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:
• Handle the Precor Heart Rate Option with care. 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 that is being transmitted to the receiver
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 EFX544.
• Keep the equipment dry. Although the chest strap should not be immersed
in water, wetting the electrodes and your chest will improve the initial
performance. Note that perspiration 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 continue to 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. See
Correcting Inconsistent Heart Rate Readings
on page 21.
• 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 and replace it if necessary. See
Obtaining Service
on the inside front
cover.
Precor exercise equipment is designed for your enjoyment. By following the
above precautions and using good common sense, you will have many safe and
pleasurable hours of healthful exercise with your Precor EFX544.
