What should i do if...

...OwnZone determination only seldom gives me heart rate limits which are based on heart rate variability (OZ.V)?

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 5 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 unit, such as TV sets, mobile phones, CRT monitors etc.
