DSC Tab

The DSC tab (Marine Mode only) allows you to control and set up
the Digital Selective Calling (DSC) features on the GPSMAP 376C.
DSC uses marine VHF radio and GPS technologies to transmit and
receive location information. DSC is used by mariners for two major
operations: distress calls and position reporting.
For more information about DSC and Maritime Mobile Service
Identity (MMSI) numbers, see pages
DSC Page

127-128 in the "Appendix".

Understanding Distress Calls

With your GPSMAP 376C properly connected to a VHF radio with
DSC output, you can receive any DSC distress call within range.
An alert message appears and a tone sounds when a distress call is
received. The alarm only sounds on a distress call; position reports
do not sound the alarm. Distress calls are broadcast to all DSC users
in radio range and appear with a blue and white checkered icon on
the DSC Call List and Log tabs.
You can enter a caller's name, if it is known. The caller's name
replaces the MMSI number as a reference once 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.
Position reports are not broadcast to all DSC users and appear with a
gold boat icon.

Receiving DSC Calls

Each time you receive a distress call or position report, a review
page opens—either a DSC Position Report Page or a Distress Call
Page. Both pages contain identical fields to the DSC Entry Review
Page.
