■
Making an Individual call using an AIS
transponder
When the optional MA-500TR
class
b
ais
transponder
is connected to your transceiver,
you can transmit an Individual DSC call to a selected AIS target, without entering the
target’s MMSI code. In this case, the call type is automatically set to “Routine.”
See page 45 for connecting instructions.
NOTE:
To ensure correct operation of the DSC function, make sure you correctly set
the CH70 SQL Level. (p.37)
1. Select an AIS target on the plotter, target list or danger list display.
L
You can also go to the next step whenever the detail screen of the AIS target is
displayed.
L
Confirm the transceiver is in the normal operating mode. Otherwise, you cannot make
an Individual DSC call using the transponder.
2.
Push [DSC] to display the Voice channel selection screen, and then push [▲] or [▼]
to select a Voice channel.
L
Voice channels are already preset into the transponder in the recommended order.
L
When a coast station is selected in step 1, a Voice channel will be specified by the
coast station, therefore you cannot change the channel. The transponder will display
“Voice Channel is specified by the Base station,” in this case.
3. Push [DSC] to transmit an Individual DSC call to the AIS target.
•If Channel 70 is busy, the transceiver stands by until the channel becomes clear.
•If the transceiver cannot make the call, the transponder displays “DSC Transmission
FAILED.”
