GET STARTED
SET UP YOUR A370
When you get hold of your new A370, it’s in storage mode. It wakes up when you
plug it into a computer for setup or a USB charger for charging. We recommend
that you charge the battery before you start using your A370. If the battery
is completely empty, it takes a couple of minutes for the charging to start.
See Batteries for detailed information on charging the battery, battery
operating times and low battery notifications. CHOOSE ONE OPTION FOR SETUP:
COMPUTER OR A COMPATIBLE MOBILE DEVICE You can choose how to set up your A370,
with a computer and a USB cable or wirelessly with a compatible mobile device.
Both methods require an Internet connection.
l Mobile setup is convenient if you don’t have access to a computer with a USB
port, but it might take longer.
l Wired setup is quicker and you can charge your A370 at the same time, but
you need a USB cable and computer available.
OPTION A: SET UP WITH YOUR COMPUTER 1. Go to flow.polar.com/start and install
the FlowSync software to set up your A370 and update the firmware if needed.
2. Push down the top part (A) of the USB cover inside the bracelet to access
the micro USB port and plug in the supplied USB cable (B). Don’t charge the
device when its USB port is wet. If the USB port of your A370 has gotten wet,
let it dry up before plugging in.
3. Plug the other end of the cable into the USB port of your computer for
setup and charging the battery
11
(C).
4. Then we’ll walk you through signing up for the Polar Flow web service and
personalizing your A370. To get the most accurate and personalized activity
and training data, it’s important that you’re pre-
cise with the physical settings when signing up for the web service. When
signing up, you can choose a language and get the latest firmware for your
A370. When closing the USB cover, make sure it fits flush on the device. After
the setup is done, you’re ready to go. Have fun! OPTION B: SET UP WITH POLAR
FLOW APP USING YOUR MOBILE DEVICE OR TABLET Polar A370 connects to the Polar
Flow mobile app wirelessly via Bluetooth Smart, so remember to have it turned
on in your mobile device. 1. To make sure there’s enough charge in your A370
during the mobile setup, just plug the USB cable in a powered USB port or a
USB power adapter. Make sure that the adapter is marked with “output 5Vdc” and
that it provides a minimum of 500mA. The display begins to show an animated
circle with Bluetooth and USB icons.
Don’t charge the device when its USB port is wet. If the USB port of your A370
has gotten wet, let it dry up before plugging in.
12
2. Go to the App StoreSM or Google PlayTM on your mobile device and search
and download the Polar Flow app. The mobile compatibility is available at
support.polar.com.
3. When you open the Flow app it recognizes your new A370 nearby and prompts
you to start pairing it. Accept the pairing request and enter the Bluetooth
pairing code from your A370 to the Flow app. Make sure your A370 is powered up
in order to make the connection possible.
4. Then create an account or sign in if you already have a Polar account.
We’ll walk you through the signup and setup within the app. Tap Save and sync
when you’ve defined all the settings. Your personalized settings will now be
transferred to the bracelet. To get the most accurate and personal activity
and training data, it’s important that you’re precise with the settings.
Please notice your A370 may get the latest firmware update during the wireless
setup, and depending on your connection it may take up to 20 minutes to
complete. Your A370 will receive the language package according to your
selection in the setup and it will also take some time.
5. A370 display will open to the time view once the synchronization is done.
You’re ready to go, have fun!

23
TRAINING
HOW TO WEAR YOUR A370
A370 continuously measures heart rate from the wrist, in everyday-wear and
during exercises. To get accurate heart rate readings, find a comfortable fit
for your wrist by following these tips. In everyday-wear, secure the wrist
band on top of your wrist, behind the wrist bone. Do NOT place the fitness
tracker on top of the wrist bone. The band can be slightly loose as long as
the sensor on the back is touching your skin and stays in place when you move.
Tighten the band a little bit when you start a training session, so the sensor
will not move when you exercise. The wrist band should not be uncomfortably
tight either. Remember to loosen the wrist band after training for a more
comfortable fit.
If you have tattoos on the skin of your wrist, avoid placing the sensor right
on it as it may prevent accurate readings. Also it’s a good idea to warm up
the skin if your hands and skin get cold easily. Get the blood going before
starting your session! In sports where it’s more challenging to keep the
sensor stationary on your wrist or where you have pressure or movement in
muscles or tendons near the sensor, we recommend using a Polar H10 heart rate
sensor with a chest strap to get better measurement of your heart rate. Follow
your heart rate zones directly from your device and get guidance for training
sessions you’ve planned in the Flow web service. Although there are many
subjective clues as to how your body is doing during exercise (perceived
exertion, breathing rate, physical sensations), none of them are as reliable
as measuring heart rate. It is objective and is affected by both internal and
external factors – meaning you will have a dependable measure of your physical
state.
24
START A TRAINING SESSION
In the time view, swipe the display up or down and tap Training to enter pre-
training mode: a heart icon turns to display your heart rate when it’s been
found and if you use your mobile’s location, the GPS icon’s circle becomes
static when the location has been found.
Choose the sport profile you want to use by swiping up or down.
Tap the chosen sport icon to start the session.

your A370 during training. To pause a training session, press the button.
Paused is displayed and the A370 goes to pause mode. To continue your training

to end the recording.
START A TRAINING SESSION WITH A TARGET

name/profile photo in the upper right corner and go to the Daily Activity goal
tab in Settings. The Daily Activity goal setting lets you choose the one that
best describes your typical day and activity from three activity levels. Below
the selection area, you can see how active you need to be to reach your daily
activity goal on the chosen level. For example, if you’re an office worker and
spend most of your day sitting, you would be expected to reach about four
hours of low intensity activity during an ordinary day. For people who stand
and walk a lot during their working hours, the expectations are higher.
ACTIVITY DATA
A370 gradually fills up an activity bar to indicate your progress towards your
daily goal. When the bar is full, you’ve reached your goal and you’ll get a
vibrating alert. You can view the activity bar in My day menu and in some of
the watch faces. In the My day menu you can see how active your day has been
so far along with any training sessions you’ve done or planned for the day.
l Steps: Steps you’ve taken so far. The amount and type of body movements are
registered and turned into an estimation of steps.
l Calories: Shows how many calories you’ve burned through training, activity
and BMR (Basal metabolic rate: the minimum metabolic activity required to
maintain life).
Note that your training session information is not included in the daily
activity data. In other words, the steps, the distance, the active time and
the calories as well as the overall progress towards reaching your daily
activity goal that are shown under the My day menu on your fitness tracker,
and under Activity in the Polar Flow mobile app and web service, represent all
the other activity you perform during the day, in addition to any recorded
training session.

INACTIVITY ALERT
It’s widely known that physical activity is a major factor in maintaining
health. In addition to being physically active, it’s important to avoid
prolonged sitting. Sitting for long periods of time is bad for your health,
even on those days when you train and gain enough daily activity. Your A370
spots if you’re being inactive for too long during your day and this way helps
you to break up your sitting to avoid the negative effects it has on your
health.
If you’ve been still for 55 minutes, you’ll get an inactivity alert: It’s time
to move is shown along with a small vibration. Stand up and find your own way
to be active. Take a short walk, stretch, or do some other light activity. The
message goes away when you start moving or press any button. If you don’t get
active in five minutes, you’ll get an inactivity stamp, which you can see on
the Flow app and Flow web service after syncing.
Both Flow app and Flow web service will show you how many inactivity stamps
you have received. This way you can check back on your daily routine and make
changes towards a more active life.
SLEEP INFORMATION IN THE FLOW WEB SERVICE AND FLOW APP
Polar devices with 24/7 activity measurement automatically detect when you
fall asleep, when you’re sleeping and when you wake up from your wrist
movements. They observe your movements during the night tracking all
interruptions during your sleep span, and tell you how much time you actually
spent asleep. The sleep detection is based on recording the movements of your
non-dominant hand with a digital 3D acceleration sensor.
Tracking your sleep gives you an insight into your sleep patterns, allowing
you to see where to make improvements or changes. Comparing your night to
night averages and assessing your patterns can help you spot what you’re doing
during the day that can affect your sleep. Weekly summaries in your Polar Flow
account help you evaluate how regular your sleep-wake pattern is.
What Polar Sleep PlusTM Measures Key Components of Sleep Tracking
· Sleep time – Sleep time tells you the total duration between when you fell
asleep and when you woke up. Your Polar device observes your body movements
and can detect when you fall asleep and wake up. It also detects interruptions
to your sleep during the entire Sleep time.
· Actual sleep – Actual sleep tells the time spent asleep between the time you
fell asleep and when you woke up. More specifically, it is your sleep time
minus the interruptions. Only the time you actually spend asleep is included
in actual sleep. Actual sleep can be presented as both percentage [%] and
duration [h:min].
· Interruptions – During a normal night’s sleep there are numerous short and
long interruptions when you actually awaken from your sleep. Whether you
remember these interruptions or not depends on their duration. The shorter
ones we don’t usually remember. The longer ones, for instance when one might
get up for a sip of water, we can remember.
33
· Sleep continuity – Sleep continuity describes how continuous your sleep was.
The continuity of your sleep is assessed on a scale of 1-5, where 5 reflects
very continuous sleep. The lower the value the more fragmented your sleep was.
A good night’s sleep consists of long uninterrupted sleep segments and does
not contain interruptions at frequent intervals.
· Self-evaluation – In addition to showing objective sleep metrics the Flow
service encourages you to self-evaluate your sleep daily. You can rate how
well you’ve slept last night with a five-step scale: very poorly – poorly okay
– well – very well. By answering this question, you get a longer version of
textual feedback about your sleep duration and quality.
ACTIVITY DATA IN FLOW APP AND FLOW WEB SERVICE
With the Flow app you can follow and analyze your activity data on the go and
have your data synced wirelessly from your A370 to the Flow web service. The
Flow web service gives you the most detailed insight into your activity
information.
GPS FROM MOBILE
You can track the routes, speed and distance of your outdoor training sessions
with A370, using your mobile device’s GPS. You need Polar Flow mobile app
installed in your mobile, paired with your A370 and give it permission to use
your phone’s location.
When you start your outdoor training session under Training, the GPS icon with
static circle will show you when the location is fixed and you can start
tracking your training session.
You need to keep your mobile device with you during the training session.
SMART NOTIFICATIONS (IOS)

POLAR SMART COACHING FEATURES
Whether it’s assessing your day-to-day fitness levels, creating individual
training plans, working out at the right intensity or receiving instant
feedback, Polar Smart Coaching offers a choice of unique, easy-to-use
features, personalized to your needs and designed for maximum enjoyment and
motivation when training.
A370 includes the following Polar Smart Coaching features:
l Activity Guide l Activity Benefit l Continuous Heart Rate l Heart Rate Based
Training l Running Program l Sleep Plus l Smart Calories l Sport Profiles l
Training Benefit
40
ACTIVITY GUIDE
The Activity Guide feature shows how active you’ve been during the day, and
tells you how much you need to still do to reach the recommendations for
physical activity per day. You can check how you’re doing in reaching your
activity goal for the day either from your A370, from the Polar Flow mobile
app or from the Polar Flow web service.
Note that your training session information is not included in the daily
activity data. In other words, the steps, the distance, the active time and
the calories as well as the overall progress towards reaching your daily
activity goal that are shown under the My day menu on your fitness tracker,
and under Activity in the Polar Flow mobile app and web service, represent all
the other activity you perform during the day, in addition to any recorded
training session. ACTIVITY GUIDE ON THE A370 Some of the watch faces on your
A370 show your progress towards your daily activity goal. Under My day menu
item you can see Activity card that shows your Activity for the day in more
detail. Here you can see the percentage of how much of your day’s activity
goal you’ve reached. The same is visualized also with an activity bar. Tap the
bar to see an example how to reach your goal for the day. ‘Up’ means low
intensity, ‘walking’ means medium intensity, and ‘jogging’ means high
intensity activities. With practical guidance like ’50 min walking’ or ’20 min
jogging´, you can choose how to reach your goal. You’ll find more examples for
low, medium and high intensity activities at the Polar Flow web service and
Polar Flow app. For more information, see 24/7 Activity Tracking.
ACTIVITY BENEFIT
Activity benefit gives you feedback on the health benefits that being active
has given you, and also on what kind of unwanted effects sitting for too long
has caused for your health. The feedback is based on international guidelines
and research on the health effects of physical activity and sitting behavior.
The core idea is: the more active you are, the more benefits you get! Both
Flow app and Flow web service show the activity benefit of your daily
activity. You can view the activity benefit on daily, weekly and monthly
basis. In the Flow web service, you can also view the detailed information on
health benefits.
41
For more information, see 24/7 Activity Tracking.
CONTINUOUS HEART RATE
Continuous Heart Rate feature measures your heart rate around the clock. It
enables more accurate measurement of daily calorie consumption and your
overall activity because also physical activities with very little wrist
movement, such as cycling, can now be tracked.
The Continuous HR feature is automatically on in your A370. You can toggle
between turning the Continuous
HR feature on and off on your A370 under Settings by tapping the
icon. Polar’s Continuous HR feature
measures your heart rate in an intelligent, adaptable and optimized manner. Still, keeping the Continuous HR
feature on in your Polar device will drain the battery quicker.
Under My day you’ll be able to follow what will be the highest and lowest heart rate readings of your day and you can check what your lowest heart rate reading was during the previous night. You can follow the readings in more detail and in longer periods in Polar Flow, either in web or in the mobile app.
Polar’s Continuous Heart Rate tracking starts every few minutes or based on your wrist movements.
The timed measurement checks your heart rate every few minutes and if your heart rate is elevated during the check, the Continuous HR feature starts to track your heart rate. Continuous HR tracking can also start based on your wrist movements, for example, when you’re walking with a fast enough pace for at least one minute.
The continuous tracking of your heart rate stops automatically when your activity level drops low enough. When your Polar device detects that you’ve been sitting for a long time, the Continuous HR tracking starts in order to find the lowest heart rate reading of your day.
42
SMART CALORIES
The most accurate calorie counter on the market calculates the number of calories burned, with continuous HR tracking it is even more accurate. The energy expenditure calculation is based on:
l Body weight, height, age, gender l Individual maximum heart rate (HRmax) l
Heart rate during training and during continuous HR tracking l Activity
measurement outside of training sessions and when you train without heart rate
l Individual maximal oxygen uptake (VO2max)
VO2max tells about your aerobic fitness. You can find out your estimated
VO2max with the Polar Fitness Test. Available only with Polar H7 and H10 heart
rate sensors.
HEART RATE ZONES
Polar heart rate zones introduce a new level of effectiveness in heart rate- based training. Training is divided into five heart rate zones based on percentages of maximum heart rate. With heart rate zones, you can easily select and monitor training intensities.
Target zone MAXIMUM

Recommended for: For recovery and cool-down, throughout training season.
- HRmax = Maximum heart rate (220-age).
** Heart rate zones (in beats per minute) for a 30-year-old person, whose maximum heart rate is 190 bpm (22030).
Training in heart rate zone 1 is done at a very low intensity. The main training principle is that performance improves when recovering after, and not only during training. Accelerate the recovery process with very light intensity training.
Training in heart rate zone 2 is for endurance training, an essential part of any training program. Training sessions in this zone are easy and aerobic. Long-duration training in this light zone results in effective energy expenditure. Progress will require persistence.
44
Aerobic power is enhanced in heart rate zone 3. The training intensity is
higher than in sport zones 1 and 2, but still mainly aerobic. Training in
sport zone 3 may, for example, consist of intervals followed by recovery.
Training in this zone is especially effective for improving the efficiency of
blood circulation in the heart and skeletal muscles.
If your goal is to compete at top potential, you will have to train in heart
rate zones 4 and 5. In these zones, you exercise anaerobically in intervals of
up to 10 minutes. The shorter the interval, the higher the intensity.
Sufficient recovery between intervals is very important. The training pattern
in zones 4 and 5 is designed to produce peak performance.
The Polar target heart rate zones can be personalized by using a laboratory
measured HRmax value, or by taking a field test to measure the value yourself.
You can edit the heart rate zone limits separately on each sport profile you
have on your Polar account in the Polar Flow web service.
When training in a target heart rate zone, try to make use of the entire zone.
The mid-zone is a good target, but keeping your heart rate at that exact level
all the time is not necessary. Heart rate gradually adjusts to training
intensity. For instance, when crossing from heart rate target zone 1 to 3, the
circulatory system and heart rate will adjust in 3-5 minutes.
Heart rate responds to training intensity depending on factors such as fitness
and recovery levels, as well as environmental factors. It is important to look
out for subjective feelings of fatigue, and to adjust your training program
accordingly.
POLAR RUNNING PROGRAM
Polar Running program is a personalized program based on your fitness level,
designed to make sure that you train right and avoid overreaching. It’s
intelligent and adapts based on your development, and lets you know when it
might be a good idea to cut back a little and when to step it up a notch. Each
program is tailored for your event, taking your personal attributes, training
background and preparation time into account. The program is free, and
available in the Polar Flow web service at flow.polar.com.
Programs are available for 5k, 10k, half marathon and marathon events. Each
program has three phases: Base building, Build-up and Tapering. These phases
are designed to gradually develop your performance, and make sure you’re ready
on race day. Running training sessions are divided into five types: easy jog,
medium run, long run, tempo run and interval. All sessions include warm-up,
work, and cool-down phases for optimal results. In addition, you can choose to
do strength, core, and mobility exercises to support your development. Each
training week consists of two to five running sessions, and the total running
training session duration per week varies from one to seven hours depending on
your fitness level. The minimum duration for a program is 9 weeks, and the
maximum is 20 months.

Weekly award
If you’re training for a running event using the Polar Running program, your
A370 will award you for sticking to your training plan.
You’ll receive award stars to your A370 as feedback based on how well you’ve
followed the program each week. You’ll get the award as the week changes, that
is either on Monday, Saturday or Sunday, depending on the First day of week
setting you’ve chosen in your Polar account’s General settings.
The number of stars you get depends on how well you’ve met your targets. Your
actual time spent on the different heart rate zones during training is
compared to the training target’s planned time for each heart rate zone. Check
the info below to see what is needed for each number of stars, or why you
didn’t get any stars some week.
l 1 Star: On average, you’ve met 75% of your target on each heart rate zone. l
2 Stars: On average, you’ve met 90 % of your target on each heart rate zone. l
3 Stars: On average, you’ve met 100 % of your target on each heart rate zone.
l No stars: You’ve trained too much (more than 200%) on moderate zones (1 -3).
l No stars: You’ve trained too much (more than 150%) on high intensity
training zones (4 and 5).
Remember to start your training sessions using the training targets, so your
training session results will be compared to the targets.
46
POLAR SLEEP PLUSTM
The A370 tracks your sleep if you wear it at night. It detects when you fall
asleep and when you wake up and collects the data for deeper analysis in the
Polar Flow app and web service. The A370 observes your hand movement during
the night to track all interruptions over the entire sleep span, and tells you
how much time you actually spent asleep.
Sleep data on your A370
You can check your sleep data from My day sleep card. Tap it to get detailed
information. l Sleep time tells you the total duration between when you fell
asleep and when you woke up. l Actual sleep tells the time spent asleep
between the time you fell asleep and when you woke up. More specifically, it
is your sleep time minus the interruptions. Only the time you actually spend
asleep is included in actual sleep. l Sleep continuity is a rating of how
continuous your sleep time was. l The times you fell asleep and woke up. l
Feedback based on your sleep data, preferred sleep time and how you rated your
sleep. l Your given sleep rating with a smiley icon.
Sleep data in the Flow app and web service
Your sleep data is shown in the Flow app and web service after your A370 is
synced. The Flow app and web service show your sleep data in one night and
week views. In the Flow web service, you can view your sleep under the Sleep
tab in your Diary. You can also include your sleep data to Activity reports
under the Progress tab.
In the Polar Flow app and web service, you can set Your preferred sleep time
to define how long you aim to sleep every night. You can also rate your sleep.
You will receive feedback on how you slept based on your sleep data, your
preferred sleep time and your sleep rating.
By following your sleep patterns you can see if they’re affected by any
changes in your daily life and find the right balance between rest, daily
activity and training.
POLAR SPORT PROFILES
We have created seven default sport profiles to your A370. In the Flow web
service you can add new sport profiles and sync them to your A370, and this
way create a list of all your favorite sports. You can also define some
specific settings for each sport profile. For example, set vibration feedback
off in in the yoga sport profile. For more information, see Sport Profiles in
Flow Web Service.
47
Using sport profiles makes it possible for you to keep up with what you’ve done and see the progress you’ve made in different sports. You can do this in the Flow web service.
TRAINING BENEFIT
Training Benefit gives you textual feedback on your performance for each training session helping you better understand the effectiveness of your training. You can see the feedback in Flow app and Flow web service. To get the feedback, you need to have trained at least a total of 10 minutes in the heart rate zones.

IMPORTANT INFORMATION
TAKING CARE OF YOUR A370
Like any electronic device, Polar A370 should be treated with care. The
suggestions below will help you fulfill guarantee obligations and enjoy this
product for many years to come. The USB cable must be connected carefully to
avoid damaging the device’s USB port. Don’t charge the device when its USB
port is wet. Let the USB port dry up by leaving the port cover open for a
while before charging. This way you’ll ensure smooth charging and syncing.
Keep your training device clean. l We recommend that you wash the device and
the silicone wristband after each training session under running water with a
mild soap and water solution. Please remove the device from the wristband and
wash them separately. Wipe them dry with a soft towel. It is essential that
you wash the device and the wristband if you wear them in a swimming pool
where
chlorine is used for keeping the pool clean. l If you don’t wear the device
24/7, wipe off any moisture before storing it. Don’t store in non-breathable
material or in a damp environment, e.g. plastic bag or damp gym bag. l Wipe it
dry with a soft towel when needed. Use a damp paper towel to wipe dirt from
the training device. To maintain the water resistance, do not wash the
training device with a pressure washer. Never use alcohol or any abrasive
material such as steel wool or cleaning chemicals.
58
l When you connect your A370 to a computer or a charger, check that there is
no moisture, hair, dust or dirt on the A370’s USB connector. Gently wipe off
any dirt or moisture. Don’t use any sharp tools for cleaning to avoid
scratching.
Operating temperatures are -10 °C to +50 °C / +14 °F to +122 °F.
STORING
Keep your training device in a cool and dry place. Do not keep them in a damp
environment, in non-breathable material (a plastic bag or a sports bag) nor
with conductive material (a wet towel). Do not expose the training device to
direct sunlight for extended periods, such as by leaving it in a car or
mounted on the bike mount.
It is recommended to store the training device partially or fully charged. The
battery slowly loses its charge when it is stored. If you are going to store
the training device for several months, it is recommended to recharge it after
a few months. This will prolong the battery lifetime.
Dry and store the strap and the connector separately to maximize the heart
rate sensor battery lifetime. Keep the heart rate sensor in a cool and dry
place. To prevent snap oxidation, do not store the heart rate sensor wet in
non-breathing material, such as a sports bag. Do not expose the heart rate
sensor to direct sunlight for extended periods.
SERVICE
During the two-year guarantee/warranty period we recommend that you have
service done by an authorized Polar Service Center only. The warranty does not
cover damage or consequential damage caused by service not authorized by Polar
Electro. For further information, see Limited International Polar Guarantee.
For contact information and all Polar Service Center addresses, visit
support.polar.com and country-specific websites.
BATTERIES
At the end of the working life of the product Polar encourages you to minimize
possible effects of waste on the environment and human health by following
local waste disposal regulations and, where possible, utilizing separate
collection of electronic devices. Do not dispose of this product as unsorted
municipal waste.
CHARGING A370 BATTERY
The A370 has an internal, rechargeable battery. Rechargeable batteries have a
limited number of charge cycles. You can charge and discharge the battery over
300 times before a notable decrease in its capacity. The number of charge
cycles also varies according to use and operating conditions.
Do not charge the battery in temperatures under 0°C or over +40°C or when the
USB port is wet.
You can charge the battery via a wall outlet. When charging via a wall outlet,
use a USB power adapter (not included in the product set). If you use a USB
power adapter, make sure that the adapter is marked with
59
“output 5Vdc” and that it provides a minimum of 500mA. Only use an adequately
safety approved USB power adapter (marked with “LPS”, “Limited Power Supply”,
“UL listed” or “CE”).
Do not charge Polar products with a 9 volt charger. Using a 9 volt charger can
damage your Polar product.
To charge with your computer just plug your A370 to your computer and at the
same time you can have it synced it with FlowSync.
1. Push down the top part (A) of the USB cover inside the bracelet to access
the micro USB port and plug in the supplied USB cable (B).
60
2. Plug the other end of the cable into your computer’s USB port. Check that
the USB port is dry before connecting it to the computer. If the battery is
completely empty, it takes a couple of minutes for the charging to start.
3. After syncing, green battery icon animation begins to fill up on the
display. 4. When the green battery icon is full, the A370 is fully charged.
Don’t leave the battery fully discharged for a long period of time or keep it
fully charged all the time, because it may affect the battery life time.
BATTERY OPERATING TIME The battery operating time is up to 4 days with 24/7
activity tracking, continuous HR tracking and 1h/day training without Smart
Notifications on. The operating time depends on many factors, such as the
temperature of the environment in which you use your A370, the features you
use, how much the display is on and battery aging. The operating time is
significantly reduced in temperatures well below freezing. Wearing the A370
under your overcoat helps to keep it warmer and to increase the operating
time. LOW BATTERY NOTIFICATIONS Battery low. Charge The battery charge is low.
It is recommended to charge A370.
61
Charge before training.
The charge is too low for recording a training session. A new training session
cannot be started before charging A370.
When the display doesn’t wake up from a wrist gesture or a press of the
button, the battery is empty and A370 has gone to sleep mode. Charge your
A370. If the battery is totally drained, it may take a while for the charging
animation to appear on the display.
PRECAUTIONS
The Polar A370 is designed to measure heart rate and tell your activity. No
other use is intended or implied.
The training device should not be used for obtaining environmental
measurements that require professional or industrial precision.
The Polar A370 is not a medical device for measuring your heart rate.
We recommend that once in a while you wash the device and the wrist strap to
avoid any skin problems from a dirty bracelet.
INTERFERENCE
Electromagnetic Interference and Training Equipment
Disturbance may occur near electrical devices. Also WLAN base stations may
cause interference when training with the training device. To avoid erratic
reading or misbehavior, move away from possible sources of disturbance.
Training equipment with electronic or electrical components such as LED
displays, motors and electrical brakes may cause interfering stray signals.
If the training device still does not work with the training equipment, it may
be electrically too noisy for wireless heart rate measurement. For further
information, support.polar.com.
MINIMIZING RISKS WHEN TRAINING
Training may include some risk. Before beginning a regular training program,
it is recommended that you answer the following questions concerning your
health status. If you answer yes to any of these questions, we recommend that
you consult a doctor before starting any training program.
l Have you been physically inactive for the past 5 years? l Do you have high
blood pressure or high blood cholesterol? l Are you taking any blood pressure
or heart medication?
62
l Do you have a history of breathing problems?
l Do you have symptoms of any disease?
l Are you recovering from a serious illness or medical treatment?
l Do you use a pacemaker or other implanted electronic device?
l Do you smoke?
l Are you pregnant?
Note that in addition to training intensity, medications for heart conditions,
blood pressure, psychological conditions, asthma, breathing, etc., as well as
some energy drinks, alcohol, and nicotine may also affect heart rate.
It is important to be sensitive to your body’s responses during training. If
you feel unexpected pain or excessive fatigue when training, it is recommended
that you stop the training or continue at a lighter intensity.
Note! If you are using a pacemaker, defibrillator or other implanted
electronic device, you can use Polar products. In theory interference to
pacemaker caused by Polar products should not be possible. In practice no
reports exist to suggest anyone ever having experienced interference. We
cannot however issue an official guarantee on our products’ suitability with
all pacemakers or other implanted devices, such as defibrillators, due to the
variety of devices available. If you have any doubts, or if you experience any
unusual sensations while using Polar products, please consult your physician
or contact the implanted electronic device manufacturer to determine safety in
your case.
If you are allergic to any substance that comes into contact with your skin or
if you suspect an allergic reaction due to using the product, check the listed
materials in Technical Specifications.
If you use perfume, suntan/sunscreen lotion or insect repellent on your skin, you must ensure that it does not come into contact with the training device or the heart rate sensor. Please avoid clothing with colors that might transfer onto the training device (especially training devices with light/bright colors) when worn together.

POLAR FLOW MOBILE APPLICATION COMPATIBILITY
Polar devices work with most modern smartphones. Here are the minimum
requirements: l iOS devices with iOS 11 or later l Android mobile devices with
Bluetooth 4.0 capability and Android 5 or later (check full phone
specification from your phone manufacturer)
There is plenty of variation between how different Android devices handle the
technologies used in our products and services, such as Bluetooth Low Energy
(BLE) and different standards and protocols. Because of this, compatibility
varies between phone manufacturers, and unfortunately Polar cannot guarantee
that all features can be used with all devices.
WATER RESISTANCE OF POLAR PRODUCTS
Most Polar products can be worn when swimming. They are not, however, diving
instruments. To maintain water resistance, do not press the buttons of the
device under water. Polar devices with wrist-based heart rate measurement are
suitable for swimming and bathing. They will collect your activity data from
your wrist movements also when swimming. In our tests, however, we found that
the wrist-based heart rate measurement doesn’t work optimally in water, so we
cannot recommend wristbased heart rate measurement for swimming. In the watch
industry, water resistance is generally indicated as meters, which means the
static water pressure of that depth. Polar uses this same indication system.
Water resistance of Polar products is tested according to International
Standard ISO 22810 or IEC60529. Every Polar device that has water resistance
indication is tested before the delivery to stand water pressure. Polar
products are divided into four different categories according to their water
resistance. Check the back of your Polar product for the water resistance
category, and compare it to the chart below. Please note that these
definitions do not necessarily apply to products of other manufacturers. When
performing any underwater activity, the dynamic pressure generated by moving
in water is greater than the static pressure. This means that moving the
product under water subjects it to a greater pressure than if the product were
stationary.
