the curve of the transmitter is oriented upward. If no signal appears or you need further assistance, call your Nautilus
Representative.
Before discarding a chest strap, remove the battery. Dispose of in accordance with local regulations and/or
at approved recycling centers.
Remote Heart Rate Monitor
MonitoringyourHeartRateisoneofthebestprocedurestocontroltheintensityofyourexercise.ContactHeartRate
(CHR)sensorsareinstalledtosendyourheartratesignalstotheConsole.TheConsolecanalsoreadtelemetryHRsig-
nalsfromaHeartRateChestStrapTransmitterthatoperatesinthe4.5kHz-5.5kHzrange.
Note: The heart rate chest strap must be an uncoded heart rate strap from Polar Electro or an uncoded POLAR
®
com-
patible model. (Coded POLAR
®
heart rate straps such as POLAR

OwnCode

chest straps will not work with this
equipment.)
If you have a pacemaker or other implanted electronic device, consult your doctor before using a wireless
chest strap or other telemetric heart rate monitor.
Contact Heart Rate Sensors
ContactHeartRate(CHR)sensorssendyourheartratesignalstotheConsole.TheCHRsensorsarethestainlesssteel
parts of the Handlebars. To use, put your hands comfortably around the sensors. Be sure that your hands touch both the
topandthebottomofthesensors.Holdrm,butnottootightorloose.Bothhandsmustmakecontactwiththesensorsfor
the Console to detect a pulse. After the Console detects four stable pulse signals, your initial pulse rate will be shown.
Once the Console has your initial heart rate, do not move or shift your hands for 10 to 15 seconds. The Console will now
validatetheheartrate.Manyfactorsinuencetheabilityofthesensorstodetectyourheartratesignal:
• Movementoftheupperbodymuscles(includingarms)producesanelectricalsignal(muscleartifact)thatcaninterfere
with pulse detection. Slight hand movement while in contact with the sensors can also produce interference.
• Calluses and hand lotion may act as an insulating layer to reduce the signal strength.
• SomeElectrocardiogram(EKG)signalsgeneratedbyindividualsarenotstrongenoughtobedetectedbythesensors.
• Theproximityofotherelectronicmachinescangenerateinterference.
