Contact Heart Rate
CHAPTER ONE: BASIC OPERATION
Contact
Heart Rate
(CHR)
The contact heart rate (CHR) system lets you monitor your heart
rate without wearing a strap.
Gently grasp the contact heart rate pads.
When the system detects your hands, the Heart Rate label will start
flashing 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.
Important: The CHR System should only be used at speeds of
4 mph or lower. Above this speed the CHR accuracy is unavoidably
unreliable due to large muscle movements.
1. Exercise with smooth body
motions.
2. Breathe smoothly and
regularly, and avoid talking.
(Talking will cause
unrepresentative heart rate
spikes of 5 to 10 bpm.)
3. Grip the pads lightly, not
tightly.
4. Make sure your hands are
clean, free of both dirt and hand
lotions.
When using a Heart Rate Control
workout, it is best to use chest strap monitoring. These workouts
work best with the extra accuracy gained from a chest-contact heart
rate monitoring system.

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 positioned in a
more up-and-down manner
in their chest, as opposed to
leaning over to one side.
