Heart rate monitoring helps users monitor their levels of exertion by displaying
the heart rate during exercise.
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. 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. The
supplied chest belts use a sealed battery and are non-replaceable. Batteries in a
chest belt will last on average for 1500-2000 hours of use. Replacement belts can
be purchased from an Authorized Nautilus
®
Fitness Retailer.
HEART RATE MONITORING
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
