57 Chapter 5: Digital Selective Calling (DSC) The Ray49 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. Note: An MMSI number is required to operate the DSC equipment in this radio. You can obtain an MMSI from BoatUS (www.boatus.com).
58 Ray49 Marine VHF Radio DSC Call Type Description GROUP Sends transmissions that are only received by radios sharing a common Group MMSI number. Up to 3 Group MMSI numbers can be stored and called. ALL SHIPS Sends out a message to all stations within range that you have important information but the situation is not serious enough for a Distress Call. All Ships calls should only be used if hailing for assistance on channel 16 fails.
Chapter 5: Digital Selective Calling (DSC) 59 5.2 Distress Calls For a Distress Call transmission, the Ray49 takes the position and time information (either from NMEA or manually input) along with your MMSI and converts it into a digital “packet”. When transmitted, this digital information lets other ships and shore stations equipped with appropriate DSC equipment know where you are and that you are in a Distress situation.
60 Ray49 Marine VHF Radio Designated Distress Call To send a distress call and specify its nature: 1. Press the red DISTRESS key. 2. Release the DISTRESS key. The Distress Call screen appears. 3.
Chapter 5: Digital Selective Calling (DSC) 61 Transmitting After the Distress transmission, the radio is automatically set to channel 16 at high power to listen for and respond to voice replies from Coast Guard or other vessels that may have received your Distress Call. To mute the alarm: Press CLR/WX. To manually cancel the automatic Distress resend: Press CLR/WX a second time. The Distress Call is resent randomly every 3.5 – 4.
2 Ray49 Marine VHF Radio Receiving a Distress Call The Ray49 receives distress messages sent by another vessel and/or acknowledgments (ACK) sent by a coast station to another vessel in distress. The radio also receives distress relays. Note: Class “D” DSC radios such as the Ray49 are forbidden by law from automatically acknowledging or relaying DSC distress calls. Upon receiving a distress call, you may hail the vessel in distress on channel 16 and standby to lend assistance if requested.

64 Ray49 Marine VHF Radio 5.3 DSC Phonebook The Phonebook stores up to 31 preprogrammed MMSI numbers that you can select for making an Individual Call. The numbers are stored by name and contain the station’s MMSI number. You can add, edit and delete entries from the Phonebook, much as you would on a cellular telephone. The NAME field can be up to 10 alpha-numeric characters (all capitals) in length. 13 symbols are also available.

Chapter 5: Digital Selective Calling (DSC) 67 The Ray49 automatically detects the correct procedures for you based on the type of MMSI number you enter manually or with or the phonebook. If “00” is detected as the first two characters of the MMSI, Coast Station procedures are implemented automatically. Note: When making a call to a coast station, you will not be asked to select a working channel because that will be provided by the coast station.
