Polar CS200CAD


Leafy Cheshire
Hi all

I have the Polar CS200CAD. Never had any problems but for a few days now it has been picking up my heart rate (the heart symbol is flashing - sometimes a little irregularly) but not displaying any number for my HR.

Does anyone have any ideas? I would be very grateful!


I've experienced this, and probably every other owner. It's down to the heart strap's ability to "eat" batteries. Pop a new one in and everything will be back to normal.

It doesn't seem to matter which make battery you replace the old one with. Some last for ages and others four to six months. It's a lottery.

Hope this helps L?
