Troubleshooting Heart Rate

Table 4 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.

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.
