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 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 OwnZone-heart rate limits seem to be too
high we recommend that the OwnZone determination is
done again.
... 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:
