Precor Heart Rate Option—Safety Guidelines
The Precor Heart Rate Option was created and designed exclusively for Precor
products. Before using this option, read and follow the instructions found in the
owner’s manual that accompanies your option kit or chest strap transmitter.
The equipment is extremely sensitive—you should use the heart rate option with
this in mind and take time to read the following guidelines:
• Do not drop the equipment. It might damage the transmitter and you could
void the manufacturer’s limited warranty.
• Do not place the chest strap near strong electromagnetic radiation sources.
Television sets, electric motors, radios, and high voltage power lines can
interfere with the heart rate signal and might affect the heart rate readings
that appear on the electronic console.
• Use only one chest strap at a time inside the range of the receiver. If the
receiver tries to process several signals simultaneously, an incorrect heart
rate reading could result. Be sure to keep any other transmitters at least 5
feet (1.5 meters) away from the receiver on your treadmill.
• The chest strap should not be immersed in water, however, wetting the
electrodes and your chest improves initial performance. Note that perspira-
tion on the chest strap during workouts is normal and actually enhances the
signal being sent from the chest strap’s transmitter.
• To conduct the electrical impulses from your heart, the chest strap’s
electrodes require a certain percentage of salts and minerals in the water
used to wet them. The electrodes transmit your heart rate reading as long
as they are in contact with your skin and your skin is providing enough
moisture through your perspiration to keep the electrodes wet. However, if
the concentration of salts in your perspiration is not high enough to conduct
electrical impulses and send them to the receiver, your heart rate reading will
appear erratic or not appear at all. Some people cannot use the heart rate
feature because they do not have the proper body chemistry.
Note: The spray in the option package may help increase the conductivity
of the chest strap electrodes. Use it as described in the option kit.
• Do not use the chest strap if you are taking any medication or have a cardiac
pacemaker. Inaccurate heart rate readings can occur due to medication or
electrical impulses from the cardiac pacemaker.
• Stretching or bending the electrode strips on the chest strap may cause the
strips to lose their conductivity. Handle the chest strap with care.
• After extensive use, the chest strap (transmitter) may wear out, causing
inaccurate heart rate readings. With every use, check the strap for excessive
wear. To replace it, see
