Heart Rate Analysis; Troubleshooting Heart Rate - Precor 954i Owner's Manual

Heart Rate Analysis

Every time you complete a program using the chest strap or
touch-sensitive grips, the display provides a heart rate analysis after
the workout summary. Refer to Ending a Workout.
Your average heart rate appears followed by the maximum heart
rate achieved during your workout. A third display appears, if you
entered your age, and indicates the amount of time your heart rate
remained between the target zones shown.
The heart rate analysis is based on how often your heart rate signal
is received while exercising. If you use the chest strap, the average
heart rate will be more accurate than if you occasionally grasp the
touch-sensitive grips.

Troubleshooting Heart Rate

The following table may help you understand and troubleshoot
erratic heart rate readings.
Important: A heart rate can only be detected when the Precor
heart rate receiver is properly installed in the display. A user must
wear the chest strap or grasp both touch-sensitive grips.
Table 2. Erratic heart rate readings
What Cause
appears
on the
display
Nothing The heart rate receiver is
not installed or it has
been disconnected.
HR or Hr A signal is being
detected through the
chest strap or the
touch-sensitive grips, but
a valid heart rate is not
yet established.
Note: To conduct electrical impulses from a user's heart, both
touch-sensitive grips must be grasped firmly for five to ten seconds.
Usually, the concentration of salts in a person's perspiration
provides enough conductivity to transmit a signal to the receiver in
the display console. However, because of body chemistry or erratic
heartbeats, some people cannot use the touch-sensitive grips. A
chest strap may provide better results.
What to do
Call Customer Support. Refer to
Obtaining Service.
Be sure that the chest strap is
moist, centered, and in direct
contact with your skin. If you are
using the touch-sensitive grips,
continue to grasp both of them.
Wait a few moments for your
heart rate to appear.
