Heart rate monitoring helps users monitor their levels of exertion by displaying
the heart rate during exercise. The are two methods of monitoring heart rate on
the Commercial Series T9.14 treadmill:
Telemetry Heart Rate
The telemetry heart rate monitoring system consists of the receiver, located
in the display, and a transmitter belt (purchased separately) 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.
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 fit 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.
Maintaining the Transmitter Belt
Clean the chest belt regularly with mild soap and water, then dry thoroughly –
residual sweat and moisture keeps the transmitter active and will drain the
battery in the transmitter. Do not use abrasives or chemicals such as steel
wool or alcohol for cleaning, as they can damage the electrodes permanently.
Replacement belts can be purchased from an Authorized Nautilus

WARNING!
Pacemaker users
should not use the
telemetry transmitter
without first consulting
with their doctor.
Telemetry (e.g. using a Polar®
or Polar-compatible transmitter
belt). A Polar-compatible heart
rate chest belt 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.
Contact heart rate (handgrip).
Sensors on the handgrip detect
heart rate and display it on
the controller.
