Abstract
A key telephone system includes a temporary registration memory for temporarily storing operating data and a final registration timing data memory for storing final registration timing data, including a timing condition for transferring contents of the temporary registration memory to the operating data memory. Operating data input by a user and the final registration timing data are written into the temporary registration memory and the final registration timing data memory, respectively, from a data input unit connected to the main unit during a data setting mode. The system discriminates establishment of the timing condition designated in accordance with the final registration timing data stored in the final registration timing data memory, whereupon the operating data stored in the temporary registration memory is transferred to the operating data memory.
