To test your heart rate:
1. Select a workout and press GO or ENTER.
2. Grasp the heart rate sensors with both hands. A
blinking heart indicator appears while the
equipment reads your heart rate. After a few
seconds, the console displays your heart rate in
beats per minute and shows it on the SmartRate
scale. The labels next to the SmartRate scale
indicate the zone where your heart rate is currently
operating:
–
Warm Up
–
Fat Burn (weight loss)
–
Cardio
–
High
Measuring Your Heart Rate
Note: In the Basic Heart Rate Control workout, the GO
key is deactivated. The equipment needs to know your
age to set an accurate target heart rate, so you must
either enter it or select a user account before you start
the Basic Heart Rate Control workout.
