HOW TO PUT ON THE CHEST PULSE SENSOR
The chest pulse sensor consists of two components—
the chest strap and the sensor unit (see the drawing
below). Insert the tab on one end of the chest strap
into one end of the sensor unit, as shown in the inset
drawing. Press the end of the sensor unit under the
buckle on the chest strap. The tab should be flush with
the front of the sensor unit.
Next, wrap the
chest pulse sen-
sor around your
chest and attach
the other end of
the chest strap to
the sensor unit.
Adjust the length
of the chest strap,
if necessary. The
chest pulse sen-
sor should be under your clothes, tight against your
skin, and as high under the pectoral muscles or
breasts as is comfortable. Make sure that the logo on
the sensor unit 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
(the electrode areas are covered by shallow ridges).
Using saline solution such as saliva or contact lens so-
lution, wet both electrode areas. Then, return the sen-
sor unit to a position against your chest.
CHEST PULSE SENSOR CARE AND MAINTENANCE
• 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 nec-
essary, 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
it 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 cloth—never
use alcohol, abrasives, or chemicals. The chest
strap may be hand washed and air dried.
CHEST PULSE SENSOR TROUBLESHOOTING
The instructions on the following pages explain
how the chest pulse sensor is used with the con-
sole. If the chest pulse sensor does not function
properly, try the steps below.
• Make sure that you are wearing the chest pulse sen-
sor as described at the left. Note: If the chest pulse
sensor does not function when positioned as de-
scribed, move it slightly lower or higher on your
chest.
• Use saline solution such as saliva or contact lens
solution to wet the two electrode areas on the
sensor unit. If heart rate readings do not appear until
you begin perspiring, re-wet the electrode areas.
• As you walk or run on the treadmill, position your-
self near the center of the walking belt.
For the
console to display heart rate readings, the user
must be within armʼs length of the console.
• The chest pulse sensor is designed to work with
people who have normal heart rhythms. Heart rate
reading problems may be caused by medical
conditions such as premature ventricular contrac-
tions (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
this is a problem, try relocating the treadmill.
• The CR2032 battery in the chest pulse sensor may
need to be replaced (see page 24).
