Omron electronic sphygmomanometer was bought in June last year at 5438+065438+ 10. I used it several times, but it was inconvenient to use it in cold weather, so I wrapped it up and stored it. Now come out and use it, I think I forgot to take it out when I put the battery in. The battery has been dead for a long time. Try another battery.

It is possible that the battery leakage will make the metal electrode of the battery box rust and unable to conduct electricity, and it is not good to replace it with a new battery. Find a small file to repair the electrode, and then try to use a new battery.
