If you stay in close proximity to a source of electromagnetic interference for longer than one minute, the heart rate measurement may stop and time registration will be interrupted. In this case go further from the source of interference and restart the measurement. Before restarting, note the elapsed time in the display, because the time registration will restart from 0:00.

CROSSTALK

The non-coded Polar wrist receiver picks up transmitter signals within 3 feet/1 meter. 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 transmitter from your chest and use the exercise equipment as you would normally.

2.Move the wrist 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 wrist receiver in this interference free area.

4.If the Polar Heart Rate Monitor still does not work with the exercise equipment, that piece of equipment may be electrically too noisy 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.

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 transmitter are moistened and that you are wearing it as instructed.

3.Check that you have kept the transmitter clean.

Care and maintenance, page 19.

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, page 21.

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 3 feet / 1 meter 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 (3 feet / 1 meter).

Precautions/Crosstalk, page 22.

5.Cardiac arrhythmia may cause irregular readings. In this case consult your physician.
