Setting the input frequency
If three dots “
…
“ appear in the second line of the display,
the cassette is in the “
station search
” mode. Please wait until
the process has finished.
Once the HF receiver has synchronised to the input signal,
any offset to the target frequency is displayed in MHz, e.g.
“
– 1.8
”.
If a question mark “
?
” appears in the second line of the dis-
play, there is no input signal present. Check the configuration
of the antenna system and head-end station as well as the
preceding settings of the cassette.
• Use the

digit of the frequency displayed to be set.

to set the input frequency.
• Set the frequency offset shown in the display (e.g. “
– 1.8
”)
to less than 1 MHz by varying the input frequency using
the
buttons.

CN 12
” display indicates the signal to noise ra-
tio of the signal received.
