To adjust the input sensitivity level, remember that the preset menu contains the
instantaneous modulation level and that an indicator reads a level of 75 kHz. For a
correct adjustment, we therefore recommend you apply to the machine input a level
equal to the maximum level of your audio program and adjust the related trimmer
until the instantaneous deviation coincides with 75 kHz.
To adjust the level of the subcarrier inputs, you can follow a similar procedure, with
the help of option “x10” selected from the “Fnc” menu. With this option, the indicated
modulation level is multiplied by 10, therefore the broken-line indication of the preset
menu coincides with the 7.5 kHz deviation value.
For the stereophonic version, there is a specific menu separately indicating the Left
and Right channel levels with related nominal level indicators for the maximum
deviation of 75 kHz.

5.4 Software
The machine features a 2-line LCD which displays a series of menus. An overall
view of the machine menus is shown in fig. 5.1.
On the left-hand side of the display, depending on the case, there may be one or
more symbols:
The parameter indicated with the arrow can be modified.
The arrow indicates the current line, whose parameter cannot be modified. This
symbol is found in menus consisting of more than two lines as help with scrolling
the menu.
When the machine is switched on, the LCD displays the default screen, with a graphic
representation of the instantaneous modulation level and an indication of the direct
power value delivered:
