exercise.
2. Polar WearLink®31 Coded Transmitter: The transmitter sends the heart rate signal to the cycling
computer. The transmitter consists of a connector and a strap.
3. Polar Bike Mount™: Secure the bike mount to your bike and attach the cycling computer to it.
4. Polar Speed Sensor™: A wireless speed sensor measuring speed and distance during cycling.
5. Optional Cadence Sensor™: A wireless cadence sensor measuring the speed at which you turn the
cranks of your bicycle, expressed in revolutions per minute (rpm).
6. CD-ROM: Including Polar ProTrainer 5™ software and a complete User Manual to help you make
the most out of your cycling computer.
Polar CS400 User Manual 5
3. GETTING STARTED
Before activating your cycling computer, measure the wheel size of your bicycle.
Measuring Wheel Size
Wheel size settings are a prerequisite for correct cycling information. There are two ways of
determining the wheel size of your bike:
Method 1
Look for the diameter in inches or in ETRTO printed on the wheel. Match it to the wheel size in
millimeters in the right column of the chart.
ETRTO
25-559
23-571
35-559
37-622
47-559
20-622
52-559
23-622
25-622
28-622
32-622
42-622
47-622
Wheel size diameter (inches) Wheel size setting (mm)
26 x 1.0 1884
650 x 23C 1909
26 x 1.50 1947
700 x 35C 1958
26 x 1.95 2022
700 x 20C 2051
26 x 2.0 2054
700 x 23C 2070
700 x 25C 2080
700 x 28 2101
700 x 32C 2126
700 x 40C 2189
700 x 47C 2220
Wheel sizes on the chart are advisory as wheel size depends on the wheel type and air pressure.
Method 2
Measure the wheel manually for the most accurate result.
Use the valve to mark the point where the wheel touches the ground. Draw a line on the ground to
mark that point. Move your bike forward on a flat surface for one complete rotation. The tire should be
perpendicular to the ground. Draw another line on the ground at the valve to mark a full rotation.
Measure the distance between the two lines.
Subtract 4 mm to account for your weight on the bike to get your wheel circumference. Enter this
value in the cycling computer.
Basic Settings
Before using your cycling computer for the first time, customize the basic settings. Enter as accurate
data as possible to ensure correct feedback based on your performance.
Polar CS400 User Manual 6
To adjust the data, use UP, DOWN and accept with OK. The values scroll faster if you press and hold
UP or DOWN.
1. To activate your cycling computer, press OK twice. Once activated, it cannot be switched off!
2. Welcome to Polar Cycling World! is displayed. Press OK.
3. Language: Select English, Deutsch, Español, Français or Italiano. Press OK
4. Start with bike settings is displayed. Press OK.

6. Wheel: Enter the wheel size (mm) for each of your bicycles. For further information, see Measuring
Wheel Size.
7. Start with basic settings is displayed. Press OK and adjust the following data:
8. Time: Select 12h or 24h. With 12h, select AM or PM. Enter the local time.
9. Date: Enter current date; dd = day, mm = month, yy = year. If you use imperial units, set the date;
mm = month, dd = day, yy = year.
10. Units: Select metric (kg/cm/km) or imperial (lb/ft/mi) units.
11. Weight: Enter your weight. To change units, press and hold the LIGHT.
12. Height: Enter your height. In LB/FT format, first enter feet then inches.
13. Birthday: Enter your date of birth; dd=day, mm=month, yy=year.
14. Sex: Select Male or Female.
15. Settings OK? is displayed. Select Yes or No. Select Yes to accept and save settings. The cycling
computer will display time of day. Select No if settings are incorrect and need to be changed.
Press STOP to return to the data you want to change.
Use the Polar ProTrainer 5 software to enter all basic settings.

5. TRAINING
Wear the Transmitter
Wear the transmitter to measure heart rate.
1. Moisten the electrode areas of the strap under running water and make sure that they are well
moistened.
2. Attach the connector to the strap. Position the connector's letter L to the word LEFT on the strap
and snap the fastener. Adjust the strap length to fit snugly and comfortably. Secure the strap
around your chest, just below the chest muscles, and snap the second fastener.
3. Check that the wet electrode areas are firmly against your skin and that the Polar logo of the
connector is in a central, upright position.
4. To detach the connector from the strap, apply pressure with your thumb and forefinger and turn
your hand as indicated in the picture.
The Polar WearLink transmitter can be used with specific apparel that has built-in soft textile
electrodes. Wet the electrode areas of the apparel. Clip the connector of the transmitter straight onto
the apparel without the strap so that connector’s Polar logo is in an upright position.
Start Training
Wear the transmitter and attach the cycling computer to the bike mount.
1. Start heart rate measurement by pressing the OK button. The cycling computer goes into pause
mode.
2. Select the bike you are going to exercise with. Bike 1 is set as a default. Select Settings > Bike >
Bike 1 > OK. Select Other if you only want to record heart rate.
Only the bikes that are switched ON are shown on this selection list. For further information see Bike
Settings.
The number on the bottom, right hand corner indicates the bike that is going to be used. By pressing
Polar CS400 User Manual 11
and holding the DOWN button, you can switch the bike quickly or switch to heart rate recording only.
By pressing and holding the UP button you can switch the exercise quickly.
3. Within 15 seconds, your heart rate appears on the display. The frame around the heart symbol
indicates that transmission is coded. The cyclist symbol on the bottom, left hand corner indicates
that bike 1 or 2 is in use.
If you want to change or view different exercise settings before you start training select Settings >
Exercise. Select an exercise type or view exercise settings.

If you activate the AutoStart function, the cycling computer will automatically start and stop exercise
recording when you start and stop cycling. For further information on AutoStart, see Autostart: On / Off .
The cycling computer automatically chooses the bike you have used during the previous exercise.
4. Start exercising by pressing OK. The exercise type is displayed in the upper left-hand corner.
If the following message is displayed: (Exercise name) requires Speed/ Cadence* sensor. Turn Speed/
Cadence sensor on, your exercise requires this sensor to display speed/ cadence* data (e.g. you have
defined speed or cadence zones for the exercise). Select Yes to turn the sensor function on. If Exercise
displays updated is displayed, speed/ cadence* data will be shown during exercise.
* Optional sensor required.
