The main control unit 11 releases the dial lock mode and shifts to the normal state (step F35). If it is determined that the voice data does not match any of the voice data, the main control unit 11 controls the display unit 10 Then, a message such as "unrecognizable" or "password error" is displayed (step F39).
[0034]
Further, the main control unit 11 controls the channel codec unit 3 and the radio unit 2 to receive control signals from a plurality of base stations (not shown), and identifies base station identification codes (CS) included in the received control signals. (ID-ID) is compared with the identification code (CS-ID) stored in the number data storage unit 8 (step F32), and is received by the radio unit 2 in the main control unit 11 and received by the channel codec unit 3. When it is determined that the identification code (CS-ID) that matches the identification code (CS-ID) included in the control data from the separated base station (not shown) is stored in the number data storage unit 8, The main controller 11 confirms the automatic flag (step F36), and releases the dial lock mode to return to the normal state only when it is confirmed that the automatic flag is set. Row (step F35).
[0035]
Further, the main control unit 11 receives a password by an operation of the operation input unit 9 by the user (step F33), and when the password matches the password stored in the number storage unit 8 (step F34). The dial lock mode is released and the mode is shifted to the normal state (step F35).
[0036]
Therefore, according to the operation control described above, the dial lock mode can be released by a user who has registered a password voice or a user who knows a specific password, and the dial lock is automatically performed only in a predetermined area. You can release the mode and use it normally.
