B-7
Model 275 HART Communicator
Function Keys
Use the four software-defined function keys, located below the LCD, to
perform software functions. On any given menu, the label appearing
above a function key indicates the function of that key for the current
menu. As you move among menus, different function key labels appear
over the four keys. For example, in menus providing access to on-line
help, the
label may appear above the F1 key. In menus providing
access to the Online Menu, the
label may appear above the F3 key.
Simply press the key to activate the function. See the Model 275 HART
Communicator Product Manual (Rosemount publication no.
00809-0100-4275) for details on specific function key definitions.
Alphanumeric and Shift Keys
The alphanumeric keys (Figure B-4) perform two functions: the fast
selection of menu options and data entry.

Communicator Alphanumeric and
Shift Keys.
Data Entry
Some menus require data entry. Use the alphanumeric and shift keys to
enter all alphanumeric information into the communicator. If you press
an alphanumeric key alone from within an edit menu, the bold
character in the center of the key appears. These large characters
include the numbers zero through nine, the decimal point (.), and the
dash symbol (—).
To enter an alphabetic character, first press the shift key that
corresponds to the position of the letter you want on the alphanumeric
key. Then press the alphanumeric key. For example, to enter the letter
R, first press the right shift key, then the “6” key (see Figure B-6). Do
not press these keys simultaneously, but one after the other.
