When you press twice on the ESC button while you are in the predefined menu,
the following selection view is displayed, and from this view it will be then possible
to enter to all the other menus:
To enter one of the submenus, select the name (that will be enhanced by a
flashing cursor) with the RIGHT or LEFT push-buttons and then press the ENTER
button.
If on the contrary, you wish to return to the predefined menu, you just have to press
again the ESC push-button.
In some cases, on the left side of the menu an arrow can appear. It indicates that
it is necessary to indicate the current line selected. When the arrow is full, the
parameter can be modified, while when it is empty, the parameter can only be
viewed.
6.4.1 Functioning menu (Fnc)
From this menu the user can set the deviation display mode, he can switch on or
inhibit the muting mode.
In order to intervene on one of the three keys, select the corresponding line with
the “UP” and “DOWN” buttons and then press and keep the ENTER button pressed
until the order is accepted. In this way the Pwr setting will go from On to Off or
viceversa and the Mod setting will go from “X1” to “X10” or viceversa.
In “X10” mode the indication of the instantaneous deviation is multiplied by 10, this
is why the hachured indicator on the predefined menu coincides with the 7,5 kHz
value instead of 75 kHz. This visualization mode is useful when the user wants to
have low deviation levels displayed, for instance when they are provoked by the
pilot tone or the subcarriers.
As indicated in the introduction, the transmitter offers the possibiliy to the user to
set the muting mode. “MUTE OFF” indicates that the muting was not activated,
therefore the received signal is situated at the audio outputs. “MUTE ON” indicates
that the muting is activated, therefore the audio outputs are muted.
