3. All-Day Activity Tracking

Your ALPHA 2 must have firmware version 1.05 or higher to enable Activity Tracking. Check your Mio ALPHA 2 firmware version in Mio GO, at the bottom of the device Setup screen.

If your firmware version is lower than 01.05, update your firmware by following these instructions for iOS and for Android.When the firmware update is complete, enable Activity Tracking in device settings in Mio GO and sync to your ALPHA 2 so it can start capturing your daily activity.

Your Mio ALPHA 2 is now ready to use!

When Activity Tracking is enabled, Mio ALPHA 2 tracks and displays steps, calories, distance, and goal progress. You can customize your goal in Mio GO.

To review All-Day Activity Tracking data on your Mio ALPHA 2, press (A). To scroll through your activity tracking data, press (A) again.

The values are reset to 0 at midnight each day. ALPHA 2 calculates calories from midnight, based on your profile information. The body consumes calories even while at rest, so you may see calories on your device before you put it on in the morning.

4. Heart Rate Monitoring: Wearing the Mio ALPHA 2

1. Tighten your Alpha

To get accurate heart rate, wear ALPHA 2 snugly, about 2 finger widths above your wrist bone. The optical sensor on the back should make good contact with your skin.

  • If you have a smaller wrist, wear ALPHA 2 higher on your forearm.
  • For cyclists or users with concave wrists, wear ALPHA 2 higher and on the underside of your forearm.

We recommend warming up for a few minutes before you begin to track your heart rate, particularly if you have cold hands or poor circulation.

Note: Wash Mio ALPHA 2 regularly with mild soap and water. Make sure to allow both your arm and ALPHA 2 to dry completely before resuming wear.

  1. Turning on Heart Rate

Find your heart rate by pressing and holding (B). Hold your arm still while Mio ALPHA 2 searches for your heart rate.

If you see “--” on your display, press and hold (B) to stop heart rate mode. Check watch placement and start over (See Heart Rate Monitoring: Wearing the Mio Alpha 2).

  1. Recording your Workout

Start: Once your heart rate is showing, press and hold (B) to record your workout and start the timer.

Scroll: Press (A) to scroll through workout metrics.

Lap: To take a lap time, press (B).

Pause: Press and hold (B) to pause the timer. Press (B) again to resume.

End Workout: Pause your workout (see above), then press and hold (B) to end your workout.
