I got a used PowerTap for my birthday last year and couldn’t get the heart rate monitor working. I tried replacing the battery, but that didn’t help. Well this year I got a new heart rate monitor for my birthday, and guess what. That doesn’t work either. I’ve always used saliva on the electrode pads for my past Polar monitors and haven’t had any problems. Does anyone out there use the cream you can get from those online stores? Or even better had a similar problem and was resolved by taking certain steps. Please help!!!
