Hi!

I have a Polar FT4, when I was working out it starting saying to check the strap, which it's done before and once the strap was adjusted worked fine. Only this time it wouldn't. I washed it thinking this would help, as it has when i've had similar problems.

But now it's showing me a starting heart rate of anywhere between 200-225. I don't know what else to try, has anyone had similar problems?
