Precor 9.33, 9.31 manual To recognize the signal from the chest strap

•The calculation used for the heart rate target zone is: (220 minus your age) multiplied by a percent.

For example:

Low range: (220 minus your age) multiplied by 55%

High range: (220 minus your age) multiplied by 85% Refer to Table 1 in Using SmartRate.

Heart Rate Target Zones

• After you put on the chest strap, face the display console

for a few seconds. This allows the receiver in the console

to recognize the signal from the chest strap.

• If Hr appears on the display, the treadmill is detecting a

signal, but has not yet determined your heart rate. Make

sure the chest strap is positioned properly around your

chest and against your skin.

• If you prefer to use the touch-sensitive grips on the 9.33,

grasp both touch-sensitive grips and wait five to ten

seconds. Make sure both hands are moist.
