Troubleshooting Heart Rate
Table4 may help you understand and troubleshoot erratic
heart rate readings.
Important: A heart rate can only be detected when the
Precor heart rate receiver is properly installed in the display
and the treadmill is turned ON. You must also wear the
chest strap or hold onto both touch-sensitive handrail grips.
Table 4. Erratic heart rate readings
Note: To conduct electrical impulses from a user’s heart,
both touch-sensitive handrail grips must be grasped firmly
for five to ten seconds. Usually, the concentration of salts in
a person’s perspiration provides enough conductivity to
transmit a signal to the receiver in the display console.
However, because of body chemistry or erratic heartbeats,
some people cannot use the heart rate feature. A chest strap
may provide better results. Refer to the QuickStart Card for
proper placement of the chest strap.
