Precor EFX 5.23, efx 5.25 manual Using the Touch-Sensitive Grips, Using SmartRate

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.
