12 DSC SETUP
12.1 INDIVIDUAL DIRECTORY
The GX1600 and GX1700 have a DSC directory that allows you to store a
vessel’s or person’s name and the MMSI number associated with vessels
you wish to transmit individual calls, position requests and position reports.
To transmit an individual call you must program this directory with information
of the persons you wish to call, similar to a cellular phones telephone direc-
tory.
Refer to section “9.5.1 Setting up the Individual / Position Call Directory”
for programming.
12.2 INDIVIDUAL REPLY
This menu item sets up the radio to automatically (default setting) or manu-
ally 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 calling vessel is shown allowing you to see who is calling. This function is
similar to caller ID on a cellular phone.
Refer to section “9.5.2 Setting up the Individual Call Reply” for setting.
