Owner’s Manual: Heart Rate Features 13
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 bar blinks and
indicates your current heart rate zone. All 10 bars may
appear during an exercise session.
Important: To use the SmartRate feature, you must
choose a program and enter your age during the setup
phase of your exercise session.
Table 1 shows the percents used in calculating the heart
rate target zones. While your heart rate remains within
these zones, the corresponding bar blinks and provides 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
relationship between the blinking bar and your target heart
rate.
CAUTION: Your heart rate should never exceed 87% of
your maximum aerobic heart rate or go above PEAK. If it
does, immediately slow down and adjust the ramp
incline or resistance to return your heart rate to your
physician-recommended target zone.

default age of 35 years is used for heart rate
calculations.
