Understanding Position Reports
A Position Report is similar to a Distress Call except no alarm is
sounded. Position Reports are not broadcast to all DSC users and
are shown with a boat symbol.
Receiving DSC Calls
Each time you receive a Distress Call or Position Report, a
Notification Page is appears, and the call is placed in the DSC Call
List and Log. The Notification Page contains information about
the call including the type of call (distress or position report),
the MMSI number of the caller, a user definable name, the time
and date of the call, the Bearing and Distance from your current
position, and the coordinates of the caller. To see the caller’s
location on a map, select the Show Map button. To create a
waypoint at the caller’s location, select the Create Wpt button. To
close the Notification Page, press QUIT.
When a Distress Call or Position Report is placed in the Call List
and Log, the information on the Notification Page is retained.
To review a DSC call or log entry, highlight the entry, and press
ENTER. The DSC Entry Review window is identical to the
Notification window with one exception, the entry can be deleted.
