Heart Rate Monitor
Parts and Their
Functions
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.
The wrist receiver
displays your heart rate
and other data during
exercise. Enter your
personal settings into the
receiver and analyze the
exercise files after you’re
done.

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.
Easy Start
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 Watch Settings)
and personal user settings (see section User information
settings).
3. Polar 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
using 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™.
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
3 feet/ 1 meter of your transmitter.
3. Check that you are not near people that have
heart rate monitors, high voltage power lines,
televisions, mobile phones or other sources of
electromagnetic disturbance.
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
conductivity and functioning of the transmitter. Sweat and moisture can
keep the electrodes wet and the transmitter activated, which shortens
battery life.
Modes and Their Functions
Your Polar heart rate monitor 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 that
shows the date and the day of the week, as well as contains an alarm
function. You can also change between two different countries’ time
zones. In addition, the following functions can be uploaded from a
computer and utilized:
• 7 alarm sound reminders
• your personal logo, user number or user name
2. EXERCISE
In the Exercise mode, you measure your heart rate and exercise
information is recorded in the File mode. You can preset up to five
exercise sets for your personal needs. You can also name these exercises
on your receiver. When you start exercising, just select one of the saved
sets. Or, you can select BasicUse (heart rate measurement without
heart rate limits, timers or other exercise guiding functions).
A. During BasicUse, you can save 99 split and lap times with current,
maximum and average heart rates for each lap. You can configure the
display to show information on the following:
• your current heart rate, average heart rate or a reading of your
maximum heart rate in percentages
• the current exercise time (stopwatch)
• time of day
• current lap and split time as well as the lap number
• calorie count for your exercise session
B. Freely programmable BasicSet will automatically guide you
through your exercise session with the help of the following functions:
• three adjustable target heart rate limits
• three adjustable, alternating timers
• time-based or heart-rate-based recovery calculation
C. Freely programmable Interval Trainer will automatically guide
you through your interval training session with the help of the
following, preset exercise phases:
• warm-up with a target heart rate zone and a countdown timer
• up to 30 intervals with a target heart rate zone. After each
interval you have a recovery calculation option.
• cool-down with a target zone and a countdown timer
3. FILE
Your receiver stores exercise information in 99 exercise files:
• the start date and time of the exercise
• total exercise time
• the average and maximum heart rate readings for the exercise session
• the recovery value (only BasicSet)
• your heart rate limits used during the exercise
• your time spent in, above and below your target zones during exercise
• OwnCal calorie expenditure
• your cumulative calorie expenditure
• your cumulative exercise time
• your interval training information: warm-up, interval and cool-down phases
• your lap information: best lap time; lap and split times; and current,
average and maximum heart rate for each lap
• your heart rate samples recorded in the set recording rate
In addition to exercise file, your cumulative calories and exercise time are
updated to your records file.
4. OPTIONS
In the Options mode, you can enter the following settings:
Exercise Settings: You can select BasicUse with no settings or 5 freely
programmable BasicSets or Interval Training Sets
Memory Settings: Set the recording rate of your heart rate of 5
seconds, 15 seconds or 1 minute
Function settings: OwnCal calorie counter on/off, fitness test on/off,
predicted maximum heart rate on/off
User-specific Information: weight, height, date of birth, gender,
activity level, maximum heart rate and maximal oxygen uptake
Monitor Settings: activity/button sound on/off, measurement units,
Help on/off
Watch Settings: alarm, time of day, date, reminders on/off
5. FITNESS TEST
In this mode you can:
• perform the Polar Fitness Test
• recall your latest test results; OwnIndex and HR
-p values

analysis with Polar Precision Performance version 3 or later
B. HOW TO ENTER SETTINGS
This section describes how to manually enter
