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.

The QUIT or EXIT AND SAVE commands must be initiated before turning off or disconnecting the 1200 Hand Held Terminal.
