Owner’s Manual: Heart Rate Features 14
Using the Touch-Sensitive Grips
While exercising on the EFX, you must grasp both touch-
sensitive grips for a minimum of five to ten seconds to
transmit your heart rate to the display. Refer to Diagram 6.
Diagram 6: Touch-sensitive grips
Usually, the concentration of salts in a person's
perspiration provides enough conductivity to transmit a
signal to the receiver inside the display console. However,
some people, because of body chemistry or erratic heart
beats cannot use the touch-sensitive heart rate feature on
the EFX.
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
relation-ship 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 reduce your strides per minute and
adjust the CrossRamp or resistance to return your heart
rate to your physician-recommended target zone.
