5. SYMPTOM: THE CHEST PULSE SENSOR DOES NOT FUNCTION PROPERLY
a. If the chest pulse sensor does not function properly, refer to CHEST PULSE SENSOR TROUBLESHOOTING
on page 8.
b. If the heart rate monitor still does not function properly, the
battery should be changed. To replace the battery, locate
the battery cover on the back of the sensor unit. Insert a
coin into the slot in the cover and turn the cover counter-
clockwise to the “open” position. Remove the cover.
Next, remove the old battery from the sensor unit. Insert a
new CR 2032 battery, making sure that the writing is on
top. In addition, make sure that the rubber gasket is in
place in the sensor unit. Replace the battery cover and turn
it to the closed position.
