Installing the Polar S1 foot pod  
Easy start  
First, make sure that there is a battery in the foot pod. You can check this by  
pressing and holding the red button on the foot pod. If a green light starts  
to flash, you can start attaching the foot pod on your shoe. If there is no  
light, start from the chapter Assembling the S1 foot pod battery.  
How to prepare the wrist unit  
1. Since the display is blank when the wrist unit leaves the factory, you have  
to activate the wrist unit 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 wrist unit you can not turn it off anymore.  
Assembling the S1 foot pod battery  
The estimated average battery life span of the foot pod is 20 hours of use. If  
you prefer Polar to replace the battery, you can send or take the sensor to a  
Polar Service Center. There the sensor is tested after the battery is replaced.  
However, the S1 foot pod was designed so that you can replace the battery  
yourself. If you do so, follow the instructions below carefully:  
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).  
1. Detach the foot pod from its holder by unfastening the flap and lifting  
the foot pod from the rear.  
2. Remove the black top cover from the

3. Open the battery cover carefully. Pull out  
3
the battery case. (See picture 3.) Replace  
the old battery (AAA) with a new one.  
4. Insert the battery case back inside the foot pod. Make sure that the  
battery case slides into the grooves of the sensor. Be careful not to touch  
the switch on the foot pod (see the arrow in picture 3).  
5. Check that the sealing rings are in the grooves. Close the battery cover  
and place the black top cover on top of the foot pod. Make sure that it is  
secured.  
4. Wear the wrist unit as you would wear an ordinary watch. If you go  
biking, we recommend attaching the wrist unit to the accessory Polar  
Bike Mount.  
6. Test the foot pod by checking that the green light starts to flash after  
you press and hold the red button on the foot pod. Press and hold the  
red button again to turn the foot pod off.

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.  
All that you can do with your running/cycling computer  
Here is a short overview of the modes of the wrist unit and the different  
functions they offer you.  
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.  
1. TIME OF DAY  
In this mode you can use your wrist unit as a watch since it can display  
the time, date, weekday, alarm and two different time zones. In addition,  
you can download a personal logo, user number or user name from  
download 7 reminders with alarms.  
How to stop measuring your heart rate  
1. Press the stop button. The stopwatch and other calculations stop.  
The heart rate measuring continues, although exercise data is no longer

3. RECORDING MODE (SEE SECTION C. EXERCISE)  
In Recording mode your exercise is recorded and stopwatch and other  
calculations are started. You can use the BasicUse function when you  
just want to exercise without setting target limits, timers or other  
exercise settings. If you use the settings mentioned above, you can  
program up to five exercise sets for different kind of exercises.  
1. To detach the connector from the strap, apply  
pressure with your thumb and forefinger and  
turn your hand as indicated in the picture.  
2. Carefully wash the strap with a mild soap and  
water solution. 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.  
 
14  
15  
A. BasicUse is the easiest way to start exercising because you do not  
have to set different target limits or timers. You just start in Measuring  
mode and choose BasicUse and you are ready to go. You can select  
among several different heart rate, running or cycling information  
alternatives for the display of your wrist unit.  
4. FILE (SEE SECTION D. HOW TO RECALL TRAINING INFORMATION)  
In this mode you can recall your training information. Your wrist unit  
saves up to 99 files of exercise information when you use the Recording  
mode (stopwatch on). For more information about the recorded training  
information, see chapter D. How to Recall Training Information.  
B. Freely programmable BasicSet offers you the possibility to set  
three functions to control your exercise session.

types)  
5. OPTIONS (SEE SECTION B. HOW TO ENTER SETTINGS)  
In the Options mode you set all your personal settings for optimal use of  
your running/cycling computer. It is highly recommended that you enter  
all your personal settings in your wrist unit before you start to use your  
running/cycling computer for the first time. By doing so, you guarantee  
the optimal functioning of your running/cycling computer. You can also  
use the Polar Precision Performance software to set and transfer your  
personal settings from your PC to your wrist unit.  
2. Three adjustable alternating timers.  
3. Time-based or heart rate-based recovery calculation. By using these  
functions, you can easily control your normal exercise session. You  
can program several different kinds of exercise sets. When training,  
choose the one that suits the training you plan to do best.  
6. TESTS (SEE SECTION E. TESTS)  
C. Freely programmable Interval Trainer automatically guides you  
through your interval training session. You can program the following  
exercise phases:  
In this mode you can carry out the Polar Fitness and OwnOptimizer™  
Tests.  
1. warm-up period with target limits and a countdown timer  
2. up to 30 intervals with target limits and an option for a recovery  
calculation after each interval  
3. a cool-down period, using a countdown timer after intervals  
Use of this Interval Training function leaves you free to concentrate  
on your exercise during the interval training. Your wrist unit takes  
care of observing timers and limits, all you have to do is exercise.  
Polar Fitness Test estimates your maximal aerobic power (VO2max) and  
shows the result as a Polar OwnIndex value. This test also provides a  
predicted maximum heart rate value (HRmax-p). The Polar Fitness Test is  
designed to monitor your personal progress. You should do the test  
regularly to see the changes in your cardiovascular fitness. Your wrist  
unit will memorize your last OwnIndex value.

OwnIndex  
OwnIndex is a value which is comparable to maximal oxygen uptake (VO2max ),  
a commonly used descriptor of aerobic fitness. Cardiovascular (aerobic)  
fitness relates to how well your cardiovascular system works to transport  
and utilize oxygen in your body. The stronger and more efficient your heart  
is, the better the cardiovascular fitness is. VO2max is a good indicator of  
performance in endurance sports.  
*Optional Polar Cadence Sensor or Polar Power Output Sensor required.  
 
84  
85  
If you want to improve your cardiovascular fitness, it takes a minimum of  
6 weeks on an average to see a noticeable change in OwnIndex. Less fit  
individuals see progress even more rapidly and for more fit individuals  
more time is needed.  
Predicted maximum heart rate (HRmax-p)  
The HRmax-p definition is carried out simultaneously with the Polar Fitness  
Test.  
The HRmax-p score predicts your individual maximum heart rate value more  
accurately than the age-based formula (220 - age). The age-based method  
provides a rough estimation and is thus not very accurate, especially for  
people who have been fit for many years or for older people. The most  
accurate way of determining your individual maximum heart rate is to have  
it clinically measured (in maximal treadmill or bicycle stress test) by a  
cardiologist or an exercise physiologist.  
Cardiovascular fitness is best improved by exercise types which employ  
large muscle groups. Such activities include running, swimming, rowing,  
skating, cross-country skiing, cycling and walking.  
To monitor your fitness progress start with measuring your OwnIndex a  
couple of times during the first two weeks, to get a baseline value.  
Thereafter, repeat the test approximately once a month.  
OwnIndex is based on resting heart rate, heart rate variability at rest, age,  
gender, height, body weight and self-assessed physical activity.  
Your maximum heart rate changes to some extent in relation to your  
fitness. Regular exercise tends to decrease HRmax whereas reduced training  
tends to increase it. There may also be some variation according to the  
sport you participate in. For example, running HRmax > cycling HRmax  
swimming HRmax  
>
.
HRmax-p gives the possibility of defining training intensities as percentages  
of maximum heart rate and of following maximum heart rate changes due  
to training, without an exhaustive maximal stress test. HRmax-p is based on  
resting heart rate, heart rate variability at rest, age, gender, height, body  
weight and maximal oxygen uptake, VO2max (measured or predicted). The  
most accurate HRmax-p is obtained by entering your clinically measured  
VO2max into the wrist unit.

For various fitness classes we recommend the following:  
Training Optimizer

Successful training requires temporary overloading: longer exercise  
duration, higher intensity, or higher total volume. In order to avoid severe  
overtraining, overloading must always be followed by an adequate  
recovery period. With an inadequate recovery period, you may experience a  
decrease in performance as a result of high training volumes, instead of  
improvement. Polar OwnOptimizer is an easy and reliable way to  
determine whether your training program is optimally developing your  
performance.

OwnOptimizer

Polar OwnOptimizer is a modification of a traditional orthostatic  
overtraining test. It is a perfect tool for everyone training regularly, at least  
three times a week, for fitness improvement or to reach competitive  
targets. This feature is based on heart rate and heart rate variability  
measurements taken during an orthostatic test (standing up from relaxed  
resting). OwnOptimizer helps you to optimize your training load during a  
training program so that you experience an increase in performance and do  
not undertrain or overtrain over the long-term.  
1
Top athletes typically score OwnIndex values above 70 (men) and 60  
(women). As high values as 95 can be reached by Olympic level athletes.  
OwnIndex is highest in sports that involve large muscle groups such as  
cross-country skiing and cycling.  
Polar OwnOptimizer is based on regular long-term measurements of five  
heart rate parameters. Two of these five values are calculated at rest, one  
while standing up and two while standing. Each time you perform the test,  
the wrist unit saves the heart rate values and compares them to the  
previous values registered.  
 
92  
93  
Baseline tests  
To get reliable test results, the following basic requirements apply:  
When you start using OwnOptimizer for the first time, six baseline tests  
should be conducted over a period of two weeks to determine your  
personal baseline value. These baseline measurements should be taken  
during two typical basic training weeks, not during heavy training weeks.  
The baseline measurements should include tests taken after training and  
after recovery days.  
-
-
-
You should be relaxed and calm.  
Avoid eating, drinking and smoking 2-3 hours prior to the test.  
The test can take place anywhere – at home, in the office, at a health  
club – as long as the test environment is peaceful. There should be no  
disturbing noises (for example, television, radio or telephone) or other  
people talking to you.  
-
You can be seated in a relaxed position or lying in bed. The position  
should always be the same when you do the test.  
Monitoring your OwnOptimizer values  
After the baseline recordings, you should continue to perform the test 2-3  
times a week. Test yourself weekly in the morning following both a  
recovery day and a heavy training day (or a series of heavy training days).  
An optional third test can be performed after a normal training day.  
Wear the transmitter and the wrist unit as described in the "Easy start"  
section.

train for one or two days, or 2) continue intensive training for one or  
two days and then recover well.  
Other sources of stress, the beginning of a fever or an attack of the flu  
can result in the same kind of response.  
If the test fails, the wrist unit gives a signal and the text "Failed test" is  
displayed. You can retake the test by starting from the very beginning.  
Steady / Steady Training State (4)  
Your test heart rates have continuously been at a normal level for a  
long time now. Effective training requires both heavy training and good  
recovery, and this should cause variation in your test heart rates. Your  
OwnOptimizer Test indicates that you have not had very intensive  
training or good recovery for a while. Perform the test again after a rest  
or light training day. If the recovery is effective, you will get Recovered  
as a test result.  
How to interpret the results  
The wrist unit calculates five heart rate and heart rate variability based  
parameters. The OwnOptimizer values are calculated by comparing your  
latest results to your previous results. The wrist unit will display a written  
description of your training status. They are defined in detail below. The  
wrist unit also displays your average heart rate (bpm) while lying down  
(Rest HR), the highest heart rate while standing up (Peak HR) and the  
average heart rate while standing (Stand HR).  
Stagnant / Stagnant Training State (5)  
Your test heart rates are still at a normal level, and this has continued  
for a long time. Your test indicates that your training has not been  
intensive enough to develop optimally. To improve your condition most  
effectively, you should now include more intense or longer exercise  
sessions in your training.  
The display texts for interpretation of your OwnOptimizer values are:  
Recovered / Recovered (1)  
Your test heart rates are lower than average. This indicates that you  
have recovered very well. You can continue training, including intensive  
exercise sessions.  
Hard Tr / Hard Training Effect (6)  
Your test heart rates have been higher than average several times. You  
may have trained hard on purpose. Your test indicates overloading, and  
you should recover well now. To control your recovery, perform the test  
again after one or two resting or easy training days.  
Normal / Normal Training State (2)  
Your test heart rates are at a normal level. Go on with your training;  
include both light and intensive training sessions, and recovery days.  
 
96  
97  
To recover from a state of parasympathetic overtraining, you have to  
recover your body balance completely. Recovering may take several weeks.  
You should not exercise, and instead rest completely for most of the  
recovery period. You can possibly have a few days with some light aerobic  
training in short sessions, and only occasionally include short, high intensity  
sessions. You can also consider some other sport than your main sport.  
However, it should be one you are familiar and feel comfortable with.  
Control your recovery with OwnOptimizer Test by performing the test  
2 – 3 times per week. If you feel that you have recovered your body balance  
and you get Normal Training State or Recovered as a test result, preferably  
more than once, you can consider continuing your training. When you  
can start training again, you should start a new testing period with new  
baseline measurements.  
OverReach / Overreaching (7)  
Your OwnOptimizer Test indicates that you have had a very intensive  
training period for several days or weeks. Your test heart rates have  
continuously stayed at a high level. This seriously indicates that you  
should have a complete recovery period. The longer you have trained  
intensively, the longer the recovery period required to recover. Perform  
the test again after at least two days of recovery.  
OverTrS / Sympathetic Overtraining (8)  
Your OwnOptimizer Test indicates that you have had a very intensive  
training period for several days or weeks, and your recovery has not  
been sufficient. This has result in a state of overtraining. To get back to  
a normal training state, you have to rest for a carefully controlled  
recovery period. Control your recovery with OwnOptimizer Test by  
performing the test 2 – 3 times per week.  
Note  
Before you radically change your training program, consider your OwnOptimizer  
results together with your subjective feelings and the symptoms you have.  
You should repeat the OwnOptimizer test if you are unsure of the standardized  
conditions. An individual test result can be affected by several external factors,  
such as mental stress, latent illness, environmental changes (temperature,  
altitude) and others.  
OverTrP / Parasympathetic Overtraining (9)  
Your heart rates have stayed at a low level, which is generally interpreted  
as a sign of a good recovery. However, other parameters indicate  
parasympathetic overtraining. You may have trained with high volumes  
for a long time and your recovery times may not have been long enough.  
You should check if you have other signs of overtraining. For example,  
overtraining is marked by decreased performance, increased fatigue,  
mood disturbances, sleeping problems, persistent muscle soreness and/  
or a feeling of being burnt out or stale. You may also have been  
subjected to other stresses.  
You should update the baseline calculations at least once a year when you  
start a new training season.  
Analyzing the result with the PC software  
If you download the results of the test from your wrist unit to the PC, you  
can analyze the results with the Polar Precision Performance software. The  
software offers you various ways to analyze the results and receive more  
detailed information about your progress. You can also generate graphical  
comparisons with your previous values.  
In general, the development of parasympathetic overtraining requires a  
long history of heavy training volumes.

F. CARE AND MAINTENANCE  
You can wash the strap in a washing machine at +40 °C / 104 °F.  
We recommend that you use a washing pouch.  
We recommend that you wash the strap after each time you have  
used it in pool water with a high chlorine content.  
Do not spin-dry the strap!  
Your Polar running/cycling computer is a high-tech instrument  
of superior design and workmanship and should be treated  
with care. The suggestions below will help you fulfill the  
guarantee obligations and enjoy this product for many years  
to come.  
Do not put the strap in a dryer!  
Do not iron the strap!  
Keep the air pressure channels (three openings on the wrist unit  
backcover) clean to make sure that the altitude and temperature  
measurements work. Do not insert any objects into the openings.  
Wipe dry the Polar S1 foot pod.  
Avoid hard hits to the S1 foot pod as these may cause damage.  
Do not immerse the speed sensor in water.  
Taking care of your Polar running/cycling computer  
Store your wrist unit and transmitter 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. Sweat and moisture can keep the transmitters  
electrodes wet and the transmitter activated, which shortens the battery  
life.  
Avoid hard hits to the speed sensor as these may cause damage.  
Keep your wrist unit and transmitter out of extreme cold (below -10 ºC /  
14 ºF) and heat (above +50 ºC / 122 ºF).  
Do not expose the wrist unit and transmitter to direct sunlight for  
extended periods, such as by leaving it in a car.  
If you use insect repellent on your skin, you must ensure that it does not  
come into contact with the transmitter!  
Detach the connector from the strap when not in use.  
Clean the connector regularly after use with a mild soap and water solution.  
Never use alcohol or any abrasive material such as steel wool or cleaning  
chemicals on any part of the transmitter.  
Batteries  
Transmitter  
The estimated average battery life span of the transmitter is 2 years  
(1h/ day, 7 days/ week). If your transmitter stops working, it might be  
due to the battery running out. We recommend that you have the  
battery replaced by an authorized Polar Service Center only.  
You can, however, change the battery yourself by following the  
instructions below. To change the battery, you need a coin, a sealing  
ring and a battery (CR2025).  
Do not dry the connector in any other way than with a towel. Rough  
handling may damage it.  
Never put the connector in a washing machine or a drier!  
 
100

Speed Sensor  
3. Remove the sealing ring of the battery cover and replace it with a new  
ring.  
4. Place the negative (-) side of the battery against the connector and the  
positive (+) side against the cover.  
5. Put the battery in the connector's niche and put the cover on so that the  
arrow points to the OPEN position. Make sure that the cover's sealing  
ring is placed correctly in its groove.  
6. Gently press the cover deep enough so that its exterior surface is on the  
same level as the connector's surface.  
The estimated average battery life of the speed sensor is 2500 hours of  
use. We highly recommend you send the speed sensor to an authorized  
Polar Service Center for battery replacement, where the unit is tested  
after the battery has been replaced. However, if you prefer changing  
the battery yourself, please follow these instructions carefully:  
Detach the sensor from your bicycle.  
1. Open the sensor by removing the two small screws, counterclockwise,  
with a small screwdriver.  
2. Lift the case off carefully. Hold the sensor cover upwards so that the  
PCBA (printed circuit board assembled) stays in the case.  
3. Remove the PCBA carefully.  
7. Turn the cover clockwise so that the arrow on the cover turns from OPEN  
to CLOSE. Make sure that the cover is closed properly!  
4. Press the battery holder gently. Release a hook of the holder from  
the opposite side of the PCBA and lift the holder upwards. Remove  
the old battery.  
5. Insert a new battery with the plus (+) side facing up and press the  
battery housing gently so that it is attached to the PCBA at all corners.  
In order to ensure the maximum life span of the connector’s battery  
cover, open it only when you need to change the battery. We  
recommend that you change the sealing ring of the battery cover every  
time you change the battery. You can get the sealing ring/battery kits  
from well-equipped Polar retailers and authorized Polar Services. In the  
USA and Canada: Additional sealing rings are available from an  
authorized Polar Service Center only.  
 
102  
103  
G. PRECAUTIONS  
6. Put the PCBA back into place.  
Using the Polar running/cycling computer in a water environment  
7. Check that the sealing ring stays in its groove. Replace the cover back.  
8. Insert the two screws in their holes and tighten them gradually in turn.  
9. Test the sensor by checking that it gives out an orange flash when the  
spoke magnet passes the speed sensor.  
10. Do not throw the replaced battery away with normal waste; take it to  
a place where problem waste is handled.  
Your Polar running/cycling computer can be worn when swimming.  
To maintain the water resistance, do not operate the buttons of the  
wrist unit under water.  
Users measuring their heart rate in water may experience interference for  
the following reasons:  
Wrist unit  
Pool water with a high chlorine content and seawater are very  
conductive. The electrodes of a Polar transmitter may short circuit, which  
prevents the transmitter unit from detecting ECG signals.  
Jumping into 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 an ECG signal.  
ECG signal strength is individual and also varies depending on an  
individual’s tissue composition. The percentage of people who have  
problems measuring their heart rate is considerably higher in water than  
in other environments.  
The estimated average battery life of the wrist unit is 2 years 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 unit yourself. To ensure the water resistance properties and  
the use of qualified components, the wrist unit battery should be replaced  
only by an authorized Polar Service Center. At the same time a full periodic  
check of the Polar running/cycling computer will be done.  
Batteries should be disposed of properly according to local regulations.  
Service  
The S1 foot pod can be worn e.g. when raining, but it is not intended  
for underwater use.  
Should your Polar running/cycling computer need service, see Customer  
Care Charter to contact an authorized Polar Service Center.  
Water resistance cannot be guaranteed after unauthorized service.

105  
Polar running/cycling computer and interference  
Minimising possible risks in exercising  
Exercise may include some risk, especially for those who have been sedentary.  
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 or  
when you walk through electric security gates. In some cases, mobile  
phones may cause interference when starting the heart rate measurement.  
Before starting a regular exercise program you are recommended to  
answer to the following questions for health status checking. If the answer  
is yes to any of the questions, we recommend that you consult a doctor  
before starting an exercise program.  
Have you been physically inactive for the past 5 years?  
Do you have high blood pressure?  
Do you have high blood cholesterol?  
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 unit as follows:  
1. Remove the transmitter from your chest and use the exercise equipment  
as you would normally.  
2. Move the wrist unit 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 unit in this  
interference-free area as far as it is possible.  
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, heart, blood pressure, psyche,  
asthma, breathing etc. medication as well as some energy drinks, alcohol  
and nicotine, can affect heart rate.  
4. If the Polar running/cycling computer still does not work with the  
exercise equipment, this piece of equipment may be electrically too  
noisy for wireless heart rate measurement.  
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.  
 
106  
107  
H. FREQUENTLY ASKED QUESTIONS  
Notice to persons with pacemakers, defibrillator or other  
implanted electronic device. Persons who have a pacemaker use the  
Polar running/cycling computer 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 running/cycling computer.  
What should I do if...  
...I don’t know where I am in the Options or File cycle?  
Press and hold the stop button until time of day is displayed.  
...I cannot find the expended calories from my exercise file?  
Check that you have set your personal user information and turned the  
OwnCal function on. Check that your heart rate has reached over 90 bpm  
or above 60 % of your maximum heart rate during your exercise.  
If you are allergic to any substance that comes into contact with  
the skin or if you suspect an allergic reaction due to using the  
product, check the listed materials in the "Technical specifications"  
chapter. To avoid any skin reaction risk with the transmitter, wear it over a  
shirt. However, moisten the shirt well under the electrodes to ensure  
flawless operation.  
...I cannot turn my HRmax-p on?  
Check that you have set your personal user information and turned the  
Fitness Test on before turning the HRmax-p on.  
...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 you are not near other people that have heart rate monitors,  
high voltage power lines, televisions, mobile phones or other sources of  
electromagnetic disturbance.  
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.  
Your safety is important to us. The shape of the foot pod is designed to  
minimize the possibility of it being caught. Anyhow, take caution when  
running with the foot pod for example in brushwood.  
4. Have you had a cardiac event which may have altered your ECG  
waveform? In this case consult your physician.  
...heart symbol flashes irregularly?  
1. Check that the wrist unit is not further than 1 meter/ 3 feet from the  
transmitter.  
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  
1 meter/ 3 feet.  
 
108  
109  
5. Cardiac arrhythmia may cause irregular readings. In this case consult  
your physician.  
2. Press any of the buttons once. Time of day is displayed.  
...the battery of the wrist unit must be replaced?  
...other person with heart rate monitor is causing interference?  
Your training partner may have exactly the same code as you. In this case  
proceed as follows: Keep a distance from your training partner and  
continue your training session normally.  
We recommend having all service done by an authorized Polar Service  
Center. The guarentee does not cover damage or consequential damage  
caused by service not authorized by Polar Electro. Polar Service will test  
your wrist unit for water resistance after battery replacement and make a  
full periodic check of the complete Polar running/cycling computer.  
Or  
1. Take the transmitter off your chest for 30 seconds. Keep a distance from  
your training partner.  
2. Put the transmitter back and bring the wrist unit up to your chest near  
the transmitter’s Polar logo. The wrist unit starts looking for a heart rate  
signal again. Continue your training session normally.  
...there are irregular speed or distance readings?  
1. Check that the user settings of the wrist unit are set correctly.  
2. You may have come within range of strong electromagnetic-signals,  
which cause erratic readings.  
3. Keep distance to other persons with foot pod or speed sensor.  
...heart rate reading becomes erratic or extremely high?  
You may have come within range of strong electromagnetic signals which  
cause erratic readings. Check your surroundings and move further away  
from the source of disturbance.  
...inaccurate altitude readings?  
The influence of a sudden temperature change (i.e., if you go outdoors in the  
winter) may cause temporarily inaccurate altitude readings. We recommend  
that you place the wrist unit on your wrist at least 15 minutes before starting  
the exercise, so the wrist unit gets adjusted to the surrounding temperature.  
If the readings are constantly inaccurate, it may be caused by dirt blocking  
the air pressure channels (three openings on the backover and two on the  
side of the wrist unit). In this case, send the running/cycling computer to a  
Polar Service Center.  
...the display is blank or fading?  
If the display is blank, activate the wrist unit by pressing the OK button  
twice, after which the Time of day display appears. The first sign of a  
discharged battery is the battery symbol on the display. Also the digits fade  
when the backlight is used. Have the batteries checked.  
...there are no reactions to any buttons?  
...the data transfer from wrist unit to PC was unsuccessful?  
1. Check the correct position of the wrist unit with the infrared window of  
the PC or the optional interface.  
2. Check that the surroundings are not too bright. This problem often  
occurs near windows.  
Reset the Polar running/cycling computer. Resetting clears watch settings  
which will return to the default settings. User information and measuring  
units settings will be saved.  
1. Press the RESET button with a pen tip. Display becomes full of digits.  
If you don’t press any button after reset within one minute the wrist  
unit returns to the Time of day display.  
3. Check that there is no obstruction between the infrared windows.

K. POLAR DISCLAIMER  
L. POLAR GLOSSARY  
Activity level:  
Coded heart rate transmission:  
Polar coded transmitter automatically  
locks in a code to transmit your  
heart rate to the wrist unit. In a  
coded transmission the wrist unit  
accepts heart rate data only from  
the Polar coded transmitter. Coding  
significantly reduces crosstalk  
caused by other users of heart rate  
monitors. However, it does not  
necessarily reduce all environmental  
interference.  
The material in this manual is for informational purposes only. The  
products it describes are subject to change without prior notice, due to  
the manufacturer’s continuous development program.  
Your long-term physical activity level  
you need to assess in order to do the  
Polar Fitness Test.  
Polar Electro Inc. / Polar Electro Oy makes no representations or  
warranties with respect to this manual or with respect to the products  
described herein. Polar Electro Inc. / Polar Electro Oy shall not be liable  
for any damages, losses, costs or expenses, direct, indirect or incidental,  
consequential or special, arising out of, or related to the use of this  
material or the products described herein.  
Altitude and temperature:  
The altitude and temperature are  
measured by using an atmospheric  
pressure sensor. Air pressure changes  
constantly due to various weather  
conditions and therefore the  
calculated altitude of a certain spot  
may differ. Variation of high and low  
pressure or air conditioning can cause  
a change in the altitude reading.  
For example, a thunderstorm can  
cause a change of up to 80 mbars,  
which means a change of  
approximately 700 m/ 2000 ft in the  
calculated altitude. Therefore, it is  
recommended that you adjust the  
exact starting point altitude whenever  
a reliable reference; for example, a  
peak pointer or a map, is available. It  
is also recommended that you check  
the altitude of your house and other  
common starting points for training.

e.g. in nutrition planning. OwnCal  
calorie calculation starts when your  
heart rate reaches 90 bpm or is above  
60% of your maximum heart rate,  
whichever is smaller. These limits are  
set to count only exercise calories.  
The higher the heart rate, the faster  
the energy expenditure. OwnCal is  
individually calibrated by your preset  
weight, maximal oxygen uptake  
(VO2max ) and maximum heart rate  
(HRmax). The most accurate OwnCal is  
received by entering your clinically  
measured (in maximal treadmill or  
bicycle stress test) VO2max and HRmax  
into the wrist unit. Energy  
expenditure measurement is most  
accurate in continuous activities such  
as cycling and running.

Accessories  
Polar Cadence Sensor:  
A wireless sensor that measures the frequency at which you  
turn the pedals of your bicycle.  
Power Output Sensor:  
The Polar Power Output system measures pedaling power  
when cycling. It also measures left/right balance (LRB  
describes the share of power output of left and right as a  
percentage), pedaling index (describes how evenly power  
output was produced during a cycle round), speed, cadence  
and distance. If you use the Power Sensor, you do not need  
to mount any other accessories on your bicycle.  
Polar MobileLink Application  
The Polar MobileLink application enables infrared  
communication between the Polar S625X and Polar S725X,  
and a compatible Nokia mobile phone. You can transfer  
data from your wrist unit and quickly analyse your  
performance in graphical format on the phone's bright  
colour screen. Mobile connectivity allows you to share your  
experience with your friends or coach by SMS, or forward  
your activity data to the Polar PC Software or Web Service  
for further analysis and longer-term follow-up. Check  
www.polar.fi/mobilelink to learn more about the Polar  
MobileLink application; you will also find a list of  
compatible phone models and instructions on how to  
download the application.
