Introduction
Digital Select Calling (DSC)
Operation
Sending a Geographical Call
This radio does not send Geographical calls. Only large
ships and shore stations with specially equipped radios send
Geographical calls.
Receiving a Geographical Call
Geographical calls are transmitted by specially equipped
radios to all stations in a particular area to alert only those
stations of the call and not stations in unaffected
geographical areas. When in an area to which a
Geographical call is made, the radio sounds the
geographical alarm and switches to the channel chosen by
the transmitting station.
When a Geographical Call Sounds:
1. Press any button to turn Off the alarm.
2. Read and write down the MMSI information of the vessel
sending the call as well as the date and time of the call.
3. Listen to the incoming voice message on the channel the
radio selects for the incoming Geographical call.
4. Place call information in Call Log.
5. Press one (1) of the following buttons to switch from the
Geographical call received to the Standby mode: Channel
16/9 button or ESC button.
