When adjusting the sensitivity level of the inputs, keep in mind that the instantaneous
modulation level is given in the predefined menu and that an indicator signals the 75
kHz level. To get a proper adjustment, we recommend you put a level signal on the
machine's output equivalent to the level of its own audio program and adjust the
relative trimmer until the instantaneous deviation coincides with the indication of 75
kHz.
To adjust the levels of the inputs of the subcarriers, you can use a similar procedure
while getting help from the "x10" option that can be selected from the “Fnc” menu.
With this option, the modulation level indicated is multiplied by a factor 10 so the
drawn indication of the predefined menu coincides with a deviation value of 7.5 kHz.
There is a special menu in which the levels of the Right and Left channels are indicated
separately with the relative indicators of the nominal levels for the maximum deviation
of 75 kHz.

5.4 Software
The machine is provided with a two-line LCD display where a set of menus is
shown. An overall view of the machine's menus is given in figure 5.1.
One of the following symbols may be present on the left side of the display, depending
on the case:
(Cursor) - The cursor indentifies the selected menu where you can have access.
(Full arrow) - The parameter highlighted by the arrow can be modified. This symbol
is present on menu with two rows or more as navigation assistant.
(Three empty arrows) - The parameter highlighted by the arrows is in phase of
modification.
