7.4 Menu Organization
7.4.1 Default menu (MAIN)
This is an information screen; it shows the main amplifier measures, most of this
cannot be modified. Only RF Status, Frequency and Power Output are quickly
modifiable from this menu.
If the illumination of the display is turned off, the first pressure or rotation of the
encoder cause the lighting.
To change the editable parameters press the encoder, turn until the indicator
is highlighted on the desired menu and then press again to confirm. The
setting of the value is now possible by the rotating of the encoder.
After having modified the value of a parameter, the cursor goes on blinking for
approximately 10 seconds, waiting for confirmation from the user. If the user doesn’t
confirm the new value (i.e., the button is not pressed), the cursor stops blinking
and remains on the selected parameter.
To access to the Maintenance submenus (chap. 7.4.2) or to the Administrator
submenus (see chap. 7.4.3) press the encoder, turn until the indicator is highlighted
on the desired menu and then press again to confirm.
If no controls are operated through the encoder during 2 minutes, the exciter
returns to this menu and after 5 minutes of inactivity the display lighting will be
turning off.
