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 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
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, hear t 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 af fected
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 pr
oduce 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.
FREQUENTLY ASKED
QUESTIONS AND ANSWERS
Question 1: Heart rate readings take a long
time to appear.
Answer 1:
If the heart rate readings start appearing after you
start perspiring, this is an indication that the
transmitter electrodes weren’t initially wetted
properly prior to commencing the exercise.
Question 2: If there is no heart rate reading,
please check the following things:
Answer 2:
a) The transmitter should be placed on the rib
cage just below the breasts with the word “Polar”
facing out, reading right side up.
b) With the transmitter in position and reasonably
tight around the chest of the user, pull the
transmitter away from the body and wet the
electrodes with water, saliva, contact solution or
other saline solution.
