Restart complete

If you notice abnormal behavior of your iHealth Wave (connection trouble, display...), try to perform a Restart Complete.

Plug your iHealth Wave on the USB charger provided as if you wanted to charge the battery.
Press and hold the button on the side of the charger until "Restart Complete" appears on the screen of the iHealth Wave (about 10 seconds).

Note - A Restart complete doesn't delete settings such as alarms and doesn't delete the data you haven't sync yet.
