Precor C842i - Manual (Page 40)

User’s Reference Manual: Heart Rate Features 6
• 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 three dashes
(— — —) appear on the display, the cycle 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 hand-held heart rate feature, grasp both
touch-sensitive handlebar grips and wait five to ten seconds.
Make sure both hands are moist (not dry). When a signal is
detected, Hr flashes in the Heart Rate display. Within a few
seconds, your heart rate appears.
Important: While exercising, do not wear a chest strap and
grasp the touch-sensitive handlebar grips at the same time.
Using both features may cause erratic heart rate readings.
• Always face forward on the cycle and use the handlebars for
balance.
Using the Heart Rate
Touch-Sensitive Grips
While exercising, you must grasp both touch-sensitive handlebar
grips for a minimum of five to ten seconds to transmit your heart rate
to the display. Refer to Diagram 4.
Diagram 4: Touch-sensitive handlebar grips
Usually, the concentration of salts in a person’s perspiration
provides enough conductivity to transmit a signal to the receiver
inside the display console. However, some people, because of body
chemistry or erratic heart beats, cannot use the hand-held heart rate
feature on the cycle. A chest strap may provide better results.
