Faulty Optic Module

I went throughthe manual and it states:

The replacement instructions for the Optic
Module, spare part number*
CM+9 5170 2750 0, are enclosed to the spare
part.
* The last digit in the order number indicates the
spare part revision at release of this document.
When ordering, the actual revision of the spare part
is delivered.

That makes it sound like that the instructions are included when you order the part.
