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 .
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.
u (Full arrow) - The parameter highlighted by the arrow can be modified. This
symbol is present in menu composed of more than two lines as an help in the
scroll menu.
www (Three empty arrows) - The parameter highlighted by the arrows is in phase
of modification.
w
(Empty Arrow) - The arrow points out the current line, the parameter of which
cannot be modified. This symbol is present in the menus made up of more than
two lines to help scroll the menu.
When the unit is switched on, the LCD display shows the predefined view, with the
graphical representation of the instantaneous modulation level and the indication
of the value of the direct power erogated:
The bottom line gives the instantaneous reading of the received signal level on
analog scale, while the bar indicates the squelch level set. To increase the level,
press the RIGHT / DOWN button or decremented by pressing LEFT / UP button.
As the set level increases or decreases, the bar lengthens or shortens to display
the current setting. Once you reach the desired level, press ENTER to confirm
and exit the default menu. Note that the set value is stored anyway, so if you
press ESC or if you leave the timeout time without pressing a button, the power
will remain to the last set level.
In case the RF signal is lower than the squelch threshold set, the receiver outputs
are placed in MUTE and BNC interlock is closed.
