ABSTRACT:
A central dictation system for recording dictation or other messages. The messages are recorded on interchangeable record members such as conventional recording tape cassettes, and the present system is operable to substitute a new cassette for a cassette containing one or more recorded messages, either upon receipt of a signal indicating termination of message recording or upon the occurrence of certain other events. A signal is provided when only a predetermined amount of recording time remains on a cassette, notifying the user that substitution of a new cassette will occur after a predetermined amount of time elapses. Another signal is provided during the cassette substitution cycle to prevent message dictation until the new cassette is positioned to receive dictation. The cassette central dictation system of the present invention is usable in combination with one or more dictate stations and in conjunction with a system including another central message recording apparatus, and circuitry is provided to enable priority selection of the cassette central dictation system.
