• If the chest pulse sensor does not function properly
after you have followed all of the above instructions,
the battery should be replaced in the following way:
Locate the battery
cover on the back of
the sensor unit.
Insert a coin into the
slot in the cover,
turn the cover coun-
terclockwise, and
remove the cover.
Remove the old
battery and insert a
new CR 2032 bat-
tery. Make sure
that the battery is
turned so the writ-
ing is on top.
Replace the battery
cover and turn it
clockwise to close

CHEST PULSE SENSOR CARE
• Thoroughly dry the chest pulse sensor after each
use. The chest pulse sensor is activated when the
electrode areas are wetted and the chest pulse sen-
sor is put on; the chest pulse sensor shuts off when
it is removed and the electrode areas are dried. If
the chest pulse sensor is not dried after each use, it
may remain activated longer than necessary, drain-
ing the battery prematurely.
• Store the chest pulse sensor in a warm, dry place.
Do not store the chest pulse sensor in a plastic bag
or other container that may trap moisture.
• Do not expose the chest pulse sensor to direct
sunlight for extended periods of time. Do not expose
the chest pulse sensor to temperatures above 50° C
(122° F) or below -10° C (14° F).
• Do not excessively bend or stretch the sensor unit
when using or storing the chest pulse sensor.
• Clean the sensor unit using a damp cloth—never
use alcohol, abrasives, or chemicals. The chest
strap may be hand washed and air dried.
