Owner’s Manual: Heart Rate Features 10
Heart Rate Features
Heart rate and SmartRate® features are available when the
heart rate receiver is installed in the display console and you
wear a chest strap. When a heart beat is detected, the heart
rate display shows your heart rate and the SmartRate LED
pulses and indicates your target zone.
Note: The heart rate receiver and chest strap are optional
purchase items for the EFX5.17i and EFX5.19.
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 6.
