I'm got a garmin FR60 heart rate monitor watch for Xmas from my wife. I used it for a few rides and kept track of my calories burned. I have since purchased and installed a GSC10 sensor and have made a few rides with it. I have noticed my calories burned are a lot lower since installing the GSC10.

Does the FR60 only calculate calories when the GSC10 is measuring speed? If so is their a way to change this setting?
