Troubleshooting Heart Rate

Table 1 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 user maintains a minimum of 20 RPM. A user must also wear the chest strap on the C842i or grasp both touch-sensitive handlebar grips on the C846i.

Note: To conduct electrical impulses from a user’s heart, both touch-sensitive handlebar grips (C846i) 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 heart rate feature. A chest strap may provide better results.
