Your Age
• 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.
Note: When a signal is detected, a number flashes 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.
