The display (1), with its extensive text and
graphics mode, is almost self-explanatory,
allowing easy operation of the controller.
Entries are made using four keys (2+3),
which are assigned to different functions
depending on the situation. The “esc” key
(3) is used to cancel an entry or to exit a
menu.
If applicable there will be a request for
confi rmation as to whether the changes
which have been made should be saved.
The function of each of the other three
keys (3) is shown in the display line di-
rectly above the keys; the right-hand key
generally has a confi rmation and selection
function.
Examples of key functions:
+/- = increase/reduce values
/ = scroll menu down/up
yes/no = approve/reject
Info = additional information
Back = to previous screen
ok = confi rm selection
Confi rm = confi rm setting
