Chapter 5: Digital Selective Calling (DSC) 37
Receiving Individual Calls
When an Individual Call is received, the radio sounds an alert tone and
displays the type of call, the name or MMSI number (if the callers MMSI
number has not been programmed into your Phonebook) of the caller and the
time the call was initiated. When an Individual Call from a station is received,
the radio may also ask you to send an acknowledge (ACK) back to the caller.
You are prompted to accept or decline the call.
To silence the alert tone:
Press any key. Automatic cancellation takes place after 2 minutes.
To cancel the mode without sending ACK:
Press the CLEAR/WX key. The alert tone is muted, the Individual Call is
interrupted and the normal screen appears on the display.
To accept the Individual Call:
Push the CH knob. The tone is muted (if you have not already pressed another
key) and an acknowledge (if requested) is sent to the originating station.
The LCD indicates a change of working channels has been made.
For Routine Calls, the channel changes to the one designated by the caller.
For Safety and Urgency Calls, the radio automatically switches to channel
16.
