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.
