TESTING THE HEART RATE DISPLAY
If you have purchased the optional POLAR
®
chest strap, verify that the heart rate
display is operational before customers begin using the machine.
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 some people, because of body
chemistry or erratic heart beats cannot use the heart rate feature on the EFX.

1. Wet the electrode strips on the POLAR
®
chest strap and wrap it around your
chest as shown in Diagram 23. Adjust the strap so that it maintains a snug fit.
2. Hold onto the stationary handrail and step onto the foot pedals.
3. Begin pedaling and maintain a stride rate above 40 strides per minute. The
Precor banner will appear on the display.
4. Wait five to ten seconds. A number indicating your heart rate (beats per minute)
should appear in the display. Three dashes appear (— — —) if a heart beat is
detected, but interference is occurring. Try readjusting the chest strap.
5. If the heart rate display appears, the cables are properly connected and the
heart rate feature can be a viable part of a user’s workout.
6. If the heart rate display does not appear, press Reset to return to the Precor
banner and then, ask someone else to try steps 2 through 4. If no heart rate
number appears, reconnect the cables at the front of the base tube. Follow
steps 1 through 4, again.
If a heart rate cannot be detected, refer to
