A unique identification number (Unique ID) is given to each unit,
which is imprinted on the CD mechanism assembly. If and when
the mechanism assembly or Flash ROM (IC17) on the mechanism
board is replaced, it is necessary to write the Unique ID. For
details, refer to "How to Write the Unique ID" on Page 17.
