Garmin 278 Making a Distress Call, Setting Up DSC

New Directory Item Page

Enter the

MMSI number,

name, and a

comment (if

needed) in the

elds.

Highlight OK

and press

ENTER to save

the directory

entry.

After creating a New Directory Item, the name created is attached

to that particular MMSI number. If you return to the Log, the new

name appears under the corresponding MMSI number.

Another way to input a name is from the Entry Review Page or the

DSC Distress Call or DSC Position Report pages. The Name and

MMSI are sent to other Garmin GPS units: Only the MMSI numbers

are sent to other non-Garmin DSC users.

Making a Distress Call

To make a Distress Call, press the MayDay (or Distress Call) button

on your VHF radio. The call transmits on an emergency channel

with the MMSI number attached to the call, if you have DSC

support. Any DSC-equipped mariner (on sea or land) within range

can receive the call.

Setting Up DSC

Use the Setup sub tab to turn DSC on and off. If you have more

than one chartplotter and only want DSC to display on another

chartplotter, turn DSC off on this unit.

This Setup sub tab also allows you to simulate Distress Calls and

Position Reports while the unit is in Simulator Mode. Simulating

calls is helpful for practice before connecting to the real system. The

Distress Call simulator also helps to check if alarms are working

properly.
