How to receive an All Ships call

1. When an All Ships call is received, an emergency alarm sounds. The display
shows the MMSI of the vessel transmitting the All Ships call and the radio changes
to the requested channel after 10 seconds.
2. Press any key to stop the alarm.
3. Monitor the requested channel until the all ships voice
communication is completed.
The display shows three soft keys:
[ACCEPT]: Accept the DSC All Ship call and to switch
to requested channel.
[PAUSE]: Temporarily disable automatic switching to
the requested channel. (In some cases automatically
switching to a requested channel might disrupt impor-
tant ongoing communications. This feature allows
commercial users to suspend channel switching and
stay on the working channel selected before the All Ships call was received.)
[QUIT]: Quit the automatic channel switching and revert to the last selected work-
ing channel.
Note: If no key is pressed within 10 seconds the radio automatically changes to
the requested channel.
4. Press the [QUIT] soft key to return to the channel display.

Individual Call

The Individual call contacts another vessel with a DSC VHF radio and automatically
switches the receiving radio to a desired communications channel. This feature is sim-
ilar to calling a vessel on CH16 and requesting to go to another channel. Up to 80 in-
dividual contacts can be programmed, in the Individual Directory.

How to register DSC stations to the Individual Directory

The Individual Directory allows you to save a vessel or person's name and the MMSI
number associated with vessels you wish to transmit Individual calls, auto polling, po-
sition request, and position report transmissions.
To transmit an Individual call you must program this directory with information of the
persons you wish to call, similar to how you program the telephone directory in a cel-
lular phone.
1. Press and hold down the CALL/MENU key until the
[Setup Menu] appears.
2. Rotate the CH knob to select the [DSC Setup] menu
then press the [SELECT] soft key.
3. Select [Individual Directory] with the CH knob then
press the [SELECT] soft key.
4. Select [ADD] with the CH knob then press the [SE-
LECT] soft key.
