Note: you must turn off the phone to exit after this test, because of the last function, "transfer user data" which doesn't work as "standard"....You can use this mode only to transfer all Calender, Profile and Callers Group Information to another phone (eg. if you are replacing phone or configuring phones for use within your company or when a particular phone doesn't works correctly )
