Precor 5.31 - Manual (Page 19)

Owner’s Manual: Heart Rate Features 17
Table 1 shows the percents used in calculating the heart rate
target zones. While your heart rate remains within these
zones, the corresponding light blinks 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 strides per minute, adjust
the CrossRamp, or resistance to return your heart rate to
your physician-recommended target zone.
