95.6 Stations receiving a DSC safety alert should not acknowledge receipt but simply tune their transceiver to the associated radiotelephony frequency/channel and await the radiotelephony announcement. 95.7 Should the initiating station wish that the safety alert is received only by a particular station, then the ‘single station’ call format should be selected. In this case the MMSI of the station must be known and programmed into the transceiver. Steps to transmit a DSC safety alert and subsequent safety call and message.
