Frequently
Asked
Questions
WHAT SHOULD I DO IF...
...THERE IS NO HEART RATE READING?
1. Check that the elastic strap is snug enough.
2. Check that the electrodes of the Polar Transmitter are
moistened and that you are wearing it as instructed.
3. Check that you have kept the Polar Transmitter clean.
Care and maintenance.
4. Check that there are no sources of electromagnetic
radiation in the close vicinity of the Polar Wrist Receiver,
such as TV sets, cellular phones, CRT monitors etc.
Precautions.
5. Have you had a cardiac event which may have altered
your ECG waveform? In this case consult your physician.
...HEART SYMBOL FLASHES IRREGULARLY?
1. Check that your Polar Wrist Receiver is inside the
transmission range and not further that 1 metre/ 3 feet from
the Polar Transmitter you are wearing.
2. Check that the elastic strap has not become loose during
exercise.
3. Make sure that the electrodes of the Transmitter are
moistened.
4. Make sure that there is no other heart rate transmitter within
the reception range (1 metre/ 3 feet). Precautions/
Crosstalk.
5. Cardiac arrythmia may cause irregular readings. In this
case consult your physician.
POLAR HEART RATE MONITOR AND INTERFERENCE
ELECTROMAGNETIC INTERFERENCE
Disturbances may occur near high voltage power lines,
televisions, cars, bike computers, some exercise equipment or
cellular phones.
CROSSTALK
The non-coded Polar Wrist Receiver picks up transmitter
signals within 1 metre/ 3 feet. Therefore, when you are using
your Polar Heart Rate Monitor make sure no other transmitter
is within that range. Signals from more than one transmitter
picked up simultaneously can cause an incorrect readout.
EXERCISE EQUIPMENT
Several pieces of exercise equipment with electronic or electrical
components such as LED displays, motors and electrical
brakes may cause interfering stray signals. To try to tackle
these problems, relocate the Polar Wrist Receiver as follows:
1. Remove the Polar Transmitter from your chest and use the
exercise equipment as you would normally.
2. Move the Receiver around until you find an area in which it
displays no stray reading or flashing of the heart symbol.
Interference is often worst right in front of the display panel
of the equipment, while the left or right side of the display is
relatively free of disturbance.
3. Put the Transmitter back on the chest and keep
the Receiver in this interference free area.
4. If the Polar Heart Rate Monitor still does not work with the
exercise equipment, this piece of equipment may be too
noisy electrically for wireless heart rate measurement.
Notice for persons with pacemakers
Persons who have a pacemaker use the Polar Heart Rate
Monitor at their own risk. Before starting use, we always
recommend an exercise test under doctor’s supervision. The
test is to ensure the safety and reliability of the simultaneous
use of the pacemaker and the heart rate monitor.
