o
“Time (def.)” hotkey (s. Fig. 42, position 1) defines the behavior of the marine scan
algorithm if the active frequency (signal level > squelch level) has been found.
If this hotkey is pressed, the default time of 30 seconds will be adopted after confirming
this setting with “OK”. Marine scan algorithm will stay for the default time of 30 sec on
an active frequency before continuing with scanning of the lower marine band.
o
Pressing the hotkey “Edit Time” (s. Fig. 42, position 2) will open a dialog for editing the
time of staying on the actively received frequency before continuing with the scan
procedure.
o
Pressing the hotkey “Signal>Sql.” hotkey (s. Fig. 42, position 3) defines the time of
staying on the actively received frequency before continuing with the scan procedure. If
this setting is confirmed, the scanning procedure will stay on the actively received
frequency as long as the signal level is higher than the squelch level.
o
If the hotkey “Endless” (s. Fig. 42, position 4) was pressed and confirmed with “OK”,
the marine scan algorithm will stay on the actively received frequency as long as the
user terminates the scan or skips the current frequency.
6.2.4.3 Exclude List (for “Marine Scan” and “Scan List” modes)
The “Exclude List” (s. Fig. 41, position 4) is a dialog that allows defining single frequencies or
frequency ranges that are to be excluded from the scanned frequency ranges for scan modes
“Scan List” and “Marine Scan”.
Due to generating the scan algorithms in the AU (that always run through all the defined
frequencies of the mode without the possibility of skipping), in case of signal reception of the
“Exclude List”-frequency, this frequency will not be completely suppressed but there will be a
short bearing indication. After less than one second, the indication interrupts and the marine
scan procedure continues immediately with the next frequencies of the defined band.
o
After pressing the hotkey “Edit Exclude” on the “Scan” page (see e.g., Fig. 41, position
4), the dialog for editing the “Exclude List” will be opened. In the case of first opening
this dialog, all fields will be empty.

To insert a new frequency/channel or a range of frequencies/channels, press the
hotkey „New Freq.“ (s. Fig. 43, position 1). The dialog for entering a new frequency will
