manual abstract
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 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 (O.Z.A) or the previously determined OwnZone limits based on your heart rate variability (O.Z.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 OwnZone determination 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 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 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. 5. Cardiac arrythmia may cause irregular readings. In this case consult your physician. ... 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. Precautions. ... THERE ARE NO REACTIONS TO ANY BUTTONS? Reset the Polar Heart...
