The values indicated are "readings", and therefore cannot be modified (remark the
empty triangle). In order to modify the power setting, use the predefined menu as
described formerly.
5.4.3 Power Amplifier menu (P.A)
This view, composed of three lines that can be scrolled with the 'UP' and 'DOWN'
buttons, shows to the user the values corresponding to the power amplifier of the
unit:
• Voltage (VPA)
•
Absorbed current (IPA)
5.4.4 Menù Impostazioni (Set)
This menu enables to read and set the working frequencies.
When you press the ENTER button, it will be possible to modify the setted frequency
with the 'UP' (the frequency increases) and 'DOWN' (the frequency decreases).
After a new frequency value was setted, press the ENTER button to confirm the choice;
the exciter will unlock from the current frequency (the LED LOCK switches off) and
will lock to the new working frequency (the LOCK LED lits up). On the contrary when
you press ESC or when you let the timeout passes by, the frequency will remain
setted at the last value memorized.
5.4.5 Mix menu (Mix)
This menu enables to set the path of the unit on a serial bus connection of the type

C:
The I
2
C AC path is important when the exciter is connected to an RVR transmission
system which allows the use of this protocol. We recommend not to modify it with no
reason.
