My auntie has been nusing an AT&T "Tapeless Digital Answering System 1715" which does not seem to function properly anymore. When I try to set it up - after replacing the battery on the phone - the following happen: there is a constant rapid beeping, and the display shows the letters "fO." What does this mean? Please advise me. thank you very much. Joan
