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.
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
can
produce
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
use, a chlorine solution similar to that
approved for pool swimming may be
used.
Please
avoid
untested
disinfecting compounds, they may
cause permanent damages to the
transmitter.
After
disinfecting,
transmitter should be cleaned by
water or soap solution to avoid allergic
reactions on skin.
- After using, clean and dry your unit
carefully. A weak signal can be due to
dirt.
- Do not expose your band to
excessive heat or cold.
- Do not leave your unit exposed to
direct sunlight or in your car
- Keep your unit in a well ventilated
place.
Note. Never use abrasives and other
chemicals as they may cause
permanent damages to the electrodes
decreasing conductivity or durability.
Storing of transmitter. It is highly
recommended to store transmitter in
cool and dry place to maximise the
battery life. Before storage all moisture
should be wiped off.
