AIS TRANSPONDER
3
When the optional MA-500TR/MA-510TR
CLASS B AIS TRANSPON-
DER
is connected to your transceiver, an individual DSC call can
be transmitted to a selected AIS target, without needing to enter
the target’s MMSI code. In this case, the call type is automatically
set to Routine. See page 7 for connecting instructions.
To ensure correct operation of the DSC function, make
sure you correctly set the CH70 SQL LEVEL. See (
¤5
) of
the HM-195 instruction manual.
Step 1: Transponder’s operation
This instruction is for the MA-500TR. See the MA-510TR
Instruction manual for the MA-510TR’s step.
q
Select a desired AIS target on the plotter, target list or dan-
ger list display.
• You can also go to the next step whenever the detail screen of
the AIS target is displayed.
• Make sure the transceiver is in the normal operating mode. Other-
wise, you cannot make an individual DSC call using the transponder.
w
Push [DSC] to display the voice channel selection screen,
and then push [
Y
] or [
Z
] to select a desired voice channel*.
• Voice channels are already preset into the transponder in recom-
mended order.
* When a coast station is selected in step
q
, 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.
e
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 will dis-
play “DSC Transmission FAILED.”
