I've had a polar f7 hrm for almost a year now and it's been great,, however it's just stopped working, not reading the heart rate and calculating calories burned. The watch itself is working fine but not the chest strap.
Shoud I try changing the battery? I can't open the compartment so would have to take it to a watch shop to be done?
Any advice?
