• If you are using the chest strap on the 9.27, put it on
and face the display console for a few seconds. This
allows the receiver in the console to recognize the
signal from the chest strap.
• If the  icon does not blink, the treadmill cannot detect
your heart rate. Every SmartRate bar is lit. Make sure
the chest strap is positioned properly around your
chest and against your skin.
• If you prefer to use the touch-sensitive handrail grips,
grasp both touch-sensitive handrail grips and wait five
to ten seconds. Make sure both hands are moist.
Note: When a signal is detected, a number appears in
the HEART RATE display and indicates your heart rate.
• Always face forward on the treadmill and use the
handrail for balance. Keep upper body movement to a
minimum.
