Hot Key
Use this key to quickly access important, user-selectable options when
connected to a HART-compatible device. Pressing the HOT KEY turns the
HART Communicator on and displays the Hot Key Menu. See “Customizing
the Hot Key Menu” in the Rosemount 275 HART Communicator manual for
more information.
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 HELP label may
appear above the F1 key. In menus providing access to the ONLINE MENU,
the HOME label may appear above the F3 key. Simply press the key to
activate the function. See your Rosemount 275 HART Communicator manual
for details on specific function key definitions.

Data Entry Some menus require data entry. Use the alphanumeric and shift keys to enter
all alphanumeric information into the HART 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 A-8). Do not press these keys
simultaneously, but one after the other.
