This item selects one of the following scan functions.
Channel scan and channel resume scan search 5
channels around a user selected channel or search
all ITU channels in the band when an ITU channel is
selected.
Programmed scan (optional) searches signals within
the frequency range and activates slowly while
squelch is open and fast while squelch is closed.
(5) Scan speed
This item adjusts the scan speed (rate at which chan-
nels are searched). The scan speed can be set from
1 to 10 with "1" being the fastest and "10" being the
slowest.

The lower half of the display can be set to display a
programmable channel name or a receive frequency
according to operator needs.

This item selects the passband width for A1A (CW),
FSK or J2B mode.

NOTE: When "on" is selected without optional fil-
ter installation, the Marine and General versions
do not function in these modes. The GMDSS ver-
sions can use "on" as standard.
(8) FSK shift frequency
Several shift frequencies (the difference between the
mark and space frequency) are used for FSK opera-
tion. This item allows you to select a shift frequency
for almost any FSK system.
