IP 240 Introduction

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.

• There is an overview containing the headings of the individual chapters at the beginning of

the manual.

• Each chapter is preceded by a breakdown of its subject matter.

The individual chapters are subdivided into sections and subsections. Bold face type is used for

further subdivisions.

• Pages, figures and tables are numbered separately in each chapter. The page following the

chapter breakdown contains a list of the figures and tables appearing in that particular

chapter.

Certain conventions were observed when writing the manual. These are explained below.

• A number of abbreviations have been used.

Example: Central processing unit (CPU)

• Footnotes are identified by a superscript consisting of a small digit (e.g. ”1”) or ”*”. The actual

footnote is generally at the bottom of the page or underneath a table.

• Cross-references are shown as follows:

”( Section 7.3.2)” refers to subsection 7.3.2.

No references are made to individual pages.

• Actions required from the user are introduced by the symbol .

• All dimensions in drawings etc. are given in millimetres (mm). This is followed by the value in

inches in parentheses. Example: 187 (7.29).

• Values can be expressed by binary, decimal or hexadecimal numbers. The number system is in-

dicated by a subscript; example: F000

• Especially important imformation is written in text boxes. A heading in the upper part of the

text box defines the meaning of the note.

Note

is important imformation on the product, the handling of the product or parts of

documentation that have to be observed very carefully.

Warning

means that loss of life, severe personal injury or substantial property damage can

result if proper precautions are not taken.
