Anyone have a Nordictrack machine that tracks HR via Polar?

I just set up my new C900 Pro treadmill. It comes with a chest strap from polar and reads the HR. I have a Polar FT7 too. My question is, is there a way to set my stats in the treadmill so the calorie burn is accurate? I couldn't find a way to do it, so I ended up wearing my watch too, and the calorie burn was about 50 calories more for the 23 minutes I worked out. I can continue wearing my watch, but I'm pretty disappointed that there's no apparent way to change the height/weight on the machine itself.
