Product Owner’s Manual: Maintenance 16
Long-Term Storage
When the EFX is not in use for any length of time, ensure that the
optional power adapter is unplugged from its power source and is
positioned so that it and the power cord will not become damaged
or interfere with people or other equipment.
Troubleshooting Error Codes
If any error codes appear in the display, call an authorized service
person for assistance. Refer to Obtaining Service.
Troubleshooting Heart Rate
Table 3 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 user
maintains a minimum 40 spm. A user must also wear the chest
strap or grasp both touch-sensitive handrail grips.
Table 3. Erratic heart rate readings
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 touch-sensitive
heart rate feature. A chest strap may provide better results.

Face the display and keep your upper
body movement to a minimum. Wear a
chest strap or grasp both touch-
sensitive handrail grips. Allow at least 15
seconds for your heart rate signal to be
transmitted to the display. If the dashes
continue to appear, check the cable
connections.

requires more
time to
establish a

Be sure the chest strap is moist,
centered, and in direct contact with your
skin. If using the touch-sensitive handrail
grips, continue holding the grips with
both hands and make sure your hands
are moist, not dry.
