How can I tell if the device is in Airplane (flight) mode.

A small airplane icon will appear in the top right corner of the therapy device. If "Airplane mode" has been enabled, the user will be alerted by an on-screen message that this mode is enabled when next they power on the device. The alert will ask if they want to disable the mode. This message will appear every time the device is powered on with "Airplane mode" enabled.
