BLOOD PRESSURE MACHINE WOES

Last year I bought my mother-in-law a wrist blood pressure machine. So she put it up but found it the other day. After putting batteries in it she still could not get it to work. She was telling me how her and my sister-in-law worked with it and it still would not work. We can't get it off of 140/80. I looked at it and started laughing. Ok. do you have new batteries in it. Yes. Let me take a look at it. I knew when I saw it what was wrong with it. I needed a good laugh as I had been worried all day long. So I got it and looked at it and started laughing again. She could not understand what I was laughing about. I showed her the machine and of course it said 140/80. It just won't go off of that number she said. Ok give me a minute. I started peeling the plastic off of the front of the machine. Now look at it no numbers. What was wrong with it they had put a plastic covering over the face and it said 140/80. How many items today do we buy that has that plastic over the front to protect it. Almost ever electronic item does. So if you get something with it on it just peel it off. I know the clocks are like that and the tape recorders and even the phones. Sometimes the plastic is hard to peel off but just keep working with it.
