function of scrolling the screens
of a group. From the last one,
the display returns to the first

sor is in a numerical field, the
buttons increase or decrease
the value that the cursor is posi-
tioned on. If it is a selection field,
pressing the UP / DOWN buttons
displays the options available
(for example, Yes / No).

In the value setting screens, the
first time this button is pressed,
the cursor moves on to the first
entry field. Subsequent press-
es confirm the value entered
and move the cursor to the
next field. After the last field, it
returns to the HOME position.
