True Fitness Touchscreen Elliptical Owner's Manual page 29

TRUE's HRC workouts allow the ESX Touchscreen to monitor
your relative exercise intensity by way of your heart rate, and
automatically adjust the workload to keep you at your target
heart rate and thus your desired exercise intensity.
Your heart rate is a good measure of your body's exercise stress
level. It reflects differences in your physical condition, how tired
you are, the comfort of the workout environment, even your diet
and emotional state. Using heart rate to control workload takes
the guesswork out of your workout settings.
Consult your physician before using HRC workouts for advice
on selecting a target heart rate range. Also, it is important to use
the ESX Touchscreen for several workouts in the manual mode
while monitoring your heart rate. Compare your heart rate with
how you feel to ensure your safety and comfort.
See Appendix A for a chart that will help you select a target
heart rate.
You should wear a heart rate monitoring chest strap to use HRC.
See the "Heart Rate Monitoring" section in Chapter 1 for a
guide to proper usage. It is not recommended that you use the
contact heart rate system for HRC workouts.
