INSTRUCTIONS FOR THE
TELEMETRIC PULSE SENSOR
16
USE OF THE CHEST BAND
(Pulse sensor)
The chest band transmits the pulse rate
by contact with the chest and sends a
signal to the display.
PRECAUTION: Before beginning any
exercise program, you should consult
your doctor and tell him about the
intensity of the exercise. If you use a
pacemaker do not use the band until you
have consulted with your doctor.
ASSEMBLY AND USE OF THE CHEST
BAND
The key to flawless heart rate
measurement is putting the transmitter
on correctly as described below.
1. Attach the chest transmitter (E) to the
elastic belt (F).
2. Adjust the strap (F) to fit tightly and
comfortable.
3. Secure the strap (F) around your
chest, below the breasts and lock the
buckle.
4. Without detaching the elastic strip (F),
pull the transmitter away from your body
exposing the two grooved areas that are
located on the inside of the transmitter.
Wet the grooved electrode areas with
saliva, contact lens solution or any other
saline solution. Return to its original
position against your skin with the Polar
text in a central up-right position.
5. After wetting the electrodes, do not
slide the transmitter around on your body
as this has the effect of drying the
electrodes. It is recommended to wear
the transmitter against bare skin to
ensure successful operation. If a
transmitter is worn over a shirt, the shirt
has to be well wetted under the electrode
area to ensure proper conductivity.
Wear the band as high as possible just
below the breast bone with the
transmitter in the center and the
electrode contacts flat against the skin.
Doing this correctly assures a correct
reading of the heart beat.
HOW TO IMPROVE CONDUCTIVITY
The technology used for the chest
transmitters is based on measuring ECG
signals. It is important for successful
heart rate measurement that a proper
electrical connection between the skin
and the electrodes of the Polar
Transmitter can be established and
maintained during exercise. Sometimes,
dry skin or hairy chest can create a
nonconductive layer between the
electrodes and chest which prevents
proper and reliable operation of the
transmitter.
Conductivity can be easily improved
through properly wetting the electrodes
by water, saliva, contact lens solution or
other saline solution.
HOW TO GET A PROPER ECG
SIGNAL FOR TRANSMITTER
It is possible, however, that despite the
above mentioned recommendation, the
transmitter does not work well due to a
slightly divergent ECG signal. The ECG
signal of some people can be so weak or
the optimum location may vary so that
the transmitter has to be moved slightly
to left or right in order to get sufficient
voltage difference for the proper
operation of transmitter. Weak ECG
signals can result from heart diseases,
heart surgeries or the natural
characteristics of the heart and the
location of the body potential vectors.
Important. Do not bend or stretch the
electrode strips as this may permanently
damage sensitive internal electronic
components. Recommendation. If you
have a sunken chest, the rubber
electrodes may not make a good contact
without additional pressure and the result
will be intermittent readings. Adding a
second chest band on the transmitter
can solve this problem.
Please remember that this chest band,
just as all devices that do not use cables,
