Menu Function Types
There are two types of menu functions on the IDU-450; top-level menu
functions corresponding to the labeled button, and soft menu functions
indicated by menu tiles, which appear on screen. Soft menu function tiles
appear next to the appropriate IDU button or in the lower right corner when
use of the encoder is appropriate. Soft menu functions take precedence
over IDU button functions.
5.4.
Top-Level Menu
On the IDU-450, the top-level menu corresponds to the permanent label of
the IDU buttons and is active anytime no soft menu options appear on the
screen.
