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
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
POLAR
heart rate straps such as POLAR

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 firm, 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 influence 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.
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 influences the decrease in maximum heart rate. Individuals of the same age could have different maximum
heart rates. It is more accurate to find this value by completing a stress test than by using an age related formula.
Your at-rest heart rate is influenced 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.
