Contact Heart Rate
CHAPTER ONE: RIDING YOUR BIKE
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.
A Note on CHR Accuracy
CHR monitoring may be a bit less
accurate than a chest strap, since
the heart rate signals are much
stronger at the chest.
About 5% of the population cannot
be picked up by any CHR system.
This is because their heart is po-
sitioned in a more up-and-down
manner in their chest, as opposed
to leaning over to one side.
