THE DICTATING UNIT HAS AN ASSOCIATED MICROPHONE WITH CONTROL BUTTONS FOR ESTABLISHING MODES OF OPERATION, INITIATING FORWARD AND BACKSPACING MOVEMENTS, CONTROLLING THE MARKING OF AN INDEX SLIP, AND SIMILAR OPERATIONS. THE TRANSCRIBING UNIT HAS AN ASSOCIATED HEAD SET AND FOOT CONTROL AND VARIOUS OPERATING CONTROLS, PROVIDED ON THE FRONT OF THE TRANSCRIBING UNIT. TRANSCRIBING OPERATIONS ARE UNDER CONTROL OF A FOOT PEDAL AND INCLUDER STARTING AND STOPPING OF THE BELT MOVEMENT, A SYMMETRICAL FORWARD AND REVERSE REVIEW WHICH IS REPEATABLE, AND OTHER OPERATIONS REQUIRED FOR TRANSCRIBING. EACH UNIT IS PROVIDED WITH INDEPENDENT MECHANISMS FOR RESTORING THE SOUND TRANSDUCER WHEN A BELT IS UNLOADED, CONTROL MEANS FOR ESTABLISHING ONE INITIAL MARGIN DURING RECORDING AND ANOTHER INITIAL MARGIN DURING PLAYBACK, AND MEANS FOR RAPIDLY ALIGNING THE SOUND HEAD IN RELATION TO THE RECORD MEDIA FOLLOWING A MANUAL SCAN OPERATION.
