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
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
®
compatible 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.
NOTICE: To prevent interference with the telemetry HR receiver, do not
place any personal electronic devices in the left side of the media
tray.*
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 off your hands and the sensors and try again.

The Heart Rate table is an estimate of what Heart Rate Zone (HRZ) is effective 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.

  • when I am pedalling the digital display doesn't recognize that I am pedalling and tells me to start pedalling...then after five seconds the unit goes into Pause mode, the display also doesn't show that I have gone any distance in that no mileage is registered... Submitted on 19-1-2022 at 19:25
