2.5. MAN-MACHINE INTERFACE (HMI)

The DBF system includes as standard a 20 key keyboard and a 2-line liquid crystal display (LCD) with 16

characters per line. This display has highly reliable LED diode back lighting (the screen brightness can be adjusted
on the rear of the front board).

By means of this interface the user can change the settings, display measurements, carry out operations

and access information stored in the unit. The functions of this local interface and how to use it are described in
the section KEYBOARD AND DISPLAY.
