18 DSC SETUP
18.1 INDIVIDUAL DIRECTORY
The GX2400 has a DSC directory that allows you to store a vessel or person’s
name, and the associated MMSI that you may wish to contact via individual
calls, position requests and position report transmissions.
To transmit an individual call, program this directory with the information of the
vessel you wish to contact, similar to a cellular phone's contact list.
Refer to section “ 11.4.1 Setting up the Individual / Position Call Directory ”
for details.
18.2 INDIVIDUAL REPLY
This menu item sets the radio to automatically (default setting) or manually
respond to a DSC Individual call requesting you to switch to a working channel
for voice communications. When “MANUAL” is selected, the MMSI of the call -
ing vessel is shown allowing you to see who is calling. This function is similar
to caller ID on a cellular phone.
Refer to section “ 11.4.2 Setting up the Individual Call Reply ” for details.
