Heart Rate Features
Heart rate and SmartRate
®
features are available when you wear the
chest strap. When a heartbeat is detected, a number (representing
your heart rate) appears in the display when the HEART RATE LED
is lit. The SmartRate LED pulses and indicates your target zone.
The chest strap is an optional purchase item for the C842i cycle.
Check with the club or facility manager to see if a chest strap is
available.
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.
