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.
