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 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:
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.
