1.3 DSC Operational Overview
Digital Selective Calling (DSC) is the global calling system adopted by the ITU-R
and IMO for selective calling of coast station and ship radio stations. The DSC
system is used for both safety and routine calling. The GMDSS requires the use
of DSC for distress alerting and safety calls.
1.3.1 LED warnings
The LED below the DISTRESS key lights continuously when the distress signal
is transmitted.
The ALARM LED blinks in red (and alarm sounds) when a distress or urgent
message is received. The LED can be extinguished and alarm silenced by
pressing the
CANCEL key.
The ALARM LED blinks in green (and alarm sounds) when a message other
than distress or urgent is received. Alarm is automatically silenced five seconds
