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 draw-
ing. 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 sensor should be under your clothes, tight
against your skin, and as high under the pectoral mus-
cles 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. Return the sensor 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 heart rate
monitor 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 50° Celsius (122°
Fahrenheit) or below -10° Celsius (14° Fahrenheit).
• 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 centre of the walking belt. For the
console to display heart rate 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. 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 may need to be replaced (see
page 30).

HOW TO USE THE CHEST PULSE SENSOR
PROBLEM: The walking belt slows when walked on
SOLUTION: a. If an extension cord is needed, use only a 3-conductor, 1mm 2 (14-gauge) cord that is no longer
than 1.5 m (5 ft.).
b. If the walking belt is overtightened, treadmill perfor-
mance may decrease and the walking belt may be-
come damaged. Remove the key and
UNPLUG THE
POWER CORD. Using the allen wrench, turn both rear
roller adjustment bolts counterclockwise, 1/4 of a turn.
When the walking belt is properly tightened, you should
be able to lift each side of the walking belt 8–10 cm
(3–4 in.) off the walking platform. Be careful to keep the
walking belt centred. Plug in the power cord, insert the
key, and run the treadmill for a few minutes. Repeat
until the walking belt is properly tightened.
c. If the walking belt still slows when walked on, call our Customer Service Department.
PROBLEM: The walking belt is off-centre or slips when walked on
SOLUTION: a. If the walking belt is off-centre, first remove the key and
UNPLUG THE POWER CORD. If the walking belt has
shifted to the left, use the allen wrench to turn the left
rear roller bolt clockwise 1/2 of a turn;
if the walking belt
has shifted to the right, turn the bolt counterclockwise
1/2 of a turn. Be careful not to overtighten the walking belt.
Plug in the power cord, insert the key, and run the treadmill
for a few minutes. Repeat until the walking belt is centred.
b. If the walking belt slips when walked on, first remove the
key and UNPLUG THE POWER CORD. Using the allen
wrench, turn both rear roller bolts clockwise, 1/4 of a turn.
When the walking belt is correctly tightened, you should
be able to lift each side of the walking belt 8–10 cm (3–4
in.) off the walking platform. Be careful to keep the walking
belt centred. Plug in the power cord, insert the key, and
carefully walk on the treadmill for a few minutes. Repeat
until the walking belt is properly tightened.
PROBLEM: The treadmill rocks during use
SOLUTION: a. If the treadmill rocks slightly during use, turn one or
both of the Leveling Feet (127) under the Upright (99)
until the the rocking motion is eliminated. Note: If nec-
essary, tip the treadmill forward and use a phillips
screwdriver to turn the Leveling Feet.
