Polar heart rate monitor models S720i and S710i offer you the same features.
The difference between these products is in their appearance: Polar S720i case
is stainless steal whereas Polar S710i case is plastic.
The features of this heart rate monitor provides you with the various ways to
customise your exercise sessions so they meet your personal needs.
For example, use the Interval Trainer™ function to guide you through a complete
interval training session. Or, you can choose the functions that suit you best:
e.g. timers, recovery calculation and cycling information. After training, you
can review your exercise file and transfer it to your computer for analysis with
Polar Precision Performance™ software. Monitor your fitness level, and any
long-term changes in it, by performing the quick and easy Polar Fitness Test™.
Please read this manual carefully to familiarise yourself with the Polar heart rate
monitor. Here is where you can find the information you need to use and
maintain your equipment. The function road map on the front cover is a quick
guide to the versatile features of the Polar heart rate monitor; please tear it off.
Please refer to the glossary for special terms, display symbols and text
explanations. The alphabetical index will help you quickly find answers to
any questions that you might encounter while using your Polar heart rate
monitor.
Thank you for choosing Polar!

The elastic strap holds
the transmitter
comfortably, yet firmly,
in the correct position.
The transmitter detects
your heart rate and
transmits it to the wrist
receiver.

exercise. Enter your
personal settings into
the receiver

Useful tips
•Briefly pressing a button (approximately 1 second) will do different
things than pressing and holding the button for a longer period of
time (approximately 2 to 5 seconds). If your press the button for a
longer period of time, you can use shortcuts.
•The buttons are slightly stiffer than those of an ordinary watch to
prevent them from being pressed accidentally.
•You can always return to the Time of day display from the Options
setting or File recalling loops by pressing and holding the stop button.
•See the glossary for display symbols and text interpretation.
Up Moves to the following
mode. Increases the

How to prepare the wrist receiver
1. Since the display is blank when the receiver leaves the
factory, you have to activate the wrist receiver by pressing
the OK button twice, after which the Time of day display
appears. This is a one-off procedure; once you have turned
on your receiver you can not turn it off anymore.
2. You may start measuring your heart rate right away
using the default settings. However, the following
settings are ones that it would be useful to change as
soon as possible: Time of day (see section Setting the
watch) and personal user settings (see section User
information settings).
3. Your heart rate monitor has various functions that you can
use according to your personal training needs. For more
information, see section Modes and their functions. You
can either manually enter the settings by pressing the
receiver buttons or you can define your settings Polar
Precision Performance software, after which the data
should be transferred from your computer to the wrist
receiver.
4. Wear the wrist receiver as you would wear an ordinary
watch. If you go biking, we recommend attaching the
wrist receiver to a Polar Bike Mount™.
Easy start

A 9
Installing the Polar Bike Mount
Use cable ties to secure the bike mount
snugly on the rubber pad.
Attach the receiver by securing the wrist
strap.
Installing the Polar Speed Sensor™
The Polar Speed Sensor measures speed
and distance when cycling.
1. Check the front side of the front
fork to find a suitable place for the
speed sensor. The sensor should be
attached less than 50 cm/ 1’8" from the
mounted wrist receiver. The smaller the
distance the better. Clean and dry the
area underneath the rubber pad before
you attach it to the front fork.
2. Place the sensor in the position as in
illustration 2. Then adjust the sensor
towards the wheel as much as possible.
3. Pass the cable ties through the
sensor holes and loosely adjust the
ties. Do not tighten fully yet.
If the cable ties are too short for
your bicycle, put two of them
together to make them longer.

4. There are two spoke magnet options.
You only need to install one of them.
Check which of the magnets fits the spoke
of your bike best. One (A) is installed by
rotating it around the spoke before putting
the metal cover on, another (B) by
tightening the screw. The magnet must be
facing the speed sensor.
5. Fine-tune the positioning of both the
magnet and the sensor so that the magnet
passes the sensor closely but does not
touch it. The maximum distance between
the speed sensor and the spoke magnet
should be 5 mm/ 0.2". Once positioned
correctly, tighten the cable ties securely
and cut off any excess cable tie ends.
Your safety is important to us. While riding
your bike, please keep your eyes on the
road to prevent possible accidents and
injury. Check that you can turn the handle
bar normally and cable wires for brakes or
gearing do not catch on the sensor. Check
also that the sensor does not disturb
pedalling or the use of brakes or gearing.

How to put the transmitter on
1. Attach the transmitter to the elastic strap.
2. Adjust the strap length to fit snugly and
comfortably. Secure the strap around your
chest, just below the chest muscles, and
buckle it.
3. Lift the transmitter off your chest and
moisten the grooved electrode areas
on the back.
4. Check that the wet electrode areas are firmly
against your skin and the Polar logo is in a
central, upright position.
How to start measuring your heart rate
1. Begin with the display that shows
the time of day.
2. Keep the wrist receiver within
1 metre/ 3 feet of your transmitter.
3. Check that you are not near other people
that have heart rate monitors, high voltage
power lines, televisions, mobile phones or
other sources of electromagnetic disturbance.

A 12
4. Press the OK button to start measuring your heart rate. A heart symbol
will start flashing and your heart rate (beats per minute) will appear in
a maximum of 15 seconds.
5. Press OK again. The stopwatch starts running and you can start
exercising. The exercise data will only be stored in a file if you have
turned the stopwatch on.
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
recorded.
2. Press the stop button again. The heart rate measuring stops.
The receiver shows the Time of day display again.
After exercising
1. Carefully wash the transmitter with a mild soap and water solution.
2. Rinse it with pure water.
3. Dry the transmitter carefully with a soft towel.
4. Store the transmitter in a clean and dry place. Dirt impairs the elasticity
and functioning of the transmitter. Sweat and moisture can keep the
electrodes wet and the transmitter activated, which shortens battery life.

Your receiver has six main modes: Time of day, Exercise, File, Options,
Fitness test and Connection.
1. TIME OF DAY
You can use your Polar heart rate monitor as an ordinary watch with
date, weekday indicator and alarm function.
