5-4 Running Applications
Menu and Sub-Menu
Screens
Menus and Sub-Menus provide a convenient method of accessing a
large number of display screens.
Main Menu
Every application has a Main Menu screen. The Main Menu is the first
application screen displayed after an initial power-up or reset.
The Main Menu provides access to the next level of screens and
Sub-Menus.
To access the Main Menu, press the [MENU] key. Pressing this key at
any time displays the Main Menu.
Sub-Menus
Sub-Menu screens function like the Main Menu. The only difference is
that you must navigate through the other screens or use assigned
function keys to access the Sub-Menus.
Security Screens
Security screens limit access to parts of an application. Although the
text on a security screen may be changed by the application designer,
many applications will use the default text:
A security code is a series of 1 through 8 digits. Each security screen
can have up to 3 code entries. Entering any one of the codes provides
access.
To enter a security code, use the numeric keypad. An asterisk (*) is
displayed for each number entered. Press [
] after the entire code is
entered.
If a valid security code has been entered, the next linked screen is
displayed. If an invalid security code has been entered, an error
message appears. Once you acknowledge the error condition by
pressing [
], you can re-enter the code.
