I bought the heart rate monitor HRM3-SS a few years ago and the batteries have died, how do I replace these? I couldn’t find the batteries suggested anywhere online.
I emailed a month ago so hopefully the forum helps. Kind regards.

There will be 4 very small and likely very tight screws on the back. Remove them carefully.
