• if you smoke
• if you have high blood pressure
• if you have high blood cholesterol
• if you have any signs or symptoms of any disease
• if you are recovering from a serious illness or a medical treatment e.g. surgery
• if you use a pacemaker or another implanted electronic device.
Note also that in addition to exercise intensity the heart rate can be affected by, amongst others, heart, circulation
(particularly high blood pressure) and asthma and other breathing medications, as well as some energy drinks, alcohol and nicotine.
It is important to be sensitive to your body’s
reactions during the exercise. If you feel unexpected pain or tiredness regarding your exercise intensity level, it is recommended to stop the exercise or continue at a lighter intensity.
If you are allergic to any substance that comes into
contact with the skin, check the Polar heart rate monitor materials from the “Technical specifications” chapter. It is recommended that you wear the transmitter against your bare skin to ensure flawless operation. However, if you wish to wear the transmitter over a shirt, moisten the shirt well under the electrodes.
Notice to persons with pacemakers, defibrillator or
other implanted electronic device. 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.

1. Check that the elastic strap is snug enough.
2. Make sure that the electrodes of the transmitter are moistened against your skin.
3. Put on the transmitter 15-20 minutes prior to the start of your exercise to ensure good adaptation between the electrodes and your skin.
4. Start the first stage of determining your OwnZone sufficiently slowly. If you obtain the heart rate limits based on age (OZ.A) within the first 2 minutes you have raised your heart rate too quickly. The heart rate reading should not rise over 20 beats/ minute from the starting level. During the first stage you can, for example, put on your sports clothing.
5. If you reach the OwnZone limits based on age (OZ.A) or the previously determined OwnZone limits based on your heart rate variability (OZ.L) only after 10 minutes from starting specification you have not raised your heart rate sufficiently rapidly. Raise your heart rate more quickly during the OwnZone determination.
6. If you have always used walking and running to determine your OwnZone, walking uphill, cycling or using an ergometer may work better for you.
7. Stress or heavy mental loading may reduce your heart rate variability so that the needed point where the heart rate variability vanishes cannot be measured. Relax for 5 -
10 minutes before exercising by sitting down and

decreasing your heart rate.
8. For a small percentage of people the heart rate variability will not totally disappear with increasing workload. In this case the age-predicted limits are the best estimation for the exercising zone.
...THE OWNZONE LIMITS BASED ON HEART RATE
VARIABILITY (OZ.V) VARY CONSIDERABLY?
Heart rate variability reacts sensitively to all changes taking place in the body and environment. The OZ.V heart rate limits are affected by, amongst others, your daily state of fitness, the time of OwnZone determination, the type of exercise and state of mind. The lower limit of the OZ.V
heart rate limits can change for the same person by as much as 30 beats.
However it is important that the feeling of exercise carried out in the OwnZone is light or moderate. For example if you raise your heart rate too rapidly after the first stage, you may get too high OwnZone heart rate limits. If the
OwnZone limits seem to be too high we recommend that the OwnZone determination is done again.
... THERE IS NO HEART RATE READING (- -)?
1. Check that the electrodes of the transmitter are moistened and that you are wearing it as instructed.
2. Check that you have kept the transmitter clean.
3. Check that there are no sources of electromagnetic radiation in the close vicinity of the Polar wrist receiver, such as TV sets, mobile phones, CRT monitors etc.
4. Have you had a cardiac event which may have altered your EKG waveform? In this case consult your physician.
50
...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 man M91ti GBR B 50-51 within the reception range (1 metre/ 3 feet).
5. Cardiac arrythmia may cause irregular readings. In this case consult your physician.
...OTHER PERSON WITH HEART RATE MONITOR IS
CAUSING INTERFERENCE?
Your training partner may have coincidentally activated exactly the same code as you. In this case keep distance to your training partner or proceed as follows:
1. Stop the stopwatch and heart rate measurement.
2. Take the transmitter off your chest for 10 seconds.
3. Put the transmitter back and start the heart rate measurement again.
... HEART RATE READING BECOMES ERRATIC OR
EXTREMELY HIGH?
You may have come within range of strong electromagnetic signals which cause erratic readings on the wrist receiver display. Check your surroundings and move further away from the source of disturbance.
... THERE ARE NO REACTIONS TO ANY BUTTONS?
Reset the Polar heart rate monitor. Resetting clears watch settings which will return to the default settings. User information and measurement options settings will be saved.
1. Press the RESET button with a pen tip.
Display becomes full of digits.
2. Press any of the four button once.
The Polar heart rate monitor enters the Time of day display.
If you don’t press any button after reset within one minute the wrist receiver goes to the battery saving mode.
... THE DISPLAY IS BLANK OR FADING?
The Polar heart rate monitor is in battery saving mode when it leaves the factory. Wake up by pressing the OK button twice.
The Polar heart rate monitor enters the Time of day display.
