Figure 48. Marine scan settings
o
“Time (def.)” hotkey (s. Figure 48, 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. Figure 48, 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. Figure 48, 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. Figure 48, 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.
7.2.4.3 Exclude List (for “Marine Scan” and “Scan List” modes)
The “Exclude List” (s. Figure 24, 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. Figure 47, 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.
