ABSTRACT Disclosed is a recording system including a recorder for recording dictation, a first dictate station selectively operable to provide dictation to the recorder, a second dictate station selectively operable to provide dictation to the recorder, connecting means for selectively and operably connecting the recorder to either the first dictate station or the second dictate station. The improvement provides first signal means associated with the connecting means for providing a first sequence of digital bits having a first characteristic when the recorder is operatively connected to the first dictate station and a second characteristic when the recorder is operatively connected to the second dictate station. Second signal means provide a second sequence of digital bits having a particular characteristic corresponding to a predetermined amount of the dictation being recorded by the recorder. Third signal means responsive to the connecting means becoming inoperative provide a third sequence of digital bits characterized by the time of occurrence of the third sequence of digital bits. Signal reversing means responsive to the connecting means becoming inoperative provide reversed signals comprising a reverse sequence of the first sequence of digital bits, a reverse sequence of the second sequence of digital bits, and a reverse sequence of the third sequence of digital bits. Recording means responsive to the connecting means becoming inoperative record the reversed signals on the recorder following the dictation.
