15 DSC SETUP
15.1 INDIVIDUAL DIRECTORY
The HX870 has a DSC directory that allows you to store a vessel or person’s
name and the associated MMSI you wish to contact via individual calls, position
requests and position report transmissions.
To transmit an individual call you must program this directory with information of
the vessel you wish to contact, similar to a cellular phones telephone directory.
Refer to section “ 10.5.1 Setting up the Individual / Position Call Directory”
for details.
15.2 INDIVIDUAL REPLY
This menu item sets up 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 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 “ 10.5.2 Setting up the Individual Call Reply” for details.
15.3 INDIVIDUAL ACKNOWLEDGMENT
The radio can be setup to transmit a reply automatically (default) or set so the
radio will not reply to an individual call.
Refer to section “ 10.5.3 Enabling the Individual Call Acknowledgment” for
details.
15.4 INDIVIDUAL RINGER

a DSC individual call. The default setting is 2 minutes, however this can be
changed to 5, 10 or 15 seconds with the procedure below.
Refer to section “ 10.5.6 Setting up the Individual Call Ringer” for details.
