Be sure to consult your doctor before beginning a new exercise program.
While Mio Slice provides accurate heart rate measurements, it is not a medical device. The SLICE and USB charger contain strong magnets. If you use a pacemaker, defibrillator, or other implanted electronic devices, consult your doctor before using a Slice. See Battery Care for important battery care and battery safety information.
YOUR MIO SLICE

PAI (PERSONAL ACTIVITY INTELLIGENCE)
PAI is revolutionary new system that turns your heart rate data into a single, personal score, showing how much activity you need to stay healthy. Everyone's goal is the same, to keep your PAI score above 100 over a 7-day rolling window to maintain optimal health, but what it takes to achieve that goal is a personalized experience.
PAI points are calculated based on your heart rate data and personal profile. To earn more PAI points, increase the intensity of whatever activity you choose to get your heart rate up.
Your PAI Score and PAI Points Earned Today can be found anytime on your Mio SLICE and in the Mio PAI app.
Learn more about PAI at mioglobal.com/PAI.

AUTOMATIC HEART RATE SAMPLING
Mio SLICE monitors your activity level 24/7 to automatically adjust its heart rate sampling rate. When your heart rate rises, SLICE will increase its sampling rate to ensure all your activity is captured accurately.
SLICE has four heart rate sampling rates:
- Rest: SLICE captures your heart rate every five minutes.
- Low Intensity: SLICE captures your heart rate every minute.
- Moderate to High Intensity: SLICE captures your heart rate every second, continuously
- Sleep: SLICE analyzes your sleep, captures your heart rate every five minutes, and measures your resting heart rate. Note that this will erase all data stored on your SLICE.
In addition, SLICE will capture your heart rate each time you wake its display or open the Mio PAI app.
WORKOUT MODE
To record an activity, put Mio SLICE into Workout Mode by pressing down the button for 2 seconds. SLICE will display "GO!", then start the chronograph timer. In Workout Mode, SLICE uses high intensity sampling rate, capturing your heart rate every second.
SLICE will display screens specific to the current activity session:
