Actually, finally figured it, boy do I feel stupid. I disconnected battery, then reconnected, still got the beep. Then went back and disconnected the battery, and the sound stayed on - realized it was a battery operated recorder, the lever must have moved it was sounding for the end of the tape. The good news, even though the battery was disconnected for several seconds, I did not have to reprogram the radio settings or window auto up.
Funny story! I also haven't heard anyone refer to an actual real-life tape recorder in quite a while!
