Abstract
A reset system for a telephone answering machine which, in the event of a power failure, or should the telephone answering machine be disconnected from the power mains, will reset the telephone answering machine when power is restored to the condition it was in just prior to the power failure. In a specific embodiment to be described, when power is restored, an incoming message magnetic tape is set to rewind for a selected time interval (for example, 2 to 3 seconds), and the number of pulses generated by the magnetic tape mechanism during that period are examined. If the number of pulses exceeds a predetermined minimum, it is assumed that there are incoming messages recorded on the tape, and the tape is returned to the position it occupied prior to rewind. In addition, control and indicator mechanisms within the system are set to the state they were in just prior to the power failure.
