8.3 Navigating the DSC menu
NEPTUNE offers many DSC functions. For this reason it was created a specific menu of settings
and activations accessible via the function keys as follows:
1. Access the “CALL”-Menu by pressing the related function key.
2. Press the function key corresponding to the word “Type” to select the type of desired call.
Once inside a sub-menu, you can return at any time to the main menu by pressing the C-button
and terminating the current operation.
8.4 Individual call (ROUTINE TO)
The user can carry out an individual call to a specific DSC station (a vessel or a costal station).
To carry out calls, you have to enter the MMSI code manually or recall it from the preprogramed
MMSI directory. For further details on programming the MMSI directory, see par. 10.5.
8.4.a Sending an individual call
You can carry out an individual call using the following procedure:
1. Press briefly the function key corresponding to CALL. On the display ap-
pears (J):
2. The outlined line below under “Routine to” appears if no owner name was
inserted in the column “Dir”, otherwise a similar situation may appear (K):
3. Press the function key “Ch 06” to access the sub-menu.
4. Press several times the function key “Chan” in order to select one of
the 23 available channels (simplex channels) and confirm by pressing
the E-button.
5. Like mentioned above, it is possible, to insert manually the address you
desire to call (using the alphanumerical keypad), or to select one of the
addresses previously stored (maximum 16) by pressing several times
the function key related to the word “DIR”.
6. Then, after you have selected the communication channel and the ad-
dress, the call can be carried out by pressing the function key corre-
sponding to “Send” and confirmed by pressing the E-button.
7. After the call execution the radio operates as follows:
- If you have carried out a call to a ship, after the call you will get an answer, the radio will move
to the channel previously selected under step 3-4.
8. At this point:
- If the call comes confirmed from the other part, the display shows
the message: (L). In this case the answer is reached from ship
100000000 and the possible communication channel will be CH06.
To confirm the reception of the received message, NEPTUNE will
emit an acoustic message that can be interrupted by pressing the
function key corresponding to ”OK” or “STOP”.
Pressing OK beyond interrupting the acoustic signalling, NEPTUNE
is syntonized on the communication channel (in our example 06).
If no function key comes pressed at that time (1 minute) the acoustic
message will extinguish automatically.
- If the call does not come comfirmed, the display will indicate (M), by
pressing the function key correponding to “Stop” the radio will return
to the normal radio mode.
Once inside a sub-menu, you can return at any time to the main individual
CALL-menu (Routine to) by pressing the C-button and terminating the
current operation.
