8.For a small percentage of people the heart rate variability will not totally disappear with increasing workload. In this case the
...THE OWNZONE HEART RATE LIMITS BASED ON HEART RATE VARIABILITY (O.Z.V) VARY CONSIDERABLY?
Heart rate variability reacts sensitively to all changes taking place in the body and environment. The O.Z.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 O.Z.V heart rate limits can change for the same person by as much as 30 beats.
However it is important that the effect of exercise carried out in the OwnZone feels 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
... SOME OTHER PERSON USES MY POLAR M71 ti
HEART RATE MONITOR?
Polar M71 ti determines the OwnZone heart rate limits on the basis of heart rate and age. If someone else uses your Polar M71 ti Heart Rate Monitor it is necessary to zero the O.Z.V. heart rate limits which are in the memory. Zeroing is done by resetting the age in the USER mode with the 
/LIGHT button.
Even although the user is the same age as you the age must still be reset in order that the O.Z.V heart rate limits are zeroed. If this is not done the Polar M71 ti may give the following user OwnZone heart rate limits based on your heart rate variability which is stored in the memory of the equipment.
Polar M71 ti calculates the OwnCal energy expenditure based on the gender, weight, exercise time and heart rate. Therefore the weight and gender must be reset.

Changing the user also affects the calculation of the total calorie expenditure (T.KCAL). If the T.KCAL reading is not zeroed when the user changes, the Polar M71 ti adds the calorie expenditure of new exercise periods into its memory, even although the user information is changed. If you want that only your own energy expenditure is stored in the Polar M71 ti’s memory you must set the calorie calculator off in the USER mode when the equipment is used by someone else.
... 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. Care and maintenance.
3.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.
4.Have you had a cardiac event which may have altered your EKG 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 arrhythmia 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:
