PROBLEM SOLUTION
a. Make sure to stand on the foot rails and avoid moving your hands while mea-
suring your heart rate. Excessive movement may interfere with heart rate read-
ings. If the handgrip pulse sensor is not used correctly, your heart rate will not be
shown.
b. Do not hold the metal contacts too tightly; doing so may interfere with heart rate
readings.
c. For the most accurate heart rate reading, hold the contacts for about 15 seconds.
d. For optimal performance of the handgrip pulse sensor, keep the contacts clean.
The contacts can be cleaned with a soft clothÑnever use alcohol, abrasives, or
chemicals.
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.
