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
positioned 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 at the top of this page). If pulse readings do
not appear until you begin perspiring, re-wet the elec-
trode areas.
¥ As you walk or run on the treadmill, make sure that
you are near the center of the walking belt and within
armÕs length of the console. For the console to dis-
play pulse readings, the user must be within
armÕs 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
affected 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 above.
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.
¥ 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 counterclock-
wise, and remove the
cover.
Remove the old bat-
tery and insert a new
CR 2032 battery.
Make sure that the
battery is turned so
the writing is on
top. Replace the
battery cover and
turn it clockwise to
close it.
CHEST PULSE SENSOR CARE
¥ Dry the chest pulse sensor after each use. The
chest pulse sensor is activated when the electrode
areas are wetted and it is put on; the chest pulse
sensor shuts off when it is removed and the elec-
trode areas are dried. If the chest pulse sensor is not
dried after each use, it may remain activated longer
than necessary, draining 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 122¡F
(50¡C) or below 14¡F (-10¡C).
¥ Do not excessively bend or stretch the sensor unit
when using or storing the chest pulse sensor.
¥ Clean the sensor unit using a damp clothÑnever
use alcohol, abrasives, or chemicals.
