3. THE MINOR DEVICE CLASS FIELD
The 'Minor Device Class field' (bits 7 to 2 in the CoD), are to be interpreted only in
the context of the Major Device Class (but independent of the Service Class field).
Thus the meaning of the bits may change, depending on the value of the 'Major
Device Class field'. When the Minor Device Class field indicates a device class, then
the primary device class should be reported, e.g. a cellular phone that can also work
as a cordless handset should use 'Cellular' in the minor device class field.
