Precor 9.21 Treadmill User Manual


 
Owner’s Manual: Programs 24
Note: To monitor your heart rate and use the HRC
Program, you must purchase and install the optional heart
rate receiver. While exercising, you need to wear the chest
strap.
Warm-up Period
The treadmill provides a 3-minute, warm-up period. During
this time, you may change the incline or speed.
Note: If your heart rate moves into the target heart rate
zone during the 3-minute, warm-up period, the warm-up
period ends and the Heart Rate Control Program begins.
Using the HRC Program
When the warm-up period concludes,
The treadmill automatically adjusts the incline to keep
your heart rate at the selected target. Pressing the
INCLINE arrow keys no longer affects the incline lift, but
does change the target heart rate.
You can change the target heart rate or speed of the
running belt, but doing so affects the unit’s ability to
maintain your target heart rate in the preferred zone. It
takes time for the treadmill to readjust the incline so that
your heart rate remains on target.
Note: If you are having difficulty with the heart rate
features, refer to Advanced Programming and
Troubleshooting.
