Bontrager HR Chest Strap

I have the Bontrager Node 2 Computer, but for the life of me I cannot get the the HR to work. The sensor within the conputer is turned ON and I have changed the battery in the strap, moved the strap around a bit, and applied a little spit to ensure it was moist. Does anyone have any ideas that I can try?

thanks,

Well, you can disreguard this. All I needed to do was to profess my ignorance publicly and I figured it out...with the help of a Google thread I had not found before. These senior moments are a PITA.
