START THE HEART RATE

MEASUREMENT

1. Wear the Polar transmitter and the wrist receiver as described in the chapter Getting going.

2. To make sure that the code search will be successful:

• Keep the wrist receiver within 1 metre / 3 feet of your transmitter

• Check that you are not near to other people with heart rate monitors, high voltage power lines, televisions, mobile phones, cars, exercise equipment etc.

3. Begin with display showing Time of day.

4. Press MODE to enter the MEASURE mode.

A heart shaped frame appears. The wrist receiver starts searching for coded transmission for max. 15 seconds.

Heart rate measurement commences and the heart symbol inside the frame starts flashing.

Your heart rate reading (in beats per minute) appears in the display.

If the code search was not successful, the frame around the heart symbol will disappear after 15 seconds. Go back to step 2 to repeat the code search.

If you still do not succeed in code searching, but your heart rate is displayed and the heart symbol without a frame is flashing, you can start exercising but your wrist receiver may become disturbed by other heart rate monitors.


5. Start the stopwatch by pressing SET/START/STOP.

Stopwatch starts running and you hear a long beep.

Automatic recording begins.

Determining your OwnZone begins if you have set the option ON.

6. You can now start your warmup with your Polar M71 ti.

DETERMINE YOUR OWNZONE

Polar M71 ti is able to determine the individual training heart rate zone for you. This exercise zone is called your

OwnZone (O.Z.).

For most adults, OwnZone corresponds to 65-85 % of the maximum heart rate. OwnZone is suitable for cardiovascular training either for health-related or fitness improvement purposes.

OwnZone works well for those whose goal is weight control via physical activity and exercise, because the

OwnZone intensity corresponds to intensity from “light to moderate” to “moderate”. Exercise of this intensity level can be conducted even for extended periods safely and often and yields the best results for weight loss.

The OwnZone can be found during a warmup period of an exercise session lasting 2-10 minutes.

16.1.2001, 11:01

H O W T O D E T E R M I N E

Y O U R O W N Z O N E

OwnZone is easiest determined by walking and jogging as instructed below. However, you are able to find your

OwnZone with other exercise modes as well, e.g. exercising with a stationary bike. The principle is that you start exercising very slowly with light intensity and gradually increase your heart rate.

1. Check that you have set your personal user information correctly.

2. Because the heart rate variability measurement needs every heart beat to be picked up properly, make sure that the transmitter belt is tight enough and the electrodes well moistened.

3. Check that you have the OwnZone function ON.

4. Start the heart rate measurement as described earlier.

5. Start the stopwatch.

appears in the display.

Stopwatch starts running.

6. There are five stages in finding your OwnZone. After each stage you hear a long beep which tells you that you should increase your speed slightly. The display shows which stage you are in:

1. Walking at very slow pace for 2 min.

2. Walking at brisk pace for 2 min.

3. Walking at very brisk pace for 2 min.

4. Jogging at slow pace for 2 min.

5. Running for 2 min.

24

7. At some point during the stages 2 - 5 you hear two beeps. This indicates that Polar M71 ti has determined m71ti manual GBR/B 24-25 your exercising limits and you can continue your exercising.

The determined heart rate limits are displayed for a few seconds.

You can recall the limits onto the display by bringing the watch close to the transmitter.

If needed you can reset the stopwatch to zero and restart OwnZone determination:

1. Stop the OwnZone determination by pressing SET/START/

STOP.

Heart rate limits for your previously determined

OwnZone appear on the display.

2. Stop the stopwatch by pressing SET/START/STOP.

3. To reset the stopwatch press and hold SET/START/STOP for 2 seconds.

4. To restart the stopwatch press SET/START/STOP.

You can turn the OwnZone timing signals off by pressing and holding /LIGHT for two seconds before starting the OwnZone determination.

However you will hear two long beep signals at the time Polar M71 ti has determined your OwnZone heart rate limits.

16.1.2001, 11:01

25

O W N Z O N E M E T H O D S

Polar M71 ti uses multiple methods for determining your safe OwnZone. The primary method is to measure and analyse the heart rate variability and thereby determine the most individual and current parameters.

If your heart rate exceeds the safety limit during the determination, Polar M71 ti picks up your latest OwnZone definition based on heart rate variability. Alternatively, if there is no previous determination in memory, Polar M71 ti will automatically calculate Target Zone limits which are based on your age predicted maximum heart rate. These methods ensure the safest possible exercising zone determination for you.

The method used in defining the exercising Target Zone is indicated after the two beeps as follows:

1. O.Z.V (OwnZone Variability) and the currently determined OwnZone limits appear on the illuminated display.

2. O.Z.L (OwnZone Latest) and your previously determined OwnZone limits appear on the illuminated display.

3. O.Z.A (OwnZone Age) and your age-predicted heart rate limits appear on the illuminated display.

H O W T O U S E P R E V I O U S L Y

D E T E R M I N E D O W N Z O N E

Every time you start the stopwatch and have the OwnZone option on, Polar M71 ti starts finding your OwnZone. You can determine your OwnZone for every exercise session separately. At least it should always be performed when changing exercise environment, exercise mode or if you have abnormal feelings about your physiological state when starting the exercise.

However, you can choose to exercise with the latest

OwnZone limits in case you are not willing to start the process of redefining your OwnZone.

1. Start the heart rate measurement and stopwatch as usual.

appears on the display.

2. Press SET/START/STOP. Polar M71 ti starts using your latest determined OwnZone.

O.Z.L and the values for your previously determined

OwnZone appear momentarily on the illuminated display.

In case there is no previously determined OwnZone in memory, Polar M71 ti starts using your age predicted exercising limits.

O.Z.A and your age-predicted heart rate limits appear on the illuminated display.

POLAR TRANSMITTER

The estimated average battery life of the Polar transmitter is 2500 hours of use. Contact your distributor/ dealer for a transmitter replacement. Customer Care Charter for detailed instructions.

Polar recycles used transmitters.

POLAR M71 ti RECEIVER

The estimated average battery life of the Polar M71 ti receiver is 1 year in normal use (2h/day, 7 days a week).

However, because the battery is inserted at the factory, the actual life of your first battery once in your possession may be less than the estimated battery life. Note also that excessive use of the backlight and the alarm signals will use the battery more rapidly.

Do not open the Polar wrist receiver yourself. To ensure the water resistance properties and the use of qualified components, the wrist receiver battery should be replaced only by a person authorised by Polar Electro Oy. At the same time a full periodic check of the Polar Heart Rate

Monitor will be done. Customer Care Charter for detailed instructions.

S E R V I C E

Should your Polar Heart Rate Monitor need service, see

Customer Care Charter to contact an authorised Polar

Service Center.

Water resistance cannot be guaranteed after unauthorised service.


PRECAUTIONS

U S I N G A P O L A R H E A R T R A T E

M O N I T O R I N A W A T E R

E N V I R O N M E N T

Polar M71 ti Heart Rate Monitor is water resistant to 50 metres/160 feet. To maintain the water resistance, do not operate the buttons of the wrist receiver under water.

Heart rate measurement in a water environment is technically demanding for the following reasons:

• Pool water with a high chlorine content and seawater may be very conductive and the electrodes of Polar transmitter may get short circuited and ECG signals cannot be detected by the transmitter unit.

• Jumping into the water or strenuous muscle movement during competitive swimming may cause water resistance that shifts the transmitter on the body to a location where it is not possible to pick up ECG signal.

• The ECG signal strength varies depending on the individual’s tissue composition and the percentage of people who have problems in heart rate measuring is considerably higher in a water environment than in other use.

ELECTROMAGNETIC INTERFERENCE

Disturbances may occur near high voltage power lines, traffic lights, overhead lines of electric railways, electric bus lines or trams, televisions, car motors, bike computers, some

35

16.1.2001, 11:01

motor driven exercise equipment, cellular phones or when you walk through electric security gates.

CROSSTALK

The non-coded Polar wrist receiver picks up transmitter signals within 1 metre/3 feet. Therefore, make sure no other transmitter is within that range. Signals from more than one transmitter picked up simultaneously can cause an incorrect readout.

EXERCISE EQUIPMENT

Several pieces of exercise equipment with electronic or electrical components such as LED displays, motors and electrical brakes may cause interfering stray signals. To try to tackle these problems, relocate the Polar wrist receiver as follows:

1. Remove the transmitter from your chest and use the exercise equipment as you would normally.

2. Move the receiver around until you find an area in which it displays no stray reading or flashing of the heart symbol. Interference is often worst right in front of the display panel of the equipment, while the left or right side of the display is relatively free of disturbance.

3. Put the transmitter back on the chest and keep the wrist receiver in this interference-free area as far as it is possible.

4. If the Polar Heart Rate Monitor still does not work with the exercise equipment, this piece of equipment may be electrically too noisy for wireless heart rate measurement.

Notice for 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.


FREQUENTLY ASKED

QUESTIONS

W H A T S H O U L D I D O I F . . .

... OWNZONE DETERMINATION ONLY SELDOM GIVES

ME HEART RATE LIMITS WHICH ARE BASED ON HEART

RATE VARIABILITY (O.Z.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 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.

37

16.1.2001, 11:01

38

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:

39

16.1.2001, 11:01

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.

Precautions.

... THERE ARE NO REACTIONS TO ANY BUTTONS?

Reset the Polar Heart Rate Monitor. Resetting clears all memory values and settings will return to the default settings.

1. Simultaneously press all three buttons.

Display becomes full of digits.

2. Press SET/START/STOP button once.

The Polar M71 ti enters the Time of day mode.

... THE DISPLAY IS BLANK OR FADING?

Usually the first sign of a discharged battery is fading of the digits when using the backlight. Have the batteries checked. Customer Care Charter

... THE BATTERY OF THE WRIST RECEIVER MUST BE

REPLACED?

We recommend having all service done by an authorised

Polar Service. This is especially necessary to ensure the warranty remains valid and is not affected by incorrect repair procedures done by an unauthorised agent. Polar

Service will test your wrist receiver for water resistance after battery replacement and make a full periodic check of the complete Polar Heart Rate Monitor. Care and

maintenance/Batteries and Customer Care Charter.
