Digital Selective Calling (DSC)

The Ray49E includes equipment for Class "D" Digital Selective Calling (DSC). DSC
protocol is a globally applied system used to send and receive digital calls. DSC
uses a unique Maritime Mobile Service Identity (MMSI) number to direct DSC calls
directly to your radio, much like a telephone number. Most importantly, DSC
enables digital distress calls that automatically notify other ships and shore
stations where you are and that you are in a distress situation.
An MMSI ID number is required to operate the DSC equipment in this radio. You
Note:
can request an MMSI number from the same agency that issues radio or Ship Radio licenc-
es in your area. Once obtained, you can program the MMSI number yourself one time only
using the menu operation described in "My MMSI ID" on page 87.
The Ray49E includes the following DSC features:
• Separate receiver dedicated to handling DSC Calls on channel 70
• Position Request function sends GPS position data to or receives position data
from other stations
• Phonebook for automatically making DSC calls
• Quick Call feature sends Individual Calls or Group Calls directly from the
phonebook, just like the redial function on a telephone
• Three Group IDs for making DSC Calls only to stations in your group, such as a
flotilla or fishing fleet
DSC functions are fully described in Chapter 5.
