Pair and Sync

  • Pair and sync mobile device: Pair mobile devices with your A300. For more information, see Pairing. Sync data from your A300 to a mobile device. Tip: You can also sync by pressing and holding the BACK button in the time view.
  • Pair other device: Pair heart rate sensors with your A300. For more information, see Pairing.
  • Remove pairings: Remove pairing with a heart rate sensor or mobile device.

Flight mode

Choose On or Off

Flight mode cuts off all wireless communication from the device. You can still use it to collect activity, but you cannot use it in training sessions with a Bluetooth® Smart heart rate sensor nor sync your data to the Polar Flow mobile app because Bluetooth® Smart is disabled.

Inactivity Alert

Set the inactivity alert On or Off. See more information in 24/7 Activity Tracking.


Choose Metric (kg, cm) or Imperial (lb, ft). Set the units used to measure weight, height, distance and speed.


By default, A300 only comes in English. You can choose another language when setting up your A300 at, or change the language later in the Flow web service.

To add another language later:

  1. Go to and sign in.
  2. Click your name/profile photo in the upper right corner, choose Products, and then Polar A300 Settings.
  3. Choose a language from the list.
  4. Sync the data from Flow web service to your A300 with FlowSync.
