UNDERSTANDING SMART RATE ON THE C964i
The C964i software incorporates the latest in cardiac monitoring to provide
Smart Rate
TM
—a visual aid that lets the user know what his or her heart rate is
at a glance. When the Precor Heart Rate Option chest strap is worn, the graph
on the display lights up with colored cells to indicate exercise intensity. A specific
percent of the user’s heart rate appears as a blinking cell within that zone.
Important: The Smart Rate blinking indicator light and the heart rate display only
appear when a receiver is installed in the electronic display and the chest strap
transmitter is used. If the Smart Rate lights appear, but do not blink, it means that
a receiver is installed, but the user is not wearing the chest strap transmitter or
it is not working properly. Refer to Obtaining Service on the inside front cover.
Smart Rate simplifies the correlation between heart rate and exercise. You don’t
have to stop concentrating on your workout to find your pulse anymore. Smart
Rate performs all the calculations for you and displays a graphic image of where
you are in your zone. Smart Rate uses your age and your maximum aerobic heart
rate to calculate a zone. The blinking cell symbolizes the percent at which your
heart rate is working and displays it in the cardiovascular or weight loss zone.
Using Smart Rate during a workout with any C964i program helps maximize the
user’s weight loss or cardiovascular fitness regimen. While a user works out in
a particular course, show him or her the Smart Rate display and change the
incline to position his or her heart rate in the desired Smart Rate zone.
Important: The Smart Rate indicator lights do not appear when you use the
QUICK START key.
When the heart rate is maintained between 70% and 85% of a person’s
maximum aerobic heart rate, overall improvement occurs to their cardiorespira-
tory fitness level. If a person maintains his or her heart rate between 55% and
70% of their maximum aerobic heart rate, he or she is burning enough calories
that, when continued on a regular basis for 30 minutes or more, provides
primarily fat-burning (weight loss) benefits.
