Introduction S5-115F Manual
Conventions
In order to improve the readability of the manual, a menu-style breakdown was used, i.e.:
• The individual chapters can be quickly located by means of a thumb register.
• At the front of the manual is an overview containing the headings of the individual chapters.
• Each chapter has its own detailed table of contents.
The individual chapters are subdivided into sections and subsections. Bold-face type is used for
further subdivisions.
• Figures and tables are numbered separately in each chapter. The page following the chapter
table of contents contains a list of the figures and tables appearing in that chapter.
Certain conventions were observed when writing the manual. These are explained below.
• A number of abbreviations have been used.
Example: CPU (central processing unit)
• Footnotes are identified by superscripts consisting of a small digit (e.g. ”
1
”) or ”*”. The actual
footnote is generally at the bottom left of the page.
• Cross-references are shown as follows:
”( 7.3.2)” refers to subsection 7.3.2.
No references are made to individual pages.
• Dimensions in drawings are given in mm with the value in inches given in brackets. Example:
187 (7.29).
• Values may be given in binary, decimal or hexadecimal numbers. The number system used is
indicated in each case with a subscript, e.g. F000
H
.
• Information of special importance is printed in black-framed ”windows”.
