To receive a DSC call
The 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 received
via the transceiver’s receiver circuit. Therefore, the
transceiver must set to DSC watch mode to decode
these calls.
• Monitoring the traffic frequency
Monitor the communication between the calling ship
and a coast station, or the calling station transmission
via voice on the traffic frequency.
• Emergency alarm sounds until pushing [CANCEL/
CALL], or short beeps sound, depending on the
calling format or category.
