2. BEFORE TRAINING
Polar Fitness Test
To train right and to monitor your progress, it is
important to know your current fitness level. The
Polar Fitness Test™ is an easy and quick way to
measure your cardiovascular fitness and aerobic
capacity. The test is performed at rest.
The test result is a value called Polar OwnIndex®.
OwnIndex is comparable to maximum oxygen
uptake (VO
capacity measure. For more information, see
Interpret Your Fitness Test Results.
The OwnIndex value affects the accuracy of calorie
calculation during training.
8 Before Training
), a commonly used aerobic
2max
The test is developed for healthy adults. To make
sure the test results are reliable:
• avoid distractions. The more relaxed you are and
the more peaceful the testing environment is,
the more accurate the test result will be (for
instance, no television, telephone or talking).
• avoid heavy physical exertion, alcohol and
unprescribed pharmacological stimulants on the
test day and the day before.
• avoid eating a heavy meal or smoking 2-3 hours
prior to the test.
• always perform the test in similar conditions and
at the same time during the day.
• enter accurate user information.
ENGLISH
Perform Polar Fitness Test
1. Wear the transmitter, lie down and relax for 1-3
minutes.
2. In Time view, select UP/DOWN > Test > Start.
The fitness test begins as soon as the RS300X
locates your heart rate. So, make sure you are
relaxed and ready to take the test when you
press Start.
3. Approximately 5 minutes later, a beep will
indicate the end of the test, and the test result

OwnZone Limits
Your training computer can determine your
individual aerobic heart rate zone automatically.
This feature is called Polar OwnZone®(OZ).
Starting every training session with the OwnZone
guarantees safe and effective heart rate zones for
your daily condition. It is recommended you
determine your OwnZone when you change
training environment or sport/user information, if
you have not yet fully recovered from a previous
training session, or are training for the first time
after a break of one week or more.
OwnZone limits are determined in 1-5 minutes
during a warm-up period by walking, jogging, or
doing some other sport. Start slowly, keeping your
heart rate below 100 bpm / 50 % HR
each minute, increase your speed gradually about
10 bpm / 5% HR

Wear the Transmitter
Before recording a training session, wear the transmitter.
1. Wet the electrode areas of the strap well under running water.
2. Attach the connector to the strap. Adjust the strap length to fit
it tightly but comfortably.
3. Tie the strap around your chest, just below the chest muscles,
and attach the hook to the other end of the strap.
4. Check that the wet electrode areas are firmly against your skin
and that the Polar logo of the connector is in a central and
upright position.
Detach the connector from the strap after every use, to maximize
the transmitter battery lifetime. Sweat and moisture may keep
the electrodes wet and the transmitter activated. This will reduce
the transmitter battery life.

6. IMPORTANT INFORMATION
ENGLISH
Caring for Your Polar RS300X
Like any electronic device, the Polar training computer
should be treated with care. The suggestions below will
help you fulfill guarantee obligations and enjoy this
product for many years to come.
Detach the transmitter connector from the strap and rinse
the strap under running water after every use. Dry the
connector with a soft towel. Never use alcohol or any
abrasive material (steel wool or cleaning chemicals).
Wash the strap regularly in a washing machine at
40ºC/104ºF or at least after every fifth use. This ensures
reliable measurement and maximizes the life span of the
transmitter. Use a washing pouch. Do not soak, spin-dry,
iron, dry clean or bleach the strap. Do not use detergent
with bleach or fabric softener. Never put the transmitter
connector in the washing machine or drier!
Dry and store the strap and the transmitter connector
separately to maximize the transmitter battery lifetime.
Wash the strap in a washing machine before long-term
storage and always after use in pool water with high
chlorine content.
Keep your training computer and transmitter 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). The training
computer and transmitter are water resistant, and can be
used in water activities. Other compatible sensors are
water resistant, and can be used in rainy weather. Do not
expose the training computer to direct sunlight for
extended periods, such as by leaving it in a car or
mounted on the bike mount.
Keep your training computer clean. To maintain the water
resistance, do not wash the training computer with a
pressure washer. Clean the training computer with a mild
soap and water solution and rinse it with clean water. Do
not immerse it in water. Dry it carefully with a soft towel.
Never use alcohol or any abrasive material such as steel
wool or cleaning chemicals.
Avoid hard hits to the training computer, as these may
damage the sensor units.

Changing Batteries
Training Computer
We recommend that you have the training computer
battery replaced by an authorized Polar Service Center.
They test your Polar training computer for water resistance
after battery replacement.
The low battery indicator is displayed when 10–15% of
•
the battery capacity is left.
Excessive use of the backlight drains the battery more
•
rapidly.
In cold conditions, the low battery indicator may appear,
•
but will disappear when the temperature rises.
The backlight and sound are automatically turned off
•
when the low battery indicator is displayed. Any alarms
set prior to the appearance of the low battery indicator
will remain active.
Transmitter Connector
The WearLink+ transmitter has a user changeable battery.
To change the battery yourself, please follow the
instructions carefully.
When changing the battery, make sure the sealing ring is
not damaged, in which case you should replace it with a
new one. You can purchase the sealing ring/battery kits at
well-equipped Polar retailers and authorized Polar
Services. In the USA and Canada, the additional sealing
rings are available at authorized Polar Service Centers. In
USA the sealing ring/battery kits are also available at
www.shoppolar.com.
Keep the batteries away from children. If swallowed,
contact a doctor immediately.
Batteries should be properly disposed of according to local
regulations.
When handling a new, fully charged battery, avoid
clasp-like contact, i.e. simultaneous from both sides, with
metal or electrically conducting tools, like tweezers. This
may short-circuit the battery causing it to discharge more
rapidly. Typically, short circuiting does not damage the
battery, but it may decrease the capacity and lifetime of
the battery.

Precautions
The Polar training computer shows your performance
indicators. It indicates the level of physiological strain and
intensity during your training session. No other use is
intended or implied.
Minimizing Risks When Training
Training may include some risk. Before beginning a
regular training program, answer the following questions
concerning your health status. If you answer yes to any of
these questions, consult a physician before starting any
training program.
• Have you been physically inactive for the past five years?
• Do you have high blood pressure or 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 other implanted electronic
device?
• Do you smoke?
• Are you pregnant?
In addition to exercise 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 exercise. If you feel unexpected pain or excessive
fatigue when exercising, it is recommended that you stop
the exercise or continue at a lighter intensity.
Notice to individuals with pacemakers, defibrillators or
other implanted electronic devices. Individuals who have a
pacemaker use the Polar training computer at their own
risk. Before starting use, we always recommend a maximal
exercise stress test under a doctor’s supervision. The test
is to ensure the safety and reliability of the simultaneous
use of the pacemaker and the Polar training computer.
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. To avoid any skin
reaction to the transmitter, wear it over a shirt, but
moisten the shirt well under the electrodes to ensure
flawless operation.
The combined impact of moisture and intense abrasion may
cause a black color to come off the transmitter’s surface,
possibly staining light-colored clothes. If you use perfume or
insect repellent on your skin, you must ensure that it does not
come into contact with the training computer or the transmitter.
Important Information 39
ENGLISH
Training equipment with electronic components may cause interfering stray signals. To tackle these problems, try the
following:
1. Remove the transmitter from your chest and use the training equipment as you would normally.
2. Move the wrist unit around until you find an area in which it displays no stray reading or does not flash 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 your chest and keep the wrist unit in this interference-free area as much as possible.
If the RS300X still does not work, the piece of equipment may be electrically too noisy for wireless heart rate
measurement.
RS300X may be worn when swimming. To maintain water resistance, do not press buttons under water. For more
information, visit http://support.polar.fi. Water resistance of Polar products is tested according to International Standard
ISO 2281. Products are divided into three 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.
Marking on the case back Water resistant characteristics
Water resistant Protected against wash splashes, sweat, raindrops etc. Not
Water resistant 30 m/50 m Suitable for bathing and swimming.
Water resistant 100 m Suitable for swimming and snorkeling (without air tanks).
suitable for swimming.

ENGLISH
Troubleshooting
If you don't know where you are in the menu, press and
hold BACK until time is displayed.
If there are no reactions to any buttons or the training
computer displays unusual readings, reset the training
computer by pressing four buttons (UP, DOWN, BACK
and LIGHT) simultaneously for four seconds. All other
settings but time and date are saved.
If the heart rate reading becomes erratic, extremely high
or shows nil (00), make sure that there are no other heart
rate transmitters within 1 m/3 ft and that the transmitter
strap/the textile electrodes fit snugly and are wet, clean
and undamaged.
If the heart rate measurement does not work with the
sports apparel, try using the strap. If it works, the problem
is most probably in the apparel. Please contact the
apparel retailer/manufacturer.
Strong electromagnetic signals can cause erratic readings.
Electromagnetic 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 training
equipment, cellular phones, or at electric security gates.
To avoid erratic readings, move away from possible
sources of disturbance.
If the abnormal reading continues despite moving away
from the source of disturbance, slow down and check your
pulse manually. If you feel it corresponds to the high
reading on the display, you may be experiencing cardiac
arrhythmia. Most cases of arrhythmia are not serious, but
consult your physician nevertheless.
A cardiac event may have altered your ECG waveform. In
this case, consult your physician.
If heart rate measurement fails despite the actions
mentioned previously, the battery of your transmitter may
be empty.
