Contact Heart Rate
12
The contact heart rate system lets you monitor your heart rate
without wearing a strap.
Gently grasp the contact heart rate pads as shown below.
When the system detects your hands, a red heart will appear in
the Heart Rate field of the data display and will flash in time with
your heart beat. During this time, the system is analyzing and
locking in your heart rate. Within about 15 seconds, your digital
heart rate in beats per minute (bpm) should be displayed.
