4. BACKLIGHT pushbutton, see Fig. 9.
The BACKLIGHT pushbutton turns on the backlight. (All other
pushbuttons turn on the backlight when pressed once; when
pressed a second time, the function is initiated.) If no
pushbutton is pressed for a two-minute period of time, the
backlight turns off.
5. SAVE pushbutton, see Fig. 10.
The SAVE pushbutton enables users to identify the
selectable message they want to view on power restoration.
The second line selectable message is restored to the most
recently saved selection when power returns. The
SAVE function is performed by pressing and holding
the SAVE pushbutton. The second line of the display
briefly notes " ... SAVING ..." to confirm that the pushbuttons
were pressed.
