New Balance N4 HRM

So, I have the N4 and I used it today when I went to work. I ride my bike 5 miles every day to work & then another 5 miles back. Well, I checked my hrm to see how many calories I'd burned once I'd gotten to work, and it said 75.... I don't think that's right. lol Then, on my way back home later on, it still said 75 & never changed. How in the world do I get this thing to work????
