4 - THE KEYPAD AND THE DISPLAY
Figure 12: Aspect of the user interface
The user interface is composed of a keypad with 128x240 pixel LCD dis-
play and with POWER, COMM, ALARM warning leds as can be seen in
Figure 12.
The display shows the values and the statuses of the device, with indica-
tions 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.
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 (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".
