Nautilus T618 User Manual

Note: Do not use abrasives or chemicals such as steel wool or alcohol when you clean the chest strap, as they can
damage the electrodes permanently.
IftheConsoledoesnotdisplayaheartratevalue,thetransmittermaybeatfault.Checkthatthetexturedcontact
areas on the chest strap are making contact with your skin. You may need to lightly wet the contact areas. Check that
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.TheConsolecanread
telemetry HR signals 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.). Though your machine is Bluetooth
®
enabled, it is unable to receive input from a Bluetooth
®
enabled
strap or other device.
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.
Ifyourheartratesignaleverseemserraticaftervalidation,wipeo󰀨yourhandsandthesensorsandtryagain.
Heart Rate Calculations
Yourmaximumheartrateusuallydecreasesfrom220BeatsPerMinute(BPM)inchildhoodtoapproximately160BPMby
age60.Thisfallinheartrateisusuallylinear,decreasingbyapproximatelyoneBPMforeachyear.Thereisnoindication
thattraininginuencesthedecreaseinmaximumheartrate.Individualsofthesameagecouldhavedi󰀨erentmaximum
heartrates.Itismoreaccuratetondthisvaluebycompletingastresstestthanbyusinganagerelatedformula.
Yourat-restheartrateisinuencedbyendurancetraining.Thetypicaladulthasanatrestheartrateofapproximately72
BPM, whereas highly trained runners may have readings of 40 BPM or lower.
TheHeartRatetableisanestimateofwhatHeartRateZone(HRZ)ise󰀨ectivetoburnfatandimproveyourcardiovas-
cular system. Physical conditions vary, therefore your individual HRZ could be several beats higher or lower than what is
shown.
