User’s Reference Manual: Heart Rate Features 6
Using SmartRate
The SmartRate feature helps you monitor and maintain your heart rate
in the target zone best suited to your specific needs. When the EFX
detects a heart rate, 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.
If you were not prompted for your age during program selection,
press the OPTIONS key and enter your weight and age. Refer to
Addressing Your Weight and Age.
The 10 LEDs in the SmartRate display are color-coded. Pulsating
orange LEDs indicate you are exercising outside the recommended
heart rate target zone. Green LEDs indicate when you are exercising
within the recommended fat burn or cardio fitness zones.
Table1 shows the percents used in calculating the heart rate target
zones. While your heart rate remains within these zones, the
corresponding lights blink and provide a visual cue.
The calculation used to determine your maximum aerobic heart rate is
(220 minus your age). When you multiply it by the percent indicated in
Table1, you can understand the relationship between the pulsating
LED and your target heart rate.
CAUTION: Your heart rate should never exceed 85% of your
maximum aerobic heart rate or go above PEAK. If it does,
immediately reduce your stride rate, or adjust the resistance, or
ramp incline (EFX576i, EFX546i) to return your heart rate to your
physician-recommended target zone.
Table 1. Heart rate target zones and SmartRate LEDs
The SmartRate indicator lights do not appear when:
• You do not wear or improperly position the chest strap. Or, you fail
to grasp both touch-sensitive handrail grips for five to ten seconds.
• You do not enter your age before or 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. The LEDs do not light in the SmartRate
display because the appropriate calculations have not been made.
Note: You can remedy this situation by pressing the OPTIONS
key and entering your weight and age.
Refer to Fitness Tools on the Precor web site www.precor.com for
exercise suggestions and routines.
