To find your target heart rate zone, you need
to know your maximum heart rate (HRmax).
To estimate your HRmax, use the following
formula:
HRmax = 220 – age
Your HRmax = 220 – ______ = ________
For a more accurate measurement, visit your
doctor for an exercise stress test.
Your target heart rate zone is a high and low
range which represents percentages of your
current HRmax.
When your heart beats at 50-60% of your
HRmax, you're in the light intensity zone.
This kind of exercise is easy (a walk,
for instance), but already delivers some
health benefits.
Push on to 60-70% of your HRmax and you're
in the light to moderate intensity zone.
This is good for improving fitness, building
endurance and recommended for weight loss.
At 70-85% of your HRmax, you've moved into
the moderate to heavy intensity zone. This is
harder work, but good for strengthening your
aerobic fitness.
Find out your target zones:
Light intensity:
upper limit 0.60 x your HRmax =
lower limit 0.50 x your HRmax =
Light to moderate intensity:
upper limit 0.70 x your HRmax =
lower limit 0.60 x your HRmax =
Moderate to heavy intensity:
upper limit0.85 x your HRmax =
lower limit 0.70 x your HRmax =
We recommend having all service done by an authorized
Polar Service Center. Warranty does not cover damage
or consequential damage caused by service not
authorized by Polar Electro Inc. Water resistance
cannot be guaranteed after an unauthorized service.
However, if you wish to use a local watch shop or battery
replacement center or to change the battery yourself,
please follow these instructions.
You need the following equipment:
• Battery type: Panasonic CR 2025, 3V Li
• Piece of dust-free pad
• Small Philips or standard screwdriver
• Plastic tweezers (recommended)
1. Put the wrist receiver on a clean, dust-free pad
on an even table surface and open the back cover
by removing the screws counterclockwise.
Do not turn the receiver upside down since the module
may fall off.
2. Push the spring gently. Lift the spring gently upwards
and release the other end of the spring, too.
3. Take the old battery off and put a new battery in the
battery housing + side up, using plastic tweezers.
Do not use metal tweezers because they may
shortcircuit the battery. Note also that bare fingers
cause grease and contaminate the battery, which
weakens the contact.
4. Assemble the plate back in reverse order, placing the
rotating joint properly in the slot. Press the spring
gently so that it locks the battery in its proper position.
5. Reset the receiver by pressing the reset spring against
the round golden pad for 1 second.
6. Check the display. All digits are displayed.
7. Make sure that the sealing ring is not damaged and
it is in its groove all the way around the housing.
8. Put the back cover in its place. The Polar logo
on the outside of the back cover is in the upright
position with respect to the buckle side of
the wrist strap.
9. Tighten the screws from opposite corners. Do not
force the screws or damage the existing threads.
Check that the sealing ring has stayed in its groove
and it is not showing from the joint.
10.Test the functioning. Mount the transmitter and
wet its electrodes. Start heart rate measurement
by pressing the button. In case the heart rate
measurement does not start or all segments
do not appear normally, reopen the case and
go back to the point 5, reset the receiver.

Exercise may include some risk, especially for those who
have been sedentary. To minimize possible risks consider
the following advice:
Before beginning a regular exercise program consult
your doctor
• if you are over 40 years of age and have not been
following a regular exercise program during
the past 5 years
• if you smoke
• if you have high blood pressure
• if you have high blood cholesterol
• if you have any signs or symptoms of any disease
• if you are recovering from a serious illness or
a medical treatment e.g. surgery
• if you use a pacemaker or another implanted
electronic device.
Note that in addition to exercise intensity, heart, circulation
(particularly high blood pressure), asthma and other breathing
medications as well as some energy drinks, alcohol and nicotine,
can affect the heart rate.
It is important to be sensitive to your body’s reactions during
exercise. If you feel unexpected pain or excessive fatigue when
exercising, 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.
