Motorola MT2000 用户手册

And still other screens list those features that perform a certain RSS function, such as servicing the radio or
printing the personality data.

The screens are organized in a tree-root fashion (Figure 2-9). Though this tree-root system is shown sideways in
the following picture, it shows how the whole system starts with a main root (MAIN MENU) at the left side and
branches outward from the main root. This branching grows deeper as you get closer to the precise screen which
contains the feature you want to program into the radio. 

Traveling from one RSS menu or screen to another is similar to the way a car must use the road system to drive
to the other side of a lake, instead of flying directly as a plane would. To move forward from one screen to
another, use one of the F-keys until you’ve reached the menu that contains the other screen you want. To back
up, use the F10 key. Each time you press F10 you retreat to the previous screen or menu, moving closer to the
MAIN MENU.
