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

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.
