  • Use the included iOS or Android cord to connect your iOX device to your phone. 

  • Open your iOX app. Insert one index finger into the iOX with your finger nail touching the top of the inside of the iOX.

  • The pad of your index finger will touch the bottom of the inside of the iOX.

  • Do not insert your finger into the probe upside down.
