Troubleshooting Error Codes
If any error codes appear in the center display, turn the unit
Off and On. If the error continues to occur, call an authorized
service person for assistance. Refer to Obtaining Service.
Troubleshooting Heart Rate
Table 5 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 grips.
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 heart rate feature. A chest strap may
provide better results. Refer to the QuickStart Card for
proper placement of the chest strap.
