WARNING—
DANGER—To reduce the risk of electrical shock, always unplug the EFX544
from the electrical outlet immediately after using and before clean-

To reduce the risk of burns, fire, electric shock, or injury to persons,
take the following precautions:
Connect the EFX544 to a properly grounded outlet only. See
Grounding Instructions .

COMMERCIAL PRODUCTS DIVISION
Grounding Instructions
The EFX544 must be grounded. If it should malfunction or break down,
grounding provides a path of least resistance for electric current which reduces
the risk of electrical shock. The EFX544 is equipped with a cord having an
equipment-grounding conductor and a grounding plug. The plug must be
plugged into an appropriate outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
DANGER
Improper connection of the equipment-grounding conductor can result in a risk
of electric shock. Check with a qualified electrician or serviceman if you are in
doubt as to whether the unit is properly grounded. Do not modify the plug
provided with the EFX—if it will not fit the outlet, have a proper outlet installed
by a qualified technician.
120VUNITSDESIGNATEDFORU.S.MARKETS
The EFX544 is for use on a nominal 120-volt circuit and has a grounding plug
that looks like the plug as illustrated. Make sure that the unit is connected to an
outlethavingthesameconfigurationastheplug.Noadaptershouldbeusedwith
this product.

240VUNITSDESIGNATEDFORU.S.MARKETS
The EFX544 is for use on a circuit having a nominal rating more than 120 volts
and is factory-equipped with a specific power supply cord to permit connection
to a proper electric circuit. Make sure that the EFX544 is connected to an outlet
having the same configuration as the plug. No adapter should be used with this
product. If the EFX544 must be reconnected for use on a different type of
electrical circuit, the reconnection should be made by qualified service person-
nel.

Information Regarding International Use
FCC Communications Commission, part 15
The EFX544 has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference in a residential
installation. The EFX544 generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the owner’s manual
instructions, may cause harmful interference to radio communications. How-
ever, there is no guarantee that interference will not occur in a particular
installation.IftheEFX544doescauseharmfulinterferencetoradioortelevision

• Completely assemble the EFX544 before using it. Check the unit before
each use. Do not continue to operate the EFX544 when it is not working
properly. Return the unit to a service center for examination and repair.
• Keep all electrical components, such as the power cable, and ON/OFF
switch, away from water or other liquids to prevent shock. Do not set
anythingonthecasingorelectronicconsole.Neverplaceliquidsonanypart
of the EFX544.
• Assembleandoperate theEFX544on asolid, levelsurface.Locate theunit
at least 4 feet from walls or furniture.
• Wear proper exercise clothing and shoes for your workout—no loose
clothing. Do not wear shoes with heels or leather soles. Check the soles of
your shoes and remove any dirt. Tie long hair back.
• KeepalllooseclothingandtowelsawayfromtheEFX544.Keephandsaway

ThePrecor Heart Rate Optionwas created and designedexclusively 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.
Theequipmentisextremelysensitive—youshouldusetheheartrateoptionwith
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

• Donotusethecheststrapifyouaretakinganymedicationorhaveacardiac

electrical impulses from the cardiac pacemaker.
• Stretchingor 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
inaccurateheartratereadings.Witheveryuse,checkthestrapforexcessive
