Digital Selective Calling (DSC)
The Ray54 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.When the DSC signal is received, the radio quickly switches over to
channel 70 and performs the corresponding operation.
Note: An MMSI number is required to operate the DSC equipment in this ra-
dio. You can obtain an MMSI from BoatUS (www.boatus.com). Once ob-
tained, you can program the MMSI number yourself one time only using the
menu operation described in My MMSI ID on page 72.
The Ray54 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 Save feature saves incoming DSC Calls and the caller’s associated
MMSI number directly into the phonebook
• Quick Call feature sends Individual Calls or Group Calls directly from
the phonebook, just like the redial function on a telephone
• Three (3) 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:
