Heart Rate Control is precisely what it's name implies: The Smooth 9.3 reads your heart rate, and adjusts itself to keep you within a target range. Here's how it works:

The equipment has a heart rate receiver inside the console. You wear a wireless heart rate monitor/transmitter (like the one shown at right), which fastens around your upper abdominals. The wireless monitor transmits your heart rate to the receiver in the unit. The unit then adjusts the intensity of your workout until your heart rate is in your preset zone.

The Smooth 9.3 comes with a unique single channel heart rate control. This feature eliminates any interference with TV's, radios, vibrations, electrical currents, etc.

Having heart rate control in your treadmill ensures you get the most out of your workout. It is very accurate and convenient.
