Precor LOW-IMPACT TREADMILLS 9.33 Owner's Manual page 17

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 pace or adjust the incline
to return your heart rate to your physician-recommended
target zone.
