Abstract
In a telephone system, when a predetermined key of a handset unit is operated data stored in a memory incorporated within the handset unit is transferred to a memory incorporated within another handset unit, so that data that was manually input for storage in the memory of the first handset unit can be copied to the memory of a second handset unit, to eliminate the requirement to manually input the same data into the second unit.
