The chest band (optional extra) transmits the pulse
rate by contact with the chest and sends signal to
the display clock.
PRECAUTION. Before beginning any exercise
program, you should consult to 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
putting the transmitter on
correctly as described
below.
1. Attach the chest
transmitter to the elastic
belt.
2. Adjust the strap to fit
tightly and comfortable.
3. Secure the strap around your chest, below the
breasts and lock the buckle.
4. Without detaching the elastic strap, 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 recommend 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 centre and
the electrode contacts flat against the skin. Doing

HOW TO IMPROVE CONDUCTIVITY
The technology used for the chest transmitters is
based on measuring ECG signals operation, it is
important for successful heart rate measurement
that a proper electrical connection between the skin
and the electrodes of Polar Transmitter can be
established and maintained during exercise.
Sometimes, dry skin or hairy chest can create a non-
conductive layer between the electrodes and chest
which prevents proper and reliable operation of
transmitter. Conductivity can be easily improved
through properly wetting properly 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.
ECG signal of some human beings can be so weak
or the optimum location may vary that
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 signal
can result from heart diseases, heart surgeries or
natural characteristic of 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 pulsometre, just as all
devices that do not use cables, can it be affected
by electromagnetic interference. These can cause
incorrect readings on your pulsometre.

Incorrect readings are:
