BASIC OPERATION
■ Individual DSC call
When a transceiver* is connected to the transponder, you can
transmit an Individual DSC call without needing to enter the
vessel's MMSI code, by simply selecting it's AIS target and
the voice channel you wish to use on the transponder.
The transceiver will use the transponder's data information
and make the DSC call on channel 70, then wait for the target
vessel to acknowledge it. After receiving the acknowledge-
ment 'Able to comply,' use the transceiver to communicate
with the target vessel on the predetermined voice channel.
* See the leaflet that comes with the transponder for details of the
transceivers which can operate with this function.
See pages 41 and 42 for connecting instructions.

NMEA1 must be set to 4800 bps to send an Individual
DSC call using the transponder. (p. 11)
