Owner’s 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. All 10 LEDs may light during a workout. When the
treadmill 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 during the setup phase of your exercise session.
The 10 LEDs in the SmartRate display are color-coded. A
pulsating orange LED indicates you are outside the
recommended heart rate target zone. Green LEDs indicate
when you are exercising within the recommended fat burn or
cardio fitness zones.
Table 1 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 Table 1, you can understand the relation-
ship 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 pace or adjust the incline
to return your heart rate to your physician-recommended
target zone.
