User's Reference Manual: Heart Rate Features 15
Using SmartRate
The SmartRate feature helps you monitor and maintain your heart
rate in the target zone best suited to your specific needs. When a
heart rate signal is detected, a single LED blinks and indicates the
zone that your heart rate is in.
Important: To use the SmartRate feature, you must enter your age
during program selection. Refer to Selecting a Program .
The following table shows the percents used in calculating the
heart rate target zones. While your heart rate remains within these
zones, the corresponding light blinks and provides a visual cue.
CAUTION: Your heart rate should never exceed 85% of your
maximum aerobic heart rate or go above PEAK. If it does,
immediately reduce the intensity of your workout to return your
heart rate to your physician-recommended target zone.
Table 1. Heart rate target zones and SmartRate LEDs
Heart Rate Zone

62 to 69 Third FAT BURN

The SmartRate indicator lights do not blink when:
 You do not wear or improperly position the chest strap. Or, you
fail to grasp both touch-sensitive grips for five to ten seconds.
 You do not enter your age during an exercise session.
For example, pressing QUICKSTART at the Precor banner
causes the Manual Program to begin. Your age has not been
entered and is considered a null value. Your heart rate will
appear in the HEART RATE display when you hold onto the
touch-sensitive grips or wear a chest strap, but none of the
SmartRate LEDs blink because the appropriate calculations
have not been made.
Note: You can remedy this situation by choosing a program
using one of the PROGRAMS keys and entering your time,
weight, and age.
