distress procedure:

reCeiVing a DsC Call
If your radio receives an individual DSC call from another station, it sounds an incoming call
tone and displays the name/MMSI number of the station calling you. To respond to the call,
select Send: Able-Comply; the radio sends an acknowledgement and automatically switches
to the designated response channel. To reject the call, select Send: Unable-Comply; the
radio advises the other station that you are unable to respond to the call.
If the DSC request contains a response channel that you are not allowed to use, the radio
displays Not Support CH; your only response option is Send: Unable-Comply.
If the radio receives a group or all ships call, it sounds an incoming call tone and
automatically switches to the designated response channel.
Receive log
Just like your telephone's caller ID list, your radio keeps track of the calls you receive. The
receive log is useful if you have been off your boat or away from your radio and want to see
who has tried to contact you. The radio displays the last 10 distress calls and the last 50
non-distress calls that it received. If you have unread incoming DSC calls, the radio displays
a Message icon. When you display all Distress and Other receiving logs, the message icon
disappears.
