Digital Select Calling (DSC) Operation
•
The Send menu displays when the Distress button is
pressed.
NOTE
This radio follows Class-D DSC protocol with a
dedicated Channel 70 receiver.
Sending Distress Calls
Sending and receiving distress calls and acknowledgements
on Channel 70 can be a lifesaver for mariners.
NOTE
The DSC call:
■ Sounds the distress alarm at all receiving stations.
■ Informs receiving stations of the sender’s identity
(MMSI).
■ Informs receiving stations of the nature of the
emergency.
■ Informs receiving stations of sending position
when a GPS device is connected or a position is
manually entered.
DSC operation does not provide receiving stations with
information like number of persons aboard or injuries. This
specific information must be communicated by voice on
Channel 16 to the station that acknowledges a DSC Distress
call.
To Send a DSC Distress Call:
1. From Standby mode, lift the spring-loaded red door on
the transceiver and press the Distress button. The
Distress menu displays with an arrow pointing to SEND.
