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

”)
to less than 1 MHz by varying the input frequency using
the
buttons.

tio of the signal received.
