PURPOSE: To secure the appropriate setting of operation data by display for urging the predetermined setting operation of the operation data after initializing the entire operation data when an initialization instruction is detected in a detection means. CONSTITUTION: When a power source is turned on, whether or not a clear key on an operation panel 10 is pushed is detected, and when it is pushed, the entire operation data of a memory 3 are initialized by setting a default value. Then, the setting processing of a dial system is shifted to, guidance is displayed on an LCD 11 and the dial system is set by 'DP' or 'PB' for respective outside lines 6. At the time, the default value 'DP' of the dial system of the memory 3 is displayed, and when DP is satisfactory, a key '→' is inputted and the setting of the next outside line 6 is shifted to. In the case of changing to the PB, a key '#' is inputted, the display of the LCD 11 is changed to the 'PB', the dial system of the outside line 6 of the memory 3 is changed to the PB at the time point of time when the key '→' is inputted and the setting of the next outside line 6 is shifted to.
