Troubleshooting Heart Rate - Precor M9.33i Owner's Manual

Troubleshooting Heart Rate

Table 6 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
and the treadmill is turned on. You must also wear the chest
strap or hold on to both touch-sensitive handrail grips.

Be sure the chest strap
is in direct contact with
your skin. If using the
grips, use both hands and
make sure your hands are
moist, not dry.
If the LED is pulsating,
it indicates that the
heart rate equipment is
working properly.
Note: To conduct electrical impulses from a user's heart,
both touch-sensitive handrail 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 heart rate feature. A chest strap
may provide better results. Refer to the QuickStart Card for
proper placement of the chest strap.
