Anyone experiencing this?
Press the “mode” button on the watch unit and check the display to see if the device responds.

It was working really well until earlier this week when the battery died, so I replaced it. New battery died on the first work out. So I replaced it. Same result. Googling, it seems this is a fairly common thing, once the battery needs lkkHmc2.
