10. If 5 Vdc is not present, remove the output connector from the heart rate PCA. Measure
between the pins 1 and 2 of the connector (just removed from the heart rate PCA) for 5 Vdc.
If 5 Vdc is present, replace the heart rate PCA. If the 5 Vdc is not present, measure between
the corresponding pins of J1 on the upper PCA (red and black wires). If 5 Vdc is not present
replace the upper PCA. If 5 Vdc is present, replace the upper PCA to heart rate PCA cable.
Constant or intermittent readings when neither the hand held or chest strap is in use
11. Constant or intermittent heart rate readings when neither heart rate system is in use is
caused by something in the near vicinity radiating RF energy that is being received by the
chest strap portion of the heart rate PCA.
12. Grip the hand held heart rate contacts, if the hand held signal is now being accepted,
something in the near vicinity is radiating RF energy that is being received by the chest strap
portion of the heart rate PCA.
13. The source of the radiated energy must be determined and relocated so that it no longer
affects the heart rate PCA. Televisions, cell phones, Cardio-theatre receivers, etc. are
possible sources of radiated energy.
