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, if your age has been entered, the SmartRate LED pulses and 
indicates your target zone.
Important Use and Safety Information
Read the following before using the heart rate or SmartRate features.
Consult your physician before engaging in any vigorous exercise. 
Do not use the heart rate programs until authorized by your 
physician.
Know your heart rate 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.
The calculation used for the heart rate target zone is:
(220 minus your age) multiplied by a percent. 
Refer to Table 1 in Using SmartRate
