RC3 GPS User manual


Training Computer Parts

With an integrated GPS unit, the Polar RC3 GPS training computer provides the following data in all outdoor sports using Global Positioning System (GPS) technology:

  • speed

  • distance

  • altitude

  • ascent

  • descent

  • route information (at polarpersonaltrainer.com web service)

There are at least 24 active GPS satellites orbiting around the earth. The signals that GPS satellites transmit to the earth indicate the location of the satellites. The training computer receives the signals and determines your location by measuring the distance between itself and the satellites.

The training computer combines the signals from at least four satellites to get a reliable speed, distance and location reading. To calculate the altitude, the training computer requires a minimum of six satellite signals.

Connect the training computer to your computer with a USB cable to charge the battery and to transfer data between the training computer and the polarpersonaltrainer.com web service.

Available Accessories

With the help of Polar accessories, you can enhance your training experience and achieve a more complete understanding of your performance.

The RC3 GPS training computer is compatible with Polar H2 and H3 heart rate sensors. The comfortable heart rate sensor detects your heart rate accurately from the heart's electrical signals and sends the data to the training computer in real time.

The heart rate sensor consists of a connector and a strap.

If you bought a set which does not include a heart rate sensor, turn it off in settings for the Sport Profiles. For instructions, see Sport Profile Settings.


Optional Polar s3+ stride sensor* helps you to improve your running technique. It wirelessly measures speed/pace, distance, running cadence, running index and stride length, whether you train indoors or out.


Optional Polar CS cadence sensor W.I.N.D.wirelessly measures cycling cadence, i.e. your real-time and average pedaling rate as revolutions per minute.


Optional Polar CS speed sensor W.I.N.D.* wirelessly measures cycling distance and your real-time, average and maximum speeds/paces.

Data from all compatible sensors is sent wirelessly to the training computer over the 2.4 GHz W.I.N.D. technology, proprietary to Polar. This eliminates interference during training.

*When using the training computer with s3+ stride sensor or CS speed sensor W.I.N.D., the training computer retrieves speed and distance data from the sensor and the GPS will only be used for location and route tracking.

Fitness Test

To train right and to monitor your progress, it is important to know your current fitness level. The Polar Fitness Test is an easy and quick way to measure your cardiovascular fitness and aerobic capacity. The test is performed at rest. The test result is a value called OwnIndex. OwnIndex is comparable to maximal oxygen uptake (VO2max), which is a commonly used aerobic capacity measure. For more information, see 9. Polar Fitness Test.
