in the upper right corner flashes to indicate a working HART 

connection.

•   Rotate the knob to move the reverse video highlight to the 

desired unit.

•   Press and hold the knob to send the new value to the HART 

device, returning to the Modify Setup menu after displaying a 
reminder to change the loop to AUTOMATIC. An error is 
displayed if the HART device rejects the value for any reason.

•   Press MENU/EXIT to return to the Modify Setup menu in section 

6.7. A reminder to change the loop to AUTOMATIC is displayed 

first.
