4. THE KEYPAD AND THE DISPLAY
The user interface consists of a keypad with LCD display and POWER, COMMUNICATION and ALARM LEDs as seen in
Figure 3.
The display shows the values and the statuses of the device, with indications on the functionality of the various
parameters. The functions of the keys are summed up in Table 1.
The MODE key allows you to move on to the next items in the same menu. Holding it down for at least 1
sec allows you to skip to previous menu item.
The SET key allows you to leave the current menu.
Decreases the current parameter (if it is an editable parameter).
Increases the current parameter (if it is an editable parameter).
Holding down the "+" key or the "-" key allows the automatic increase/decrease of the parameter selected. After the "+"
key or the "-" key has been held down for 3 seconds, the automatic increase/decrease speed increases.
When the + key or the - key is pressed the selected value is modified and saved immediately in the permanent
memory (EEprom). 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 necessary for saving the changes made. Only in
particular cases described in the following paragraphs are some values updated by pressing "SET" or
"MODE".

The complete structure of all the menus and of all the items of which they are composed is shown in Table 4.
