I have had my blaze for several months and it's been great and fairly accurate. However, a few days ago I noticed it wasn't always picking up the HR. I cleaned it as described in the literature that comes with it and have tried wearing it on the inside, outside, of wrist, etc. I have changed from heartrate on to auto and back. I have tried resetting the blaze and nothing works. Now it's never picking up heart rate. The front screen always says 70 no matter what I am doing. If i put it in exercise mode for a workout, it just says --- Is there a way to fix this?
