GENERAL OPERATING PRINCIPLES
3.1.2.1
KEYPAD LAYOUT AND PROTOCOL
MFC-CB has a 4 x 4 keypad for local operator access to direct functions, function
menus and for data entry.
1. The Editing and Execution keys are for
execution, suspending execution,
backing up in menus and editing entries.
2. The Menu/Data keys provide access to
function menus from the MAIN run
screen. The menu name is on the
bottom half of the key. The SETUP
menu is for more frequently used
functions. The SPECIAL menu is for
functions that are not generally used as
a part of day to day operation. These keys
enter numerical values when editing.
3. The Function/Data keys allow very
commonly used functions to be
accessed directly from the MAIN run
screen by a single keystroke. The name
of the function is on the bottom half of
the key (see Section 3.1.2.5). These keys
enter numerical values when editing.
