Summary:PURPOSE:To attain the correction of a registered data for abbreviation dial or preset dial while keeping on-hook by giving a registration data correction function of sequential constitution. CONSTITUTION:When an M-key is inputted once at on-hook, a sequential ROM 2 is in the data write standby mode and a data from an input terminal 6 is stored in a redial memory 4 and after data input, the M-key 1 is entered once to allow the sequential ROM 2 to be in the standby of one touch dial or abbreviation dial addressing. When an address is inputted from the input terminal 6, the content in the redial memory 4 is stored in a repertory memory 3 through a work line 6 and when the M-key 1 is operated once in place of the addressing from the input terminal 6, the sequential ROM 2 is in standby of the data write waiting mode and a correction data is able to be inputted. Thus, even when an erroneous data is registered, the data is corrected without the operation of a hook switch.
