HEART RATE MONITORING
CHANGING THE GAME IN HEALTH AND FITNESS

Heart rate monitoring helps you monitor your level of exertion by displaying your
heart rate during exercise. There are two methods of monitoring heart rate on
the Pro Series treadmills:
• Telemetry (e.g., Polar
®
) belt. The wireless heart rate chest belt supplied with
your treadmill transmits the heart beat signal to the receiver in the display.
The display shows the heart rate in beats per minute and uses the heart rate
value in heart rate control mode. (See Programming Instructions for more
information)
• Contact heart rate (T7.18 Model Only). Sensors on the handgrip detect heart
rate and display it on the controller.
Telemetry Heart Rate
The telemetry heart rate monitoring system consists of the receiver, located
in the display, and a transmitter belt worn across your chest. The monitoring
function is activated as soon as you strap on the chest belt and step within
range of the receiver in the machine. Two electrodes on the underside of the
chest belt sense the heart rate signal and send it to the receiver. On the T7.18,
the heart symbol on the display pulses to indicate that the display is receiving
a valid signal. On the T7.16, the far right decimal point in the Heart Rate Display
pulses to indicate that the display is receiving a valid signal. A microprocessor
in the controller calculates the heart rate and shows it, in beats per minute,
on the display.
Before you put the transmitter belt on, wet the two electrode patches (the
grooved rectangles on the reverse side of the belt). Secure the transmitter belt
as high under the pectoral muscles (chest) as is comfortable. The transmitter
belt should fi t snugly and comfortably, and allow normal breathing.
After the initial heart rate signal is detected, the display will enter a
validation phase in which four good heart beat signals lasting four seconds
are required before locking on telemetry heart rate signals for the duration
of the workout session.
If your heart rate is not being displayed, try the following:
• Move closer to the display.
• Tighten the elastic band on the chest belt.
• Adjust the belt higher or lower on your chest.
• Remoisten the electrodes.
• Test your chest strap with a machine that you know is working, or with
a heart rate watch that you know is working.
