About 2 months ago, I got up in the morning, went into the living room and turned on the TV to watch the news. I was sitting in my chair and heard a beeping noise and then it stopped. I got up to try to find it and could not locate the source. I checked all the alarms and batteries and nothing. This went on every morning, it got to the point it was driving me crazy (didn't have to drive far). By the time I got up to locate the beeping, it stopped, 5 beeps then nothing again until the next morning.
Usually, I get up first and my DW follows about 45 minutes to 1 hour later. One morning, she got up with me and yes, the beeping went off again. I said this is driving me nuts, she said, it's the new coffee maker, it beeps 5 times to let you know the coffee is done!
