4.2 How to navigate in the main menu

The numerous QuintSonic 7 functions can be accessed via the hierarchically structured user

menu. The main menu represents the highest menu level. From the main menu you can get

access to various submenus and their respective submenus or to other screens such as statistics

or parameter screens. In this section, a few examples are given to show you how to navigate

through the menu.

Press function key “Main menu” to call the main menu. Note: Some of the screens do not feature a
”Main menu“ function key. In such case, please press ESC repeatedly until you access a screen
featuring such key.

From the main menu, press arrow-up or -down key to select the

request

ed item, for instance “Setup”. Press OK to confirm. The selected

item will be called up.

The „Setup“ menu includes a submenu. Use arrow keys to select

“User Preferences” and confirm by OK to call up your selection.

The “User Preferences“ menu does not lead to submenus but it

includes a list of parameter options. The following section 4.3

provides more information on parameter options.

Press ESC-key to go back to the previous menu level. If you press ESC from the main menu, the

measure screen will appear. By means of the above navigation instructions you can move through

the complete menu and access any menu as requested.
