SUPPLYING POWER TO THE EFX534i
The EFX does not require an electrical power connection. It has an internal battery
that is recharged every time a user works out for a reasonable period of time. A
pedaling speed above 40 strides per minute must be maintained for several seconds
before the Precor banner appears on the display. Once the banner appears, the user
can press QuickStart or Enter to begin working out. For more information, refer to
page 36,
Exercising on the EFX
.
TESTING THE HEART RATE DISPLAY
If you have purchased the optional 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 sig-
nal 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. To
purchase a chest strap, refer to
Obtaining Service
on page 7.
1. Wet the back of the chest strap and wrap it around your chest as shown in
Diagram 21. 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
Obtaining Service
on page 7.
