3.5.18.2Individual Ship’s Call
An Individual Ship’s Call is a DSC call made to a specific ship identified by its MMSI number. There are three types: ROUTINE for normal calls, SAFETY for advisory alerts, and URGENCY for assistance when life is not in immediate danger.
The RAY215E can receive all three types of Individual calls but can only transmit ROUTINE Individual calls. As with any DSC operation, the call is made on channel 70.
Sending an Individual Ship’s Call
The RAY215E can only send a Routine Individual Call. The MMSI number of the ship to which the Individual Call is to be sent can be input manually or selected from a phonebook listing in memory. This section includes instructions for using both methods and for adding numbers to the phonebook.
Tip: You should first select the desired working channel before entering the DSC mode to send an Individual Ship’s Call. That way, that channel will already be displayed when the radio prompts for a working channel after the MMSI has been selected.
Note: Only simplex channels (those which are transmitted and received on the same frequencies) can be selected as the Individual Call working channel. See the frequency list in Section 6 to see which channels are simplex.
Using a manually input MMSI number
1.Press and release the DSC/PRI and D/L / I.C. keys simultaneously to place the unit in DSC mode. “70” appears in the large channel display, the DSC indicator illuminates, and “in” appears in the small channel display to designate individual call.
2.Press and release the DSC/PRI key. The DSC indicator appears, “0” is displayed in the large character display, and “1” is displayed in the small character display.
3.Rotate the Channel Select (CH) knob until the first digit of the other ship’s MMSI number appears in the large character display. (Channel UP/DOWN keys on the handset are disabled during this process).
4.Press the DSC/PRI key once to accept. The small character display now shows a “2”, designating the second digit in other ship’s MMSI number.
