connected via the test terminal 5.

Next, the operator uses the dial keys and the function keys 10 of the handset 1 to perform an operation for writing a telephone number of the own station. When the processing unit 4 confirms that the test link 6 is connected to the test terminal 5 and confirms the write operation from the handset 1,
