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 thetab on one end of the chest strap into
the holein one end of the sensor unit, as shown in the
insetdrawing. Press the end of the sensor unit under
the buckleon the chest strap. The tab should be flush
withthe front of the sensor unit.
Next, wrap the chest
pulse sensor around
your chest and attach
the other end of the
chest strap to the
sensor unit. Adjust
the length of the
chest strap, if neces-
sary. The chest pulse sensor 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.
Next, 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 solution, wet both electrode areas. Return the
sensor unit to a position against your chest.
CHESTPULSE SENSOR CARE ANDMAINTENANCE
• 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 sun-
light for extended periods of time; do not expose it to
temperatures above 120° F (50° C) or below 15° 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
howthe chest pulse sensor is used withthe 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 higheron 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 readingsdo not appear untilyou
begin perspiring, rewet the electrode areas.
• As you walkor run on the treadmill, position your-
selfnear the center of the walking belt. For the con-
soleto display heart rate readings, the user must
be withinarmʼs 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 condi-
tions 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
this is a problem, try relocating the treadmill.
• The CR2032 battery may need to be replaced (see
page 24).
