My iHealth Edge doesn't turn on

1. Make sure the battery is sufficiently charged .
2. iHealth Edge remains in standby mode until you wake it up in order to maximize battery life.
   To exit the standby mode, place your wrist in front of you as if you wanted to watch the clock, and make a firm rotation of the wrist. Each rotation changes the display.
   You can also tap on the iHealth Edge screen.
   
3. If your iHealth Edge still doesn't turn on, try to make a Restart Complete.
