Understanding DSC Distress Calls
With your GPSMAP 3005C properly connected to a VHF radio with DSC output,
you can receive any DSC distress call within range. An alert message appears,
and an alarm sounds (if enabled) when a distress call is received. The alarm
sounds only for a distress call; position reports do not sound an alarm. Distress
calls are broadcasted to all DSC users in radio range and appear with a blue and
white checkered icon on the DSC tab’s Call List and Log sub tabs.
You can enter a caller’s name, if it is known. The caller’s name replaces the
MMSI number as a reference, when entered.
Understanding Position Reports
The position report operates similarly to the distress call. This type of contact is
like a phone call; no emergency alarms are set off, and the call is specific to the
receiver. Position reports are not broadcasted to all DSC users and appear with a
gold boat icon.
Call List Sub Tab
The Call List sub tab shows the 100 most recent calls, even if the unit is left
unattended. You can select any entry from the Call List to show an Entry Review.
Log Sub Tab
When DSC calls are received, they are automatically stored in the log, with
the latest call at the top. The unit can store up to 100 calls; after 100 calls are
received, the oldest is removed when a new call is received.
The Call List and Log sub tabs both show the call type, date/time, position, and
MMSI/Name. Pressing the Sort By (Call) Type, Sort By Time, Sort By Name,
Delete (only after highlighting a particular call), and Delete All soft keys allows
you to sort and delete calls.
To review a call or log entry:
1. From the
DSC
tab, highlight the
Call List
or
Log
sub tab.
2. Press up or down on the
ROCKER
to highlight the call you want to review.
3. Press
ENTER
.
Review DSC Waypoint
The Review DSC Waypoint Page operates similarly to the Distress Page and
Position Report Page. From this page you can also delete the displayed call. On
the DSC Review Waypoint Page, press the
Delete
soft key to delete the entry, or
press the
Create Wpt
soft key to create a waypoint.
