Using Digital Selective Calling (DSC) Features
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 or 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 but do not answer. 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 20 non-distress calls
that it received.
