When Receiving A Call; To Receive A Dsc Call - Icom IC-M802 Instruction Manual

■ 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.
D When receiving a DSC call
One of the following actions should be performed when
a DSC call is received depending on the received DSC
format (or category):
• Wait for a voice transmission on the traffic frequency.
• Transmit an acknowledgement with DSC or voice.
D Display example and operation
• 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.

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.
• Transmit an acknowledgement
When the following DSC is received, an acknowl-
edgement must be sent back to the calling station.
• Short beeps, or an emergency alarm sounds until
pushing [CANCEL/CALL], depending on the cat-
egory.
