Nautilus® TreadClimber®, Model TC916 Owner’s Manual
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 Fitness Retailer or at www.nautilus.com.
Contact Heart Rate
Through the use of stainless steel sensors built into the handle bar and using
sophisticated software, heart rate can be checked at any time during a workout. As with
the wireless telemetry chest belt, the heart rate is shown on the display in the same
manner.
The contact heart rate system’s ability to detect a heart rate signal is influenced by
several factors. Movement of the muscles of the upper body produces an electrical signal
(muscle artifact) that will interfere with the detection of the heart rate signal by the
sensors. Movement of the hands while they are in contact with the sensors also produces
interference. Calluses and hand lotion act as an insulating layer to reduce the signal
strength. Also, the EKG signal generated by some individuals is not strong enough to be
detected by the sensors. These individuals should opt for the telemetry method of heart
rate monitoring.
Contact heart rate input signals are acquired only during contact between your hands and
the stainless steel sensors on the handrails. To use the contact heart rate feature, place
your hands around the handles so that your hands touch both the top and the bottom of
the sensors. After the initial contact heart rate signal is detected, the controller will enter
a validation phase requiring a good heart beat signal within 10 to 15 seconds, or until
the system acquires a valid signal. During the validation phase the controller will not
recognize telemetry heart rate signals. The controller will display a heart icon. If, during
exercise, the heart rate displayed is erratic, it may be helpful to remove your hands from
the handles, wipe them and place them back on the handles. In all programs, the heart
rate is shown automatically in the display window the first time the sensors are touched.
