1.1 Brief Description
These instructions are a brief version intended for end consumers. Only the functions intended for this user group are
described here. An overview of all functions is contained in the document “Basic Documentation for CS 500” (Art. no.

Information menu.
You access the parameter names or setting lines via main menus (home page) and submenus.
The order in which the menus for the individual parameter names or setting lines are selected is also explained in the
