User’s Reference Manual: Heart Rate Features 5
Heart Rate Features
Heart rate and SmartRate ® features are available when you wear the
chest strap or grasp both touch-sensitive handlebar grips. When a
heartbeat is detected, the Heart Rate display shows your heart rate
and the SmartRate LED pulses and indicates your target zone.
Guidelines
Read the following before using the heart rate feature.
• Consult your physician before engaging in any vigorous exercise.
Do not use the heart rate features until authorized by your
physician.
• Know your heart rate (pulse) and your physician-recommended
heart rate target zone. Individual heart rates vary according to
several physiological factors and may not correspond directly
with Diagram 3.
Diagram 3: Heart rate target zones
• The calculation used for the heart rate target zone is:
Low range: (220 minus your age) multiplied by 55%
High range: (220 minus your age) multiplied by 85%
