Heart Rate Monitor Troubleshooting
Handheld Heart Rate Does not Work
1. Place your hands on the handlebar
HHHR
1
(Handheld Heart Rate) handheld pulse
sensors, making full contact with both top and bottom pulse sensors for at least 15
seconds.
a. If the console displays the heart rate, no problem exists.
b. If the console does not display a heart rate, continue procedure.
2. Set the ON/OFF switch to OFF, wait 10 seconds, then toggle the ON/OFF switch to
ON. Grasp the handheld HHHR pulse sensors for a minimum of 15 seconds.
a. If the console displays the heart rate, then the cycling the power reset the
HHHR processor and the issue is fixed.
b. If the HHHR does not function correctly, continue procedure.
3. Verify that the 4-pin handlebar pulse assembly input cable connector and the Power-
/Pulse signal cable connectors are correctly plugged into the HHHR
PCA

board con-
nectors. Make sure that all pins fit properly into the connectors and that there are no
damaged or shorted pins.
a. If the cable connectors are damaged, replace the cable.
b. If the HHHR PCA connectors are damaged, replace the HHHR PCA board.
c. If the HHHR feature does not function correctly, continue procedure.
4. Verify the chassis ground cable is connected to the HHHR PCA board. Also verify the
ground cable is connected to the console weldment and provides a zero resistance
ground path to the chassis (a short, zero resistance to ground).
a. If the HHHR functions correctly, the issue is fixed.
b. If the HHHR does not function correctly, continue procedure.
5. GEN-06 treadmill only: Verify that there is a ferrite bead around the cable from the
HHHR board to the upper PCA. If missing, add the ferrite bead and verify HHHR oper-
ation. If this repair does not fix the issue, continue procedure.
6. Verify that the machine does not display a heart rate with only one hand grasping a
given left or right handlebar HHHR pulse sensor. This would indicate static damage
and require replacement of the heart rate board.
7. Remove the left (top & lower) and right (top & lower) handlebar pulse sensor assem-
blies and verify that the hand pulse sensors and electrical connections are free of cor-
rosion and have good electrical contact.
a. If the pulse sensors and/or electrical connection contacts have corrosion,
replace the corroded HHHR hand pulse assembly.
