HEART RATE TROUBLESHOOTING TIPS
A few easy steps can be taken before you need to call customer support regard-
ing heart rate problems. One of the first things to do is verify the following:
❑
A POLAR
®
chest strap is being worn properly by the user during a workout.
Or, the user is placing both hands on metal grips found on the handlebars.
❑
The user is pedaling above 20 RPM.
❑
The user is working out in a selected a course. (The Heart Rate feature is
activated when a course profile appears.) Note that if the user presses
QUICKSTART to access a course, the SmartRate and heart rate features will
not appear.
Other aspects of the heart rate option are discussed below:
Detecting a Heart Beat
It may take several seconds for the heart rate receiver to detect a number of
valid
heartbeats. Once it does, the user’s heart rate is displayed when the Heart Rate
indicator (LED) is lit during the scanning process.
If “— — —” appears when the Heart Rate indicator (LED) is lit and all the previ-
ously discussed steps have been taken, then you need to do the following:
Touch-sensitive heart rate
•
to conduct electrical impulses from a user’s heart, both touch-sensitive grips
(metal strips) must be in contact with the user’s skin. Usually, the concentra-
tion of salts in a person’s perspiration provides enough conductivity to trans-
mit a signal to the receiver in the display console. However some people,
because of body chemistry or erratic heartbeats, cannot use the heart rate
touch-sensitive feature on the C846. A POLAR
®
chest strap may provide
better results. Refer to
Obtaining Service on page 7.
POLAR chest strap
•
Make sure that the electrodes on the chest strap are moist and placed prop-
erly against the skin. Sometimes, due to body chemistry, the chest strap
cannot successfully detect and transmit a heart rate. If this occurs, use the
electrolyte spray that accompanies the Precor Heart Rate Option package.
Follow the directions on the bottle. After spraying the electrode strips on the
chest strap, check to be sure that the strap is comfortably tight around the
chest and centered in the middle of the user’s chest.
•
Another possibility which can cause erratic readings is that the chest strap’s
battery may be dead. To purchase a new chest strap, refer to
