Precor 9.23 - Heart Rate Target Zones

Owner’s Manual: Heart Rate Features 14
• The calculation used for the heart rate target zone is
(220 minus your age) multiplied by a percent and is
controlled by the user increasing or decreasing the
incline.
For example:
Fat Burn program: (220 minus your age) multiplied by
65%
Cardio program: (220 minus your age) multiplied by
80%
Refer to Table 1 in Using SmartRate.
• If you are using a chest strap on the 9.27 model, 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 heart rate grips,
grasp both touch-sensitive heart rate 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.
