PROBLEM: The chest pulse sensor does not function properly
SOLUTION: a. If the chest pulse sensor does not function properly, see CHEST PULSE SENSOR
TROUBLESHOOTING on page 10.
b. If the chest pulse sensor 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 counterclockwise 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.
