ABSTRACT:
A reset system for a telephone answering machine which, in the event of power failure, or disconnection from the power source, will reset the telephone answering machine when power is restored to the condition it was in prior to the power failure. The system is applicable to both single tape machines in which the outgoing announcement and incoming messages are all recorded on one magnetic tape, and dual tape machines in which the outgoing announcements are recorded on one magnetic tape and the incoming messages are recorded on a second magnetic tape. The system of the invention serves to determine whether there were incoming messages on the incoming message tape when the power failed and if so, the end of the last recorded incoming message is located so that when power is restored the incoming message tape can be set to the same position it was in when power was lost.
