No hand held reading - No chest strap reading
11.Access the diagnostic program (Procedure 3.1). Advance to the heart rate
display portion of the diagnostic program. Verify that neither a chest strap
signal or a hand held signal is being accepted with either a heart rate test
transmitter or a chest strap transmitter.
12.Check the plug/connector connections on both the heart rate PCA (3 pin
connector), and upper PCA (J4).
13.If neither a chest strap signal or a hand held signal is being accepted, measure
between the “ground” and “5 Vdc” pins on the 3 pin connector for 5 Vdc. If 5
Vdc is present, replace the heart rate PCA.
14.If 5 Vdc is not present, remove the connector from 3 pin connector of the heart
rate PCA. Measure between the “ground” and “5 Vdc” pins 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 J4 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
15.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. Locate the
device that is causing the RF interference. Possible solutions are to relocate
the bicycle, relocate the device causing the RF interference or turn off the
device causing the RF interference while the bicycle is in use.
