For example, when the Main Menu is displayed on the top line, pressing F1 (Up) will scroll up through the possible
main menu selections while pressing F2 (Down) will scroll down through the possible main menu selections.
Pressing F4 (Enter) will cause the selection of the sub-menu displayed on lines two and three (such as Config Menu).
Scrolling through a sub-menu is performed in the same manner as scrolling through the Main Menu using the F1 and
F2 keys.
To return to the Main Menu, press the PREVIOUS FUNCTION key [Ü], as shown in Figure 3-3 on page 13.
When a parameter is encountered which is to be changed, pressing the F3 key (Alter) will cause the display of the
current parameter in a form which permits its modification.
When a specific set of parameters is available, the F1 and F2 keys can be used to scroll through the valid selections.
When the desired selection is displayed, pressing the F4 key (Enter) will cause selection of the new parameter. When
the parameter consists of numeric or free format characters, the Model 1200 keyboard can be used to enter the
parameter. Note that parameter alteration is not final until the session is completed with the EXIT AND SAVE command
from the Main Menu.
To complete parameter alteration, scroll through the Main Menu until the following display is presented, then press
F4 (Enter) to exit and save the altered parameters.
If parameter alteration is to be aborted (new parameters not saved), scroll through the Main Menu until the following
display is presented and press F4 (Enter) to quit without saving alterations. The QUIT or EXIT AND SAVE commands
must be initiated before turning off or disconnecting the 1200 Hand Held Terminal.
