Digital Selective Calling (DSC)

The Ray218 and Ray55 include 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 obtain an MMSI from BoatUS (www.boatus.com). Once obtained, you can program
the MMSI number yourself one time only using the menu operation described in "My
MMSI ID" on page 94.
The Ray218 and Ray55 include 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
• Five 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.
