Using the Precor Heart Rate Option

The Precor Heart Rate Interactive System has many unique features. When you use the Precor Heart Rate Option and have the optional heart rate receiver installed in the electronic console, your heart rate can appear on the display. The Smart Rate and Heart Rate displays simplify the correla- tion between heart rate and exercise. You don’t have to stop concentrating on your workout to find your pulse anymore. It is displayed right in front of you. When you use the Heart Rate Control Course, the EFX software monitors and maintains your heart rate in the target zone best suited for your specific needs.

When you maintain your heart rate between 70% and 85% of your maximum aerobic heart

rate, you are improving your overall cardiovascular/cardiorespiratory fitness level. If you maintain your heart rate between 55% and 70% of your maximum aerobic heart rate, you are burning enough calories that, when continued on a regular basis for 30 minutes or more, provides the greatest fat-burning (weight loss) benefits. Before you use the chest strap transmitter, please study this section thoroughly. Included in this section are the following:

•	wearing the chest strap transmitter	•	using the Heart Rate Control Course (HRC)
•	utilizing the heart rate interactive system	•	correcting inconsistent heart rate readings

Important: If you do not use the Precor Heart Rate Option and the optional heart rate receiver according to the guidelines found in this manual, you could jeopardize the accuracy of your heart rate readings or void the Precor limited warranty.

Wearing the Chest Strap Transmitter

The Precor Heart Rate Option is a completely wireless system. A built-in receiver displays continual feedback about your heart rate when you wear the transmitter strap around your chest. No bulky wires or cables interfere with your movements.

The wireless chest strap contains the electrodes that transmit your heart rate (pulse) to the receiver. To get an accurate reading, the electrodes need to be moist and in direct contact with your skin. Be sure to wear the chest strap underneath your clothing.

Take the following steps to put on the chest strap:

With the proper adjustment of the chest strap, you are ready to begin using the Precor Heart Rate Option.

1.Determine the length of the strap by wrapping it around your chest. Without stretching the strap, check the distance between the two ends of the strap. For a snug fit, the ends of the strap should be about 6 inches (15 cm) apart. See Diagram 9. Adjust the tightness of the chest strap by sliding the buckle along the strap.

2.Remove the strap from around your chest and carefully dampen the electrode strips with the electrolyte spray or tap water as shown in Diagram 10. Do not use deionized water. To function properly, the electrodes need the salts and minerals found in non-purified water. Once you begin your workout, your perspiration keeps the electrodes moist.

3.Buckle the strap around your chest. The strap should feel snug, not restrictive. Make sure that the transmitter lies horizontally across your chest and is centered in the middle of your chest. See Diagram 11.

Note: The chest strap transmitter has a one-year warranty and contains a replaceable battery. To change the battery, refer to the section titled, Changing the Battery in the Chest Strap on page 22.
