I just bought a Bontrager Node 1 which came with the actual display unit and the magnetic piece that fits to the spoke on the wheel. In addition, the salesman sold me the Cadence tranceiver (or whatever it's called--I guess its the part that attaches to the frame to read the magent). I followed the directions to pair them, but the computer cant see the Cadence. What am I doing wrong?? Their instructions are lacking in useful information. Any help is appreciated, Thanks.
