Code designition in the service manual
The code designition in the service manual (N Series) has been changed
Nowdays the basic structure for the subgroup is divided according to subject matter.
XX1 Technical data, technical specifications, training material
XX2 Maintenance
XX3 Fault finding
XX4 Special tools
XX5 W o rk instructions
Every subject matter contain sub components (max. quontity 99)

Pictures include index numbers (for example fig001). Numbering helps to find certain picture. All groups has an own index
numbering and pictures are indexed starting at 001. Index numbers may not go in order.
Reason for change
Electrical functions and electrical components have been divided into their function based subgroubs to improve fault finding
and function based structure
In order to understand entire function, it’s easier to find all necessary information from one place.
Technical data and training material leads into understanding of the function, thereby it is easier to do fault finding. When the
fault has been located service can be made.
