Sending Distress Calls
The ability to send and receive distress calls and their acknowledgements
on Channel 70 can literally be a lifesaver for you or another mariner.
NOTE
The DSC call will:
■
Sound the distress alarm at all receiving stations.
■
Inform receiving stations of your identity (MMSI).
■
Inform receiving stations of your position if you have a GPS
device connected or you have manually entered your position.
It will not provide the receiving stations with other distress information
such as the nature of your problem, number of persons aboard, injuries,
or the like. For that, you will have to communicate by voice on Channel 16
with the station that acknowledges your DSC distress call.
To Begin Sending A DSC Distress Call:
1. From Standby mode, lift the spring-loaded red door on
the transceiver and press the Distress button under it.
This will open the Distress menu with the arrow
pointing to SEND . You will have three (3) choices:
■
Send the distress call automatically with either
no position information if a GPS is not connected
or with the position provided by a connected GPS.
■
Manually enter your position, then send the
distress call.
■
Abort the distress call process and return to
Standby mode.
