DSC Call List
The DSC Call List displays the current calls received. The GPS can manage up to 50 calls. When
'calls' are received, they are updated constantly to give the most current information, even if the unit is
left unattended. Any entry from the Call List can be selected to show an Entry Review.
DSC Log
When DSC calls are received, they are automatically stored in the Log, with the latest call at the top.
The unit may store up to 100 logs. Once 100 logs are received, the oldest log file is removed when a
new call is received. The Log displays information of call Type, Date/Time, Position, and MMSI/Name.
Pressing MENU from this page allows you to 'Sort By Time', 'Sort By Name', 'Sort By (Call) Type', 'Delete'
(only after highlighting a particular call), and 'Delete All'.
To Review a Call:
1. From the DSC tab of the Main Menu and the Log or Call List tab highlighted, press DOWN Arrow
Keypad until the call you want to review is highlighted.
2. Press ENTER to select the call.
DSC Entry Review
The DSC Entry Review operates similarly to the Distress Page and Position Report Page. This page
has the additional option to 'Delete' the displayed call. From the DSC Entry Review, you can 'Delete' the
entry, 'Show on map', or 'Create Waypoint', and create a name for the entry.
DSC Directory
The DSC Directory acts much like a phone book. A user can save up to 50 contacts. The directory
lists by Name and MMSI number. Pressing MENU from this page allows you to create a 'New Item',
'Delete Item', or 'Delete All'.
