Gazelle

Hi,

I have a Gazelle Edge that I use for 30 minutes. It keeps track of my calories for me. After recharging my batteries a few days ago it started tracking my calories in the low to mid 300s! Typically it would track me at 140-180 calories burned. I don't know if the wires are crossed or what but I would like to know what is accurate. A few times, before I recharged the batteries it was tracking me at 70 calories burned, which I knew was wrong! It is really irritating me! Suggestions? Any one else have a Gazelle Edge?
