GETTING GOING

H E A RT R AT E M O N I T O R PA RT S
The elastic strap holds the transmitter comfortably, yet
firmly, in the correct position.
The Polar transmitter
detects your heart rate and
transmits it to the wrist
receiver.
The Polar M91 ti™ wrist
receiver displays your heart
rate and other data during
exercise. Enter your
personal settings
into the receiver
and analyze the
exercise file after
you’re done.

• Briefly pressing a button (approximately 1 second)
will do different things than pressing and holding
the button for a longer period of time
(approximately 2 to 5 seconds).
• The buttons are slightly stiffer than those of an
ordinary watch to prevent them from being
pressed accidentally.
• You can always return to the Time of Day display
from the Options setting or File recalling loops by
pressing and holding the OK button.
• See the glossary for display symbols and text
interpretation.

E A S Y S TA R T
HOW TO PREPARE THE WRIST RECEIVER
1. Since the display is blank when the receiver leaves the
factory, you have to activate the wrist receiver by
pressing the OK button twice, after which the Time of
Day display appears. This is a one-off procedure; once
you have turned on your receiver you can not turn it off
anymore.
2. You may start measuring your heart rate right away
using the default settings. However, the following
settings are ones that it would be useful to change as
soon as possible: Time of day (see section Setting the
watch) and personal user settings (see section User
information settings).
3. Wear the wrist receiver as you would wear an ordinary
watch. If you need to shorten the wrist band we
recommend you visit a local watch shop. However, if you
wish to do it yourself keep the band sections the same so
that the buckle will stay in the middle. Detach the buckle
from the OK button side band by pressing the spring, cut
the band, attach the buckle. If needed, detach the buckle
from the logo side band and cut the same length as you
cut from the other band, attach the buckle.

10/12/01, 13:22

HOW TO PUT THE TRANSMITTER ON

1. Attach the transmitter to the
elastic strap.

2. Adjust the strap length to fit
snugly and comfortably. Secure
the strap around your chest,
below the chest muscles.

3. Lift the transmitter off your
chest and moisten the grooved
electrode areas on the back.

4. Check that the wet electrode
areas are firmly against your
skin and the Polar logo is in a
central, upright position.

HOW TO START MEASURING YOUR HEART RATE
1. Begin with the display that shows the time of day.
2. Keep the wrist receiver within 3 feet/ 1 meter of your
transmitter.
3. Check that you are not near other people that have
heart rate monitors, high voltage power lines, televisions,
mobile phones or other sources of electromagnetic
disturbance.
4. Press the OK button to start measuring your heart rate. A
heart symbol will start flashing and your heart rate (beats
per minute) will appear in a maximum of 15 seconds.
5. Press OK again. The stopwatch starts running and you
can start exercising. The exercise data will only be stored
in a file if you have turned the stopwatch on.

man M91ti USA GBR A 2001

10/12/01, 13:22

HOW TO STOP MEASURING YOUR HEART RATE
1. Press the OK button. The stopwatch stops.
QUIT? Appears in the display. Heart rate measurement
without exercising limits or calorie calculation continues.
2. Press
Scroll Up. The heart rate measuring stops.
The receiver shows the Time of Day display again.

AFTER EXERCISING
1. Carefully wash the transmitter with a mild soap and
water solution.
2. Rinse it with pure water.
3. Dry the transmitter carefully with a soft towel.
4. Store the transmitter in a clean and dry place. Dirt
impairs the elasticity and functioning of the transmitter.
Sweat and moisture can keep the electrodes wet and the
transmitter activated, which shortens battery life.

The OwnCal calorie calculation starts when your heart rate
reaches 100 bpm. The higher the heart rate, the faster the
energy expenditure accumulation. Energy expenditure
depends on body weight; the heavier the weight the
higher the energy expenditure. Men’s calorie expenditure is
more intense than women’s at the same heart rate.
The energy expenditure measurement with Polar heart rate
monitor is most accurate in continuous activities such as
walking, cycling and jogging. Polar heart rate monitor
shows the energy expenditure in kilocalories (kcal).
When you expend calories, your body actually uses fat and
carbohydrates as energy resources. The amount of fat from
the total calorie expenditure varies between 10% - 60%.
The rest (40% - 90%) is mostly carbohydrates.
The lower the heart rate, the bigger the fat percentage is
of the total energy expenditure. If you want to control
weight by exercising, it is recommended to aim at as big a
fat percentage of total energy expenditure as possible.
Exercise with OwnZone Low.

OWNZONE
Polar heart rate monitor is able to determine the individual
training heart rate zone for you. This exercise zone is called
your OwnZone (OZ).
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 corresponds to intensity from “light to
moderate” to “moderate”. Exercise of this intensity level
can be conducted even for extended periods safely and
often yields the best results for weight loss.
The OwnZone can be found during a warmup period of an
exercise session lasting 1-10 minutes.

HOW TO DETERMINE YOUR OWNZONE
OwnZone is easily 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 OwnZone determination 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 set the OwnZone function on.

4. Start the heart rate measurement as described earlier.
5. Start the stopwatch.
OZ
appears in the display.
Stopwatch starts running.
6. There are five stages in finding your OwnZone. OwnZone
appears typically on the 3 rd or 4 th stage (in 5-6 minutes).
Keep your heart rate below 100 bpm during the first
stage. After each stage you should increase your heart rate
10-20 bpm. The display shows which stage you are in:
Walking at very slow pace for 2 min.
Walking at brisk pace for 2 min.
Walking at very brisk pace for 2 min.
Jogging at slow pace for 2 min.
Running for 2 min.
7. At some point during the stages 1 - 5 you hear two
beeps. This indicates that Polar heart rate monitor has
determined your exercising limits and you can continue
your exercising.
The determined heart rate limits are
displayed for a few seconds.
EXERCISE appears in the display.
You can recall the limits onto
the display by bringing the
receiver close to the

OWNZONE METHODS
Polar heart rate monitor uses multiple methods for
determining your OwnZone. The primary method is based
on measuring and analysing the heart rate variability
during graded exercise (OZ.V).
If your heart rate exceeds the safety limit during the
determination, Polar heart rate monitor picks up your
latest OwnZone definition based on heart rate variability
(OZ.L). Alternatively, if there is no previous determination
in memory, OwnZone limits, which are based on your age
predicted maximum heart rate (OZ.A), will be used. These
methods ensure that the safest possible exercise zone is
determined for you.
The method used in defining the OwnZone is indicated
after the two beeps as follows:
1. OZ.V (OwnZone Variability) and the currently
determined OwnZone limits appear on the
illuminated display.
2. OZ.L (OwnZone Latest) and your previously
determined OwnZone limits appear on the
illuminated display.

man M91ti USA GBR A 2001

10/12/01, 13:22

3. OZ.A (OwnZone Age) and your age-predicted
heart rate limits appear on the illuminated display.
You will also see which OwnZone level you have
selected to use:
BASIC (OwnZone Basic for allround exercising)
HIGH (OwnZone High for exercising at moderate
intensity)
LOW (OwnZone Low for exercising at light to
moderate intensity)

H O W T O U S E P R E V I O U S LY
DETERMINED OWNZONE
Every time you start the stopwatch and have the OwnZone
option on, the Polar heart rate monitor 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.
OZ
appears on the display.
2. Press OK. Polar heart rate monitor starts
using your latest determined OwnZone.
OZ.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 heart rate monitor starts using your age
predicted exercising limits.
OZ.A and your age-predicted heart rate limits
appear on the illuminated display.

You can see your OwnIndex based on your latest Polar
Fitness Test and the date when it was carried out.

OWNINDEX
OwnIndex is a score which is comparable to VO2max , a
commonly used descriptor of aerobic fitness. OwnIndex is a
result of the Polar Fitness Test, which is an easy, safe and
quick way to estimate maximal aerobic power. The
OwnIndex is based on heart rate, heart rate variability at
rest, body structure and self-assessed physical activity.
Cardiovascular or aerobic fitness relates to how well your
cardiovascular system works to transport oxygen to your
body. The better the cardiovascular fitness, the stronger
and more efficient your heart is.
Having good cardiovascular fitness has many health
benefits. For example, it decreases your risk of
cardiovascular diseases, stroke and high blood pressure.
If you want to improve your cardiovascular fitness, it takes
a minimum of 6 weeks of regular training to see a
noticeable change. Less fit individuals see progress even
more rapidly and for more active individuals more time is
needed.
Cardiovascular fitness is best improved by exercise types
which use large muscle groups. Such activities include e.g.
walking, jogging, swimming, rowing, skating, cross-country
skiing and cycling.

man M91ti USA GBR A 2001

10/12/01, 13:22

TA K I N G C A R E O F Y O U R P O L A R
H E A RT R AT E M O N I T O R
• Wash the transmitter regularly after use with a mild soap
and water solution. Dry it carefully after washing.
• Never store the transmitter wet. Sweat and moisture can
keep its electrodes wet and the transmitter activated,
which shortens the battery life.
• Store your Polar heart rate monitor in a cool and dry
place. Do not store it in any kind of non-breathing
material, such as a plastic bag or a sports bag
if it is wet.
• Do not bend or stretch the transmitter. This may damage
the electrodes.
• Don’t dry the transmitter in any other way than with a
towel. Hard-handed handling may damage the
electrodes.
• Keep your Polar heart rate monitor out of extreme cold
(below 14 ºF / -10 ºC) and heat (above 122 ºF / 50 ºC).
• Do not expose the Polar heart rate monitor to direct

POLAR TRANSMITTER
The estimated average battery life of the transmitter is
2500 hours of use. Contact your distributor/ dealer for a
transmitter replacement. Polar recycles used transmitters.

POLAR WRIST RECEIVER
The estimated average battery life of the Polar wrist
receiver is 1 year in normal use (2h/ day, 7 days a week).
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 an authorized
Polar Service Center. At the same time a full periodic check
of the Polar heart rate monitor will be done.

SERVICE
Should your Polar heart rate monitor need service, see
Customer Care Charter to contact an authorized Polar
Service Center.
Water resistance cannot be guaranteed after
unauthorized service.

PRECAUTIONS
U S I N G A P O L A R H E A RT R AT E
M O N I T O R I N A WAT E R
ENVIRONMENT
Your Polar heart rate monitor is water resistant to 330 feet/
100 meters. 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 EKG 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 EKG signal.
• The EKG 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.

P O L A R H E A RT R AT E M O N I T O R
AND 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
motor driven exercise equipment, cellular phones or when
you walk through electric security gates.

man M91ti USA GBR A 2001

10/12/01, 13:22

CROSSTALK
The Polar wrist receiver in non-coded mode of operation
picks up transmitter signals within 3 feet/ 1 meter. Noncoded 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 wrist 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.

MINIMIZING POSSIBLE RISKS IN
E X E R C I S I N G W I T H A H E A RT R AT E
MONITOR
Exercise may include some risk, especially for those who
have been sedentary.
Before starting a regular exercise program an individual is
recommended to answer to the following questions for
health status checking. If the answer is yes to any of the
questions, we recommend to consult a doctor before
starting an exercise program.

Have you not exercised for the past 5 years?
Do you have high blood pressure?
Do you have high blood cholesterol?
Do you have symptoms of any disease?
Are you taking any blood pressure or heart medication?
Do you have a history of breathing problems?
Are you recovering from a serious illness or medical
treatment?
• Do you use a pacemaker or another implanted electronic
device?
• Do you smoke?
• Are you pregnant?
Note that in addition to exercise intensity, medications for
heart, blood pressure, psyche, asthma, breathing etc. as
well as some energy drinks, alcohol and nicotine, can affect
heart rate.
It is important to be sensitive to your body’s
reactions during the exercise. If you feel unexpected
pain or tiredness regarding your exercise intensity level, it is
recommended to stop the exercise or continue at a lighter
intensity.
If you are allergic to any substance that comes into
contact with the skin, check the Polar heart rate monitor
materials from the “Technical specifications” chapter. It is
recommended that you wear the transmitter against your
bare skin to ensure flawless operation. However, if you
wish to wear the transmitter over a shirt, moisten the shirt
well under the electrodes.
Notice to 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.

The combined impact of moisture and intense
abrasion may cause a black color, which might stain
light-colored, clothes especially, to come off the
transmitter's surface.

FREQUENTLY ASKED QUESTIONS
W H A T S H O U L D I D O I F. . .
...I DON'T KNOW WHERE I AM IN THE OPTIONS OR FILE
CYCLE?
Press and hold the OK button until time of day is displayed.
... 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 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 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 receiver,
such as TV sets, mobile phones, CRT monitors etc.
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).

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:
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.
... THERE ARE NO REACTIONS TO ANY BUTTONS?
Reset the Polar heart rate monitor. Resetting clears watch
settings which will return to the default settings. User
information and measurement options settings will be
saved.
1. Press the RESET button with a pen tip.
Display becomes full of digits.
2. Press any of the four button once.
The Polar heart rate monitor enters the Time of Day
display.
If you don’t press any button after reset within one minute
the wrist receiver goes to the battery saving mode.
... THE DISPLAY IS BLANK OR FADING?
The Polar heart rate monitor is in battery saving mode
when it leaves the factory. Wake up by pressing the OK
button twice.
The Polar heart rate monitor enters the Time of Day
display.

man M91ti USA GBR A 2001

10/12/01, 13:22

Usually the first sign of a discharged battery is fading of
the digits when using the backlight. Have the batteries
checked.
... THE BATTERY OF THE WRIST RECEIVER MUST BE
REPLACED?
We recommend having all service done by an authorized
Polar Service Center. This is especially necessary to ensure
the warranty remains valid and is not affected by incorrect
repair procedures done by an unauthorized 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.

POLAR GLOSSARY
Coded heart rate transmission: Polar coded transmitter
automatically locks in a code to transmit your heart rate to
your wrist receiver. In coded transmission the receiver
accepts heart rate from your transmitter only. Coding
significantly reduces crosstalk caused by other users of
heart rate monitors. However, it does not necessarily
reduce all environmental interference.
Electrodes: The grooved areas of the transmitter, against
the skin. Pick up the heart’s electrical impulses.
Heart rate: The number of heart beats per minute (bpm)
Heart rate variability: Fluctuations of interbeat intervals.
Heart rate variability of a healthy subject is in general large
in resting conditions and during light exercise. Heart rate
variability gradually disappears when exercise becomes
more intense and heart rate increases.
Target zone, TZ: The area between the upper and lower
target zone limits. Can be defined automatically by Polar
heart rate monitor or manually by yourself.
DISPLAY SYMBOLS
Indicates coded transmission of heart rate. The inner
heart flashes to the beat of your heart.
In the Time of day mode indicates that the alarm is
on. In the measure mode indicates that the sound
signal will alarm if you are exercising outside your
Target Zone.
Progress bullets in the measure mode.
One bullet = 10 minutes in target zone.
Indicates OwnZone determination procedure.
Measure mode, heart rate measurement is on.
Exercise mode, stopwatch is on.
