Using the POLAR® Equipment

The Precor Heart Rate System has many unique features. Before you use the POLAR® chest strap, please study this section thoroughly.

Important: If you do not use the Precor Heart Rate Option according to the guide- lines found in this manual, you could jeopardize the accuracy of your heart rate readings or void the manufacturer’s limited warranty.

Wearing the POLAR® Chest Strap

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 POLAR® chest strap. 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:

1. Adjust the tightness of the chest strap by sliding the buckle along the strap.

2.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 19.

3. Remove the strap from around your chest and carefully dampen the electrode strips with tap water as shown in Diagram 20 or use the Precor spray. Do not use deionized water. To function properly, the electrodes need the salts and minerals found in non-purified water. During your workout, your perspiration keeps the electrodes moist.

4. 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 21.

Note: The chest strap transmitter has a one- year warranty.

With the proper adjustment of the chest strap, you are ready to begin using the Heart Rate interactive capabilities on your treadmill.

CAUTION: Do not use abrasive cleaner on the strap. Do not immerse any part of the chest strap. Do not spray or pour liquids on any part of the equipment.

Storing the POLAR® Chest Strap

Store the chest strap transmitter in a place where dust and dirt cannot accumulate on it such as, a closet or drawer. Be sure to keep the chest strap protected from extremes in temperature. Do not store it in an area that may be exposed to tempera- tures below 32 degrees Fahrenheit.
