on a Group MMSI must use the MID of the host country or
country of vessel registration (503 in Australia). The Group
ID should be based on a key vessel in the Group, and the
recommended system is to drop the last digit of the key
vessel’s MMSI and place a zero in front. e.g. a fleet of vessels
that has a lead vessel with a DSC self-ID of 503080110 could
use the Group MMSI of 050308011. This would then be
programmed into all fleet vessels as the special event
Group MMSI.
The ‘Test Call’ option can be used to make a test call to
your local Coast Station. The coast station should provide
an automated response to confirm that your radio’s DSC is
operating correctly.
The operations of the call options described above are
very similar.
1. Briefly press the key to enter the DSC menu.
2. Press the or keys to select ‘Individual Call’,
‘Position Request’, ‘Group Call’ or ‘Test Call’ and
press Enter.
3. You can choose to either manually enter the MMSI of the
other radio or recall it from your radio’s phone book.
