When the + key or the - key is pressed the selected value is
modied and saved immediately in the permanent memory (EE-
prom). If the machine is switched off, even accidentally, in this
phase it does not cause the loss of the parameter that has just
been set.
The SET key is only for leaving the current menu and is not nec-
essary for saving the changes made. Only in particular cases
described in the following paragraphs are some values updated
by pressing “SET” or “MODE”.

Menus
The complete structure of all the menus and of all the items of which they
are composed is shown in Table 3.
Access to the menus
The various menus can be accessed from the main menu in two ways:
1 - Direct access with a combination of keys.
2 - Access by name with a drop-down menu.
4.1 Direct Access with a Combination of Keys
The desired menu can be accessed directly by pressing simultaneously
the appropriate combination of keys for the required time (for example
MODE SET to enter the Setpoint menu) and the various items in the menu
are scrolled with the MODE key.

keys.
