839WHEN RECEIVING A CALL78■ To receive a DSC callThe independent built-in DSC receiver circuit in the IC-M802 scans all distress/safety frequencies, therefore,the “distress,” “urgency” and “safety” calls on those fre-quencies can be decoded at all times.However, “routine,” “ships business,” “position request”and “group” calls on the other frequencies are receivedvia the transceiver’s receiver circuit. Therefore, thetransceiver must set to DSC watch mode to decodethese calls.• Monitoring the traffic frequencyMonitor the communication between the calling shipand a coast station, or the calling station transmissionvia voice on the traffic frequency.• Emergency alarm sounds until pushing [CANCEL/CALL], or short beeps sound, depending on thecalling format or category.* * * * * * * * * * * * * * * * * * * * * * * ** D i s t r e s s R L Y ** 1 2 3 4 5 6 7 8 9 ** * * * * * * * * * * * * * * * * * * * * * * *TrafficExit* * * * * * * * * * * * * * * * * * * * * * * ** D i s t r e s s ** 1 2 3 4 5 6 7 8 9 ** * * * * * * * * * * * * * * * * * * * * * * *TrafficExit TrafficExit************************* Geographic ** 123456789 *************************TrafficExit* * * * * * * * * * * * * * * * * * * * * * * ** G r o u p ** I C O M M 8 0 2 ** * * * * * * * * * * * * * * * * * * * * * * *TrafficExit************************* Geographic ** 123456789 *************************Exit* * * * * * * * * * * * * * * * * * * * * * * ** G e o g r a p h i c ** 1 2 3 4 5 6 7 8 9 ** * * * * * * * * * * * * * * * * * * * * * * *E x i t T r a f f i c• Transmit an acknowledgementWhen the following DSC is received, an acknowl-edgement must be sent back to the calling station.• Short beeps, or an emergency alarm sounds untilpushing [CANCEL/CALL], depending on the cat-egory.* * * * * * * * * * * * * * * * * * * * * * * ** I n d i v i d u a l ** I C O M M 8 0 2 ** * * * * * * * * * * * * * * * * * * * * * * *TrafficExit* * * * * * * * * * * * * * * * * * * * * * * ** P o s i t i o n R E Q ** I C O M M 8 0 2 ** * * * * * * * * * * * * * * * * * * * * * * ** * * * * * * * * * * * * * * * * * * * * * * ** T e s t ** A B C P o r t ** * * * * * * * * * * * * * * * * * * * * * * *A C KE x i tD When receiving a DSC callOne of the following actions should be performed whena DSC call is received depending on the received DSCformat (or category):• Wait for a voice transmission on the traffic frequency.• Transmit an acknowledgement with DSC or voice.D Display example and operation
