SonicRead helps you to to extract data from your Polar heart rate monitor using Soniclink. Follow the below stated steps to do so. * Make sure you are in a quiet environment to prevent glitches in the audio signal. * Enable the microphone signal in the Volume Control program of your Operating System. * Press the Start button in SonicRead. * Hold your watch near the microphone. * Select "Connect" in the menu of your Polar. * SonicRead should indicate that it started processing SonicLink data, and will update the progress bar. * When done, press the Save button and save the hsr file to the location you wish * Use SportsTracker (http://www.saring.de/sportstracker/index.html) to view the data. If SonicRead doesn't recognize the signal, check the microphone volume: The dB meter bar should be around 20-30% full when picking up background noise. If you make noise, like for example snapping your finger, the progress bar indicator should rise to 80-90%, and will possible indicate that the audio signal clipped.
