By means of the programming unit, the
input and output channels (or central fre-
quencies), the frequency offset (if required),
the output level and the slope of the signal
and the are selected. This information is
recorded into the channel processor until a
new programming procedure takes place.
It also provides an indication of the input
signal level, there indicating whether it is
below the level for which a preamplifier
would be required.
The programmer consists of four buttons:
: The button that changes the program-
ming menu and recording information.
: The button that allows the selection of a
digit within a specified programming
menu. It also carries out the change from
the normal menu to an extended menu.
: The button for increasing the value of
the selected digit.
: The button for decreasing the value of
the selected digit.
Using these four buttons, all the program-
ming functions are carried out.
The connection between the programmer
and the channel processor can be made with
the processor switched either ON or OFF.
It must always be switched ON before
starting the programming procedure.
