No hand held reading - Normal chest strap reading
4.Access the diagnostic program (Procedure 3.1). Advance to the heart rate
display portion of the diagnostic program. Verify that a hand held signal is
not being accepted by firmly grasping both the right and left hand held
contacts on the handlebars. Cover as much of the contact surface area with
your hands as possible (without moving your hands), you should receive a
heart rate reading within ten seconds.
5.If the hand held signal is now being accepted, something in the near vicinity is
radiating RF (radio frequency) energy that is being received by the chest
strap portion of the heart rate PCA.
6. If a hand held signal still not being accepted, skip to step 8.
7.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.
8.Access the diagnostic program (Procedure 3.1). Advance to the heart rate
display portion of the diagnostic program. Verify that a hand held signal is
not being accepted by firmly grasping both the right and left hand held
contacts with the opposite hands, right hand on the left handlebar contacts
and left hand on the right handlebar contacts. Cover as much of the contact
surface area with your hands as possible, you should receive a heart rate
reading within ten seconds. If a hand held signal is still not being accepted,
skip to step 10.
9.If a hand held signal was accepted in step 8, the hand held contact wiring is
reversed. The end of the wire harness that connects to the hand held
contacts in the handlebar is segregated into two groups. One group has blue
shrink wrap around it and the other group has black shrink wrap around it.
The “blue” group must go to the right hand contacts and the “black” group
must go to the left hand contacts. In both groups the black wire must go to
the lower contact and the red wire must go to the upper contact. If
necessary, rewire the hand held contacts as described above and test as
described in step 4.
10.If the wiring is correct, refer to Diagram 6.3 for the following measurements.
With an ohmmeter measure between the “lower right contact” pin of the 4
pin connector and the lower right hand held heart rate contact on the
handlebar. The reading should be 1 W or less. Measure between the “upper
right contact” pin of the 4 pin connector and the upper right hand held heart
rate contact on the handlebar. The reading should be 1 W or less. Measure
between the “upper left contact” pin of the 4 pin connector and the upper
left hand held heart rate contact on the handlebar. The reading should be 1 W
or less. Measure between the “lower left contact” pin of the 4 pin connector
and the lower left hand held heart rate contact on the handlebar. The reading
should be 1 W or less. If any of the above readings are greater than 1 W,
