Steps between DSC frequencies
If the MMSI number is found in the station list, the frequencies are selected from the DSC
frequencies of the station if any; otherwise from the list of non distress DSC frequencies. If
DSC frequencies were selected from the Telephony display prior to the call these are default.
Distress frequencies cannot be selected in any way.
Transmission of a DSC call on MF/HF takes approx. 8 seconds. The Coast station if able to
comply will answer the call within 4½ minutes by sending a DSC Acknowledgement contain-
ing information on working frequencies for the subsequent traffic. When acknowledgement is
received lift the handset to set the radio to the working frequencies.
If no acknowledgement is received within 5 minutes, the equipment returns to the previous
telephony display and starts scanning if selected.
