Troubleshooting Heart Rate

The following table 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. A user must wear the chest strap or grasp both touch-sensitive grips.

Note: To conduct electrical impulses from a user’s heart, both touch-sensitive 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 touch-sensitive grips. A chest strap may provide better results.
