HEART RATE MONITORING

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.

Contact Heart Rate (T7.18 model only)

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 manor.

The contact heart rate system’s ability to detect a heart rate signal is inﬂ uenced by

several factors. Movement of the muscles of the upper body produces an electrical

signal 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. For this reason users

should avoid moving their hands while using the

contact heart rate grips. For reasons of safety it is

also recommended that users not use the contact

heart rate feature while running and instead use

the telemetry chest belt method. 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 display will not recognize telemetry heart rate signals. 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.
