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 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 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
Sometimes, dry skin or hairy chest
can create a non-conductive layer
between the electro-desand 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
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,

Important. Do not bend or stretch the
electrode

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
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.
Sources of interference or situations
that can cause Incorrect readings are:
- Your monitor picks up signals in a
radius of approximately 75 centimetres.
If you are carrying out exercises too
near to another person that is wearing
a pulsometre, your screen can pick up
their signal. To avoid maintain the
appropriate distance.
- Television set, computers, cellular
telephones, lines of high tension and
electric motors
Interference.
If you observe an erratic reading move
away from the interference source.
Your pulsometre will then return to
work correctly.
It is important to place the chest band
correctly to obtain a correct measure.
CARE AND MAINTENANCE
OF THE TRANSMITTER.-
-To maintain proper level of operation,
the transmitter has to be cleaned
regularly after use with a mild soap
and water solution. If you, however,
want to disinfect your transmitter after
