Start exercising with your Polar S410

How to prepare the wrist receiver

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.
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 and personal user settings.
Polar S410 has various functions that you can use according to your personal training needs. For more information, see section Modes and their functions.
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

Attach the transmitter to the elastic strap.
Adjust the strap length to fit snugly and comfortably. Secure the strap around your chest, just below the chest muscles, and buckle it.
Lift the transmitter off your chest and moisten the grooved electrode areas on the back.
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

Begin with the display that shows the time of day.
Keep the wrist receiver within 1 metre / 3 feet of your transmitter.
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.
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.
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

Press the stop button. The stopwatch and other calculations stop. The heart rate measuring continues, although exercise data is no longer recorded.
Press the stop button again. The heart rate measuring stops. The receiver shows the Time of day display again.

After exercising

Carefully wash the transmitter with a mild soap and water solution.
Rinse it with pure water.
Dry the transmitter carefully with a soft towel.
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
