Need help with my polar FT4 HRM

derek2680

I have had my polar for about 4 months and have used it and love it. The last week it has not been working properly. It is still working and monitoring my HR fine, but once I am finished and hit the stop button to show the cals I burned and how long I worked out it just goes back to the original face and does not show my info. Anyone else ever have this problem and know how to fix it? I dont want to have to go back to relying on the machines for accurate cals burned. Thanks in advance.
