Troubleshooting Heart Rate
Table 6 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
EFX is turned ON. You must also wear the chest strap.
Table 6. Erratic heart rate readings
Note: To conduct electrical impulses from a user’s heart, the
electrode strips on the chest strap must be in contact with
the user’s skin. 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.
