OTHER FUNCTIONS
■ Individual DSC call
(Possible only when a transceiver is connected.)
When a transceiver is connected to the transponder, you can transmit an Individual
DSC call without entering the vessel’s MMSI code, by simply selecting its AIS target and
the voice channel on the transponder. The transceiver will use the transponder’s data
information and make the DSC call on channel 70, and then wait for the target vessel to
acknowledge it. After receiving the acknowledgment ‘Able to comply,’ use the transceiver
to communicate with the target vessel on the predetermined voice channel.
L The following transceivers can operate with this function. (As of November 2019)
IC-M605/IC-M605EURO/IC-M506/IC-M506GE/IC-M424G/IC-M400BB/
IC-M330/IC-M330GE/IC-M330G/IC-M220
L See page 42 for connecting to the transceiver.
NOTE: The data communication speed (baud rate) of NMEA1 must be set to 4800 bps
to send an Individual DSC call using the transponder.
1. Select an AIS target on the plotter display, Target,
Danger, or Friends list screen. (pp. 11, 16)
2. Push [ENT] to display the Menu window.
• The Menu window is displayed.
3. Select “Send DSC,” and then push [ENT].
• The “DSC TRANSMISSION” screen is displayed.
4. Push [▲] or [▼] to select a voice channel.
• Voice channels are already preset into the transponder
in the recommended order.
NOTE: When a base station is selected in step 1, a
voice channel will be specied by the base station.
Therefore you cannot change the channel. The
transponder will display “Voice Channel is specied
by the Base station,” in this case.
5. Push [ENT] to make the Individual DSC call.
• “Transmitting individual call” is displayed.
L If Channel 70 is busy, the transceiver stands by until
the channel becomes clear.
6. After making the Individual DSC call, “DSC
transmission completed.” is displayed.
• If the transceiver cannot make the call, “DSC
transmission failed.” is displayed.
7. Push [CLR] to return to the Main screen.
8. After receiving the acknowledgment from the AIS
target, use the transceiver to communicate. See the
transceiver’s manual for details.
