The following describes some frequently used navigation ele-
ments in the soft menus.
In the Fig. 2.8 there are two basic soft menu elements for choosing
something are shown. To select from the rst three you just need
to press the soft key beside and the element is active (shown as
blue color). A second kind of selecting is shown on the lower two
menu entries. Pressing the respective soft key toggles between
the two choices, again the active selection is marked blue.
The menus are used as shown in Fig. 2.9 if they concern func-
tions which have either to be switched on or where values have
to set. The choice is between OFF and the value presented. The
round arrow in the right corner of the menu window points to
the universal knob which is to be used for selecting the value. If
there is a lower menu level, this will be indicated by a small tri-
angle in the right lower corner of the respective menu point.
If there are further pages on the same level, the lowest menu
point will be used for navigation. It shows the number of menu
pages on this level as well as the activated number of pages.
Pushing the respective soft menu key will advance by one page,
after the last page the rst one will follow.
