When the or – is pressed, the selected value is modified and saved immediately on the
permanent memory (EEprom). Unit shutdown in this phase, even if inadvertent, does not cause loss of the
set parameter.
The SET button is only used to exit the current menu and is not used to save any changes. Only in some
special cases described in 6 some values are implemented by pressing "SET" or "MODE".
