Heart Rate Monitor
To collect heart rate information, the 'Heart Rate' option must be enabled during
initialization and a compatible Bluetooth® wireless heart rate monitor is required.
Unsnap the heart rate transmitter from the chest strap, position the transmitter in
the center of the sternum, and snap back into place. Adjust the strap so that it is
secure across the breast bone. The wGT3X-BT will automatically begin collecting
heart rate information when in range of the chest strap.
Note: Application of a water-based lubricant between the skin and transmitter can
improve conductivity and reliability of the heart rate signal.
