Using the Precor Heart Rate Option
5
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 correlation
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 Course, the 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, Heart Rate
Course, or Weight Loss program, please study this section thoroughly. Included in this section are
the following:

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:
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 11. Adjust the tightness of the chest
strap by sliding the buckle along the strap.
2. Remove the strap from around your chest and dampen the
electrode strips with tap water as shown in Diagram 12 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. 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 13.
Note: The chest strap transmitter has a one-year warranty.
Some units contain a replaceable battery. To change the
battery, refer to
Changing the Battery in the Chest Strap
