Precor EFX 5.21i - Manual (Page 14)

Owner’s Manual: Heart Rate Features 12
For the ideal weight loss range, the first, second, and third
SmartRate LEDs are lit and the fourth LED blinks. If you are
working out in the cardiovascular zone, the fifth or sixth LED
should be blinking. Refer to Table 1.
Table 1. Heart rate target zones and SmartRate LEDs
CAUTION: Your heart rate should never exceed 85% of
your maximum aerobic heart rate. If it does, the seventh
SmartRate LED begins to blink. Immediately reduce your
strides per minute, resistance, or adjust the ramp incline
to return your heart rate to its target zone.
Exercise to Your Target Heart Rate
The EFX includes a program that lets you exercise based on
a specified heart rate. You set your target heart rate at the
beginning. As you exercise, the Heart Rate program monitors
your heart rate and automatically maintains it within a few
beats per minutes (bpm) of your selected target. Your actual
heart rate (pulse) appears in the display when the HEART
RATE LED is lit.
To use this program, select HRC. You must also wear the
chest strap so the program can monitor your heart rate
throughout the workout. For more information, refer to Heart
Rate Control (HRC) Program.
