Contact Heart Rate Use
RIDING YOUR BIKE
Z8 Bike Owner’s Guide

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,
the heart rate LED will flash in time
with your heart beat. During this time,
the system is analyzing and locking in
your heart rate. Within about 10
seconds, your digital heart rate in
beats per minute (bpm) should be
displayed.

HEART RATE
(CHR)
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.
The Z8 Bike uses the most
advanced CHR system
available. It converts your
heart rate waveform to a
digital signal, then analyzes
the digitized waveform to
pick out the electrocardio-
gram shape and thus the
heart rate.
About 5% of the population
cannot be picked up by any
CHR system. This is
because their heart is posi-
tioned in a more up-and-
down manner in their
chest, as opposed to leaning
over to one side.
