The chest pulse sensor consists of two components:
the chest strap and the sensor unit. Follow the steps
below to put on the chest pulse sensor.
Refer to the inset drawing above. Insert the tab
on one end of the chest strap through one end of
the sensor unit as shown. Make sure to press the
end of the sensor unit under the buckle on the
chest strap.
Wrap the
sensor unit
and the
chest strap
around your
chest.
Attach the
free end of
the chest strap to the sensor unit as described
above. Adjust the length of the chest strap, if nec-
essary. The chest pulse sensor should be under
your clothing, against your skin, and as high
under the pectoral muscles or breasts as is com-
fortable. Make sure that the logo is facing forward
and is right-side-up.
Pull the
sensor unit
away from
your body a
few inches
and locate
the two
electrode
areas on the inner side. Using a saline solution
such as saliva or contact lens solution, wet both
electrode areas. Return the sensor unit to a posi-
tion against your chest.
CHEST PULSE SENSOR TROUBLE-SHOOTING
If the chest pulse sensor does not function properly,
or if the displayed pulse is excessively high or low,
try the trouble-shooting steps below.
• Make sure that the chest pulse sensor is under your
clothing, against your skin, and as high under the
pectoral muscles or breasts as is comfortable. Note:
If the chest pulse sensor does not function when po-
sitioned as described, try moving it slightly lower or
higher on your chest.
• Make sure that the logo on the sensor unit is facing
forward and is right-side-up.
• Each time you use the chest pulse sensor, use saline
solution such as saliva or contact lens solution to wet
the two electrode areas on the sensor unit (see the
drawing near the bottom of this page). If pulse read-
ings do not appear until you begin perspiring, re-wet
the electrode areas.
• As you walk or run on the treadmill, make sure that
you are near the center of the walking belt and within
arm’s length of the console. For the console to dis-
play pulse readings, the user must be within
arm’s length of the console.
• The chest pulse sensor is designed to work with
people who have normal heart rhythms. Pulse read-
ing problems may be caused by medical conditions
such as premature ventricular contractions (pvcs),
tachycardia bursts, and arrhythmia.
• The operation of the chest pulse sensor can be af-
fected by magnetic interference caused by high
power lines or other sources. If it is suspected that
magnetic interference may be causing a problem,
try relocating the treadmill.
• If the chest pulse sensor still does not function prop-
erly, test the chest pulse sensor in the following way:
Hold the chest pulse sensor and place your thumbs
over the electrode areas as shown at the left.
Next, hold the chest pulse sensor near the console.
While holding one thumb stationary, begin tapping
the other thumb against the electrode area at a rate
of about one tap per second. Check the pulse reading
on the console.
