Training with your Polar Loop Crystal

Polar Loop Crystal tracks all of your activity. To get even more out of your daily sports, the Polar Bluetooth Smart® heart rate sensor is an optional, but a perfect match for Polar Loop Crystal.

With the heart rate sensor you get more information about your training. You can see your heart rate accurately and in real time in your Polar Loop Crystal. In addition to the heart rate, you see the main effect of your training, and you can focus on what you want to achieve - burning fat or improving fitness. This feature is called Energy Pointer. For more information, see Energy Pointer.

By using a heart rate sensor, you can track your cycling sessions much more accurately. When you wear a heart rate sensor, it shows up in the Polar Flow web service as a training session after you've synced your data.

We recommend using Polar H7 Bluetooth Smart® heart rate sensor. We cannot guarantee full compatibility with other manufacturer's heart rate sensors.

Wearing a Heart Rate Sensor

  1. Moisten the electrode area of the strap.
  2. Tie the strap around your chest, just below the chest muscles, and attach the hook to the other end of the strap. Adjust the strap length to fit tightly but comfortably.
  3. Attach the connector to the strap.
  4. Check that the moist electrode area is firmly against your skin and that the Polar logo of the connector is in a central and upright position.

 

 

Detach the connector from the strap, and rinse the strap under running water after every training session. Sweat and moisture may keep the heart rate sensor activated, so also remember to wipe it dry. For more detailed caring instructions see Taking care of your Polar Loop Crystal.

Pairing a Heart Rate Sensor

Before you start training with the heart rate sensor, it has to be paired with your Polar Loop Crystal.

  1. Wear your compatible heart rate sensor. Make sure the electrode areas of the strap are moistened. If necessary, see further instructions from the heart rate sensor's user guide.
  2. Bring Polar Loop Crystal right next to the sensor.
  3. Tap the Polar Loop Crystal touch button and wait until the LED display turns off. Then wait a couple of seconds until PAIRED scrolls on the display.

Now your current heart rate and EnergyPointer are added to the display rotation.

If PAIRED doesn't appear on the display, repeat steps 2-3, and make sure none of your clothing is there between Polar Loop Crystal and the heart rate sensor.

If you have problems with pairing, visit support.polar.com/en/support/Loop_Crystal for further instructions.

Start the Training

Note that Polar Loop Crystal can't record heart rate in water. That is because the Bluetooth Smart® transmission doesn't work in water.

To start a heart rate training session, wear your heart rate sensor and Polar Loop Crystal. Tap the touch button and wait until the LED display turns off. Then wait a couple of seconds until your heart rate appears on the display.

 

You can't start a heart rate training session when Polar Loop Crystal is syncing data with the Polar Flow mobile app. Wait until the syncing sign disappears before starting a training session.

While you train with a heart rate sensor, you can't sync Polar Loop Crystal with the Polar Flow mobile app. You can sync your data after you've stopped the training session.

Heart Rate Guidance During Training

Tap the touch button to view the data during training. Your current heart rate is shown in beats per minute (bpm) figures.

Wait for two seconds and the display will show the current main effect of your training - fat burning or improving fitness. For more information, see Energy Pointer.

FAT BURN

In fat burn zone, training intensity is lower, and the source of energy is mainly fat. Therefore, fat burns efficiently and your metabolism, mainly fat oxidation, increases.

FIT

In fitness zone, training intensity is higher and you are improving your cardiovascular fitness i.e. strengthening your heart and increasing blood circulation to muscles and lungs. The main energy source is carbohydrates.

Stop the Training

To stop recording the session, untie the strap from your chest and detach the connector from the strap.

Remember to detach the connector from the strap to cut the connection between the heart rate sensor and Polar Loop Crystal. Leaving the connector attached consumes the battery of your Polar Loop Crystal.

After removing the heart rate sensor, wait two minutes before trying to use it with any other device or software.

After training, your data is synced automatically to Polar Flow mobile app, if you've taken the app into use and it is running on your mobile device.
