Complete several outdoor runs with GPS and your connected
HRM 600,
HRM-Fit™, or
HRM-Pro™ series accessory. It's important that your outdoor range of paces matches your range of paces on the treadmill.
If your run includes sand or deep snow, go to the sensor settings, and turn off Auto Calibrate.
If you previously connected a compatible foot pod using
ANT+® technology, set the foot pod status to Off, or remove it from the list of connected sensors.
