c) If the readings still fail to appear, please have
someone else try the transmitter on and see if
that person can get it to work.
d) The following medical conditions may create
problems:
•Premature ventricular contractions, tachy-cardia
bursts, and arrythmias can result in strange or no
heart rate readings.
•If the customer has an implanted medical device
such as a pacemaker, you must consult your
physician prior to using the Polar Transmitter.

characteristics of a heart mayresult in weak ECG
signals. In many cases, where a weak ECG
signal is the reason for problems, the reliable
operation can be obtained by moving transmitter
a little bit to the left or right. Remember to rewet

Electromagnetic
transmission can be affected by high power
transmission lines or other such devices that
generate powerful magnetic fields located in the
area of equipment usage. If someone of your
associates has a Polar heart rate monitor, if
possible, borrow it for a while to check that unit
works properly in the area of exercise equipment.
If it does not and it works outside or another area
of the house, the location is very difficult for
wireless heart rate measurement and the
equipment should be moved to another location.

Question 3: Irregular heart rate reading
Answer 3:
a) The most common reason for irregular
readings especially at the beginning of exercise
session is that there is no proper connection
between skin and the electrodes of trans-

b) Elastic strap is too loose allowing ransmitter
to move during exercise.
c) Ensure that there is no anyone else wearing a

d) Pacemaker and other implanted devices may

e) Some people have a reversed ECG signal
compared to normal a ECG signal possibly
causing a transmitter to send two pulses for each
heart beat. Please turn transmitter upside-down.
f) Interferences. Electrical equipment such as
monitors, motors, LED displays, transformers
switches, cellular phones and etc. generate
electromagnetic noise which may cause missing
or extra pulses resulting in incorrect heart rate
