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.

CHARGING
The battery level is displayed in the Mio PAI app when Mio SLICE is connected. Both SLICE and the PAI app will
alert you when SLICE is low in battery.
Important: Make sure the two charging contacts on the back of the SLICE are dry. If they are wet, pat them gently
with a dry towel.
1. Plug the USB charger
into the USB port of your
computer.
2. Align the two charging
contacts on the back
of the SLICE to the two
charging pins on the USB
charger. The magnets in
the charger will help the
two pieces lock into place.
3. The screen will display
a charging icon to indicate
that the battery is charging.
Depending on the SLICE
battery level, it can take
a few minutes for the
charging icon to appear.
4. It will take approximately
2 hours to fully charge;
the display will show a
full battery icon. Each
full charge will provide
approximately 4-5 days of
normal use.

You can see the battery level of your
Mio SLICE in the Mio PAI app.
SLICE will display the following screens
to indicate its battery status:

TROUBLE WITH PAIRING MIO SLICE TO YOUR PHONE
Try the following tips if you have trouble pairing Mio SLICE to your smartphone:
• Check that you are connecting to the correct SLICE device. Before pairing is complete, SLICE is listed with
a 4-digit code appended to the name. Match the 4-digit code to your device serial number, found on the
back of your SLICE. E.g. If your serial number is “60P00014DCI”, SLICE will show up in the app as “SLICE-
014D”.
• Check that your phone is compatible with the Mio PAI app at mioglobal.com/compatibility.
• Turn off your phone’s Bluetooth. After a few seconds, turn Bluetooth on again. Retry the pairing process.
• Force close the PAI app and reopen it. Follow the app’s prompts to retry the pairing process.
• Force close all apps on your phone and reopen the PAI app. Follow the app’s prompts to retry the pairing
process.
• Perform a factory reset on the SLICE (refer to Resetting Mio SLICE & Pairing To A New Phone).
Note that this will erase all data stored on your SLICE.

good contact with your skin.
2. If you have a smaller wrist, wear
the SLICE higher on your forearm.
