PROBLEM SOLUTION
a. If the chest pulse sensor does not function properly, see CHEST PULSE SENSOR
TROUBLE-SHOOTING on page 6.
b. If the chest pulse sensor still does not function prop-
erly, 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 ÒopenÓ position.
Remove the cover.
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.
