Owner’s Manual: Heart Rate Features 12
Diagram 5: Heart rate target zones
• The calculation used for the heart rate target zone is:
Low range: (220 minus your age) multiplied by 55%
High range: (220 minus your age) multiplied by 85%
• After you put on the chest strap, face the display console
for a minimum of 15 seconds. This allows the receiver in
the console to recognize the signal from the chest strap.
• If you prefer to use the hand-held heart rate feature, grasp
both touch-sensitive handrail grips and wait five to ten
seconds. Your heart rate appears in the Heart Rate
display.
• If three dashes (— — —) appear on the display, the treadmill
cannot detect a heart rate. Make sure the chest strap is
positioned properly around your chest and against your
skin. If you are using the touch-sensitive handrail grips,
make sure your hands are moist (not dry) and you use
both hands.
• Always face forward on the treadmill and use the handrail
for balance. Keep upper body movement to a minimum.
