this in mind and take time to read the following guidelines:
• Handlethe PrecorHeart RateOption with care.Do notdrop theequipment.
It might damage the transmitter and you could void the manufacturer’s
limited warranty.
• Donotplacethecheststrapnearstrongelectromagneticradiationsources.
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
providingenoughmoisturethroughyourperspirationtokeeptheelectrodes
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
