Maintaining The Transmitter Belt; Contact Heart Rate; Heart Rate Priority - Nautilus U916 Owner's Manual

HEART RATE PRIORITY

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.
HEART RATE PRIORITY
Both contact heart rate and telemetry (e.g., Polar®) heart rate signal detection are available. The default
priority of heart rate input is "EITHER INPUT."
